As a Type C drained protection system component, it does not rely on blocking water directly at the face of the structure. Instead, the 8mm stud profile creates a cavity between the membrane and the substrate, allowing moisture or water ingress to be managed behind the membrane and directed towards a suitable drainage channel, sump and pump arrangement where required. This makes Newton CDM 508 Mesh a dependable choice for basements, cellars, vaults, tunnels, retaining walls and vaulted soffits requiring controlled internal drainage.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eDirect Plaster And Render Finishes With A Built-In Mesh Key\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe key difference between Newton CDM 508 Mesh and a standard non-meshed cavity drain membrane is its thermally welded polyethylene mesh, which is fixed to the face of the membrane during manufacture. This meshed surface provides a mechanical key for plaster and render, allowing suitable internal finishes to be applied directly to the membrane in appropriate applications. This makes the product especially useful where the wall build-up needs to remain as slim as possible, or where a direct plastered or rendered finish is preferred over an independent dry-lining frame. The integrated mesh helps the finishing coat bond to the membrane face, while the studded rear profile continues to maintain the drainage cavity behind.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eDesigned For Earth-Retained Walls, Vaults And Tunnels\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eNewton CDM 508 Mesh is suitable for use on earth-retained walls and vaulted soffits, and may also be used in vaults and tunnels as part of a correctly designed Newton CDM waterproofing system. It is particularly suited to below-ground structures where the internal waterproofing system must manage moisture while also supporting a direct plaster or render finish. Unlike some direct-applied waterproofing systems, it does not usually require extensive and potentially damaging preparation to the wall surface, although the background must still be stable, suitably prepared, free from loose or organic material and capable of receiving secure fixings. Correct detailing remains essential to ensure the membrane forms part of a reliable, continuous waterproofing system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eComplete Type C Waterproofing System Compatibility\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eAs with any cavity drain membrane system, Newton CDM 508 Mesh must be used as part of a complete drained protection design that safely collects, controls and removes water. The membrane is mechanically fixed to the structure, with joints, corners, protrusions and terminations detailed using compatible Newton CDM tapes, ropes and ancillary products. The drainage provision is a critical part of the overall system, as the membrane is designed to manage water behind the finished surface rather than act as a standalone barrier. When correctly specified within the Newton CDM System, it provides a practical and professional solution for basement conversions, structural waterproofing upgrades and below-ground refurbishment projects where long-term moisture control is required.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eDurable, Inert And Suitable For Grade 3 Environments\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eNewton CDM 508 Mesh is manufactured from inert material that is non-polluting to drinking water and resistant to a wide range of substances commonly found in below-ground structures.

The studded profile creates a cavity behind the membrane so water ingress can be managed and directed towards the drainage system, while the mesh surface provides a key for plaster or render. This dual function is particularly beneficial in habitable below-ground areas where both waterproofing performance and a direct internal finish are required.\u003c\/p\u003e\n\u003cp\u003eThe membrane’s resistance profile is important for long-term below-ground use. It is highly resistant to water, alkalis, saline solutions and organic acids, and is not affected by minerals or hydrocarbons. These properties are useful because basement and retaining wall environments can contain moisture, salts and contaminants that may affect less durable materials. Its rot-proof construction and resistance to bacteria, fungi and small organisms further support long-term performance in damp, concealed spaces.\u003c\/p\u003e\n\u003cp\u003eThe thermally welded mesh face improves finishing practicality. A standard smooth cavity drain membrane normally requires an independent lining system or battens to receive plasterboard, whereas Newton CDM 508 Mesh provides a surface key for suitable plaster or render systems. This can simplify the wall build-up in appropriate applications and reduce overall lining depth, which is often important in basement conversions and refurbishment works where internal space is limited.\u003c\/p\u003e\n\u003cp\u003eThe product is also beneficial because it avoids reliance on aggressive substrate preparation. The membrane is mechanically fixed and forms part of a drained system, so the existing wall does not usually need the same level of preparation required for direct-applied tanking coatings.

It forms part of the Newton CDM System, which relies on correct design, drainage, fixing, sealing, finishing and maintenance rather than the membrane acting as a standalone water barrier. The product information states that Newton CDM 508 Mesh should be installed by those with structural waterproofing experience, with trained specialist contractors recommended for correct system design and installation.\u003c\/p\u003e\n\u003cp\u003eBefore installation begins, the working area should be assessed for safety, access, lighting, ventilation and the condition of the existing structure. Suitable PPE should be worn, including gloves and safety glasses, particularly when drilling through the membrane, cutting the sheets, using fixing plugs, applying tapes or using a heat gun. Where the membrane is being installed to high walls, vaulted soffits or overhead details, safe access equipment such as staging or scaffold should be used. A 110V SDS hammer drill, sharp cutting tools and hot air gun should be handled carefully, with all drilling and fixing carried out in a controlled manner to avoid damaging the membrane, substrate or hidden services.\u003c\/p\u003e\n\u003cp\u003eThe product should only be used for the intended applications and within the correct Newton CDM waterproofing system build-up. Newton CDM 508 Mesh is designed for walls, vaults and tunnels, and for suitable vaulted or sloping soffit applications where the membrane can drain correctly. It should not be used as an isolated waterproof sheet, and it should not be installed where the waterproofing design does not include adequate collection and removal of water from behind the membrane system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSystem Design Principles\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eNewton CDM 508 Mesh is used as part of a Type C cavity drain waterproofing system. The system does not work by resisting hydrostatic pressure at the face of the structure. Instead, the studded membrane creates a depressurisation space behind the internal finish, allowing water ingress to be controlled, managed and directed towards drainage channels, sump chambers or safe natural drainage. For this reason, drainage is not an optional extra. It is central to the performance of the system.\u003c\/p\u003e\n\u003cp\u003eThe waterproofing design should take account of BS 8102:2022, the structure type, the intended internal environment, the expected water pressure, the condition of the wall or soffit, and the proposed finish. The external structure should be capable of controlling the rate of water ingress so that it does not exceed the ability of the cavity drain system to collect and remove water. Where water is entering heavily through construction joints, movement joints, cracks or wall\/floor junctions, the flow should be reduced or controlled before the cavity drain membrane system is installed.\u003c\/p\u003e\n\u003cp\u003eFor existing structures, the designer should consider that the original construction may not have been designed to resist modern expectations of water pressure. Older brick structures often leak most freely at the wall\/floor junction, while more modern concrete structures may leak through kicker joints, movement joints, construction joints or cracking. For new-build structures, the concrete structure, construction joints and crack control measures should be designed properly so that the cavity drain system is dealing with controlled leakage rather than unmanaged water ingress.\u003c\/p\u003e\n\u003cp\u003eNewton CDM 508 Mesh is not suitable for gas protection systems. Where radon, methane or hydrocarbon gas protection is required, an appropriate gas-rated system should be specified instead. The meshed membrane is intended for waterproofing and damp management applications where the wall or vaulted soffit will receive plaster, render, hydraulic lime or plasterboard bonded by dabs directly to the meshed face.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSuitable Substrates And Areas Of Use\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eNewton CDM 508 Mesh is suitable for walls formed from concrete, brick and concrete block.

The membrane must be able to drain without sagging or creating pockets where water can pond behind the system.

CDM Joint Tape is used to seal flanged joints and suitable stud-into-stud laps. CDM Rope is used where a flange joint is not possible, where a stud-over-stud joint is required, and where fixing plugs need to be sealed on vaulted or overhead applications. CDM OverTape is used for repairs, reveal details and certain abutting or perimeter details.

Water should be directed to a drainage channel, sump chamber or safe natural drainage route. Standing water behind the system should be avoided because it can lead to silt or lime scale build-up and can compromise the ability of water to flow to the drainage point.\u003c\/p\u003e\n\u003cp\u003eCDM BaseDrain is normally positioned at the wall\/floor junction to collect water from behind the wall membrane and receive water at the vulnerable junction between wall and floor. It can connect to sump chambers, gullies, waste pipes or other designed drainage points, and inspection ports can be incorporated to allow future maintenance. Where deeper floor finishes are used, CDM Condensation Strip may be required to maintain a condensation gap so any condensation forming on the membrane face can be collected by the drainage channel rather than pooling at the floor edge.\u003c\/p\u003e\n\u003cp\u003eWhere a pumped system is required, the sump and pump arrangement must be sized to suit the expected water ingress, pumping head, discharge distance and drainage layout. A common design guide is one sump for every 50m of CDM BaseDrain, although this depends on the water-tightness of the structure, soil conditions, slab levels and the likelihood of greater than normal water ingress. Battery back-up, alarms, monitoring and dedicated discharge arrangements should be considered where the space relies on pumping to remain dry.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWall Installation\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eNewton CDM 508 Mesh is generally fixed vertically because the rolls are heavier and supplied in 2.0m wide rolls rather than 2.4m high rolls.

A hole is drilled through the centre of a stud near the top edge of the membrane using the correct drill bit for the selected fixing plug. The hole should be drilled to a depth greater than the fixing. The plug is then hammered into the pre-drilled hole until it sits flush within the stud and seals the fixing point. The membrane should then be levelled using a long spirit level or laser level, and a second fixing installed approximately 2m along the top of the sheet so the membrane hangs level.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/newton-cdm-508-mesh-membrane-8mm-studded-waterproof-meshed-w-2-0m-x-l-20m-40m-basement-membranes-959_1024x1024.webp?v=1782905731\" alt=\"Newton CDM 508 MESH Membrane - 8mm Studded Waterproof MESHED Membrane - (W) 2.0M x (L) 20M (40M²) - Basement Waterproof\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003eEach following sheet should be positioned to overlap the previous sheet by at least the width of the flange.

Fixings should be installed in a square pattern at 350mm centres, with an additional fixing placed in the centre of each group of four fixings so the pattern resembles the number 5 on a dice. This results in all fixings being at a maximum of 250mm centres. On very flat walls, the horizontal and vertical centres may be increased to 400mm, provided the centre fixing is still installed so the final centres are not more than 300mm.\u003c\/p\u003e\n\u003cp\u003eFixings should be kept neat and aligned wherever possible. This is important for both the visual quality of the membrane installation and the performance of the subsequent finish. Poor fixing alignment, insufficient fixing density or fixings placed into weak substrate can allow the membrane to move, which may affect plaster, render or board adhesion.

The sealing material must be pressed firmly against the membrane to ensure proper adhesion. For 8mm membranes such as Newton CDM 508 Mesh, the preferred joint is normally the flanged joint where the flat flange is available. The flange should cover a minimum of two rows of studs, with CDM Joint Tape positioned beneath the flange on the flat section between the last two rows of studs. The backing paper should remain in place until the upper membrane is correctly positioned, then be removed while the two membrane layers are pressed firmly together.\u003c\/p\u003e\n\u003cp\u003eA locked flanged joint may be used where the first row of studs on the next sheet interlocks with the last row of studs on the previous sheet. This helps ensure the next sheet is installed square and is useful on large areas or where alignment is particularly important. Where a flange is not available but the studs line up correctly, a stud-into-stud joint may be formed with a minimum three-stud overlap using CDM Joint Tape. Where neither a flanged joint nor a stud-into-stud joint is possible because the studs do not interlock, a stud-over-stud joint should be made with a minimum three-row overlap and CDM Rope positioned between the last two rows of studs on the reverse side of the upper membrane.\u003c\/p\u003e\n\u003cp\u003eWhere joints in Newton CDM 508 Mesh have been sealed with CDM Joint Tape, CDM Rope or CDM OverTape, Newton Mesh Tape should be applied over the sealed joint wherever plaster or render will be applied directly.

Its purpose is to stiffen the membrane and provide a rough, absorbent backing for subsequent coats. The scratch coat and float coat should each be allowed to dry for not less than 7 days, preferably 10 days or longer where possible. Shorter curing periods increase the risk of cracking. The render must be dampened as required during curing, and in warm weather it should be protected from excessive drying by covering with damp hessian sheets and plastic sheeting. Before applying the second coat, a small section should be carefully drilled or scratched out behind the mesh within the membrane stud to confirm that the scratch coat is fully cured, as the surface may appear cured before the deeper material behind the mesh has properly hardened.\u003c\/p\u003e\n\u003cp\u003eA smooth render finish is not recommended.

The membrane should not be left exposed where the fire strategy requires it to be covered. Fire-resistant membrane options tested and classified to B-s2,d0 are available from Newton for projects where the specification requires a higher fire performance.\u003c\/p\u003e\n\u003cp\u003eThe fire protection requirement should be considered before internal finishes are selected. Plaster, render, plasterboard or other approved finishes should be installed in a way that protects the membrane while maintaining the waterproofing design.

Basements and earth-retained rooms are often more difficult to ventilate naturally, particularly where most of the external walls are below ground. Mechanical ventilation is commonly required to control humidity, reduce condensation risk and support the internal environment. BS 8102:2022 recognises that ventilation, dehumidification or air conditioning may be necessary for Grade 3 spaces, depending on the intended use.\u003c\/p\u003e\n\u003cp\u003eCondensation risk increases where insulation prevents heat from reaching the waterproofing membrane face, causing surfaces to become cooler and more likely to reach dew point. Relative humidity should therefore be controlled through suitable ventilation. Where CDM BaseDrain is used, spacers to the reverse side of the upstand can collect condensation from the face of the wall membrane and allow it to enter the drainage channel. Where floor finishes are deeper, CDM Condensation Strip may be required to maintain a condensation gap.\u003c\/p\u003e\n\u003cp\u003eIf the condensation gap is sealed for a specific reason, such as a gas barrier design in another compatible system, the ventilation system must work as designed.

A small patch of CDM OverTape should then be applied over the repair. The same method can be used where a fixing has failed because the substrate is unsound or the fixing plug expansion pin has not achieved a secure hold. The failed position should be repaired, and a new stud should be selected and drilled for the replacement fixing.\u003c\/p\u003e\n\u003cp\u003eIf the membrane is accidentally cut or pierced on a vertical wall, the surface should be cleaned and the damage sealed with CDM OverTape. The tape should run along the full length of the cut, bridge both edges and extend at least 25mm beyond the furthest points of the damage. Ragged rips and tears should be treated in the same way. If a hole is created, CDM OverTape may be used where the hole can be bridged in one piece with at least a 25mm margin around the damaged area. Larger holes may require a membrane patch large enough to cover the damage with a margin beyond the hole. If the patch sits neatly into the studs, the edges can be sealed with CDM Joint Tape around the perimeter. If the studs do not interlock and a ridge is formed, CDM OverTape should be used to bridge around the patch perimeter onto the main membrane.\u003c\/p\u003e\n\u003cp\u003eWhere damage occurs to a vaulted ceiling, the same repair principles apply, but CDM OverTape should always be used to bridge or seal the damage.

It is designed for earth-retained walls, vaulted soffits, vaults and tunnels where water ingress needs to be managed internally. The rear studded profile creates a cavity behind the membrane, allowing water to move towards a suitable drainage channel, sump or pump system. The face of the membrane has a polyethylene mesh thermally welded to it during manufacture, providing a key for suitable plaster or render finishes. This makes it useful where waterproofing and direct internal finishing are both required.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How does Newton CDM 508 Mesh Membrane work?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh Membrane works by creating a drained cavity behind the internal finish. The 8mm stud profile holds the membrane away from the wall or vaulted surface, allowing water or moisture to move behind it instead of becoming trapped against the finished room surface. That water is then directed towards suitable drainage, such as Newton CDM BaseDrain, outlets, sump chambers or pump systems. The meshed face performs a separate finishing role by providing a mechanical key for plaster, render, hydraulic lime or suitable bonded board systems. This means the membrane manages water behind the system while supporting a direct finish on the room side.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What is Newton CDM 508 Mesh used for?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is used for waterproofing below-ground walls, vaulted soffits, vaults and tunnels where a Type C drained protection system is required. It is particularly useful in basements, cellars and habitable below-ground rooms where damp or water-bearing structures need to be isolated from internal finishes. The membrane creates a drainage cavity behind the finish while its meshed surface allows suitable plaster or render to bond directly to the membrane face. This makes it a practical option where a slimmer wall build-up is desired, or where an independent dry-lining frame would take up too much space. It must still be used with suitable drainage and sealing accessories.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Is Newton CDM 508 Mesh suitable for basement waterproofing?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh is suitable for basement waterproofing when used as part of a correctly designed Newton CDM System. It is intended for earth-retained walls and similar below-ground structures where water ingress needs to be controlled and safely drained away. In basement conversions, the membrane helps separate internal finishes from damp, salt-contaminated or water-bearing walls while allowing moisture to move behind the membrane towards the drainage system. Its meshed face is useful where a direct plaster or render finish is required. When correctly specified, installed and ventilated, it can contribute to internal environments up to Grade 3 under BS 8102:2022.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What is the difference between Newton CDM 508 Mesh and standard Newton CDM 508?\u003c\/h3\u003e\n\u003cp\u003eA) The main difference is the integrated meshed face. Standard Newton CDM 508 is a non-meshed 8mm cavity drain membrane that normally requires dry-lining, battens, frames or other suitable finishes in front of it. Newton CDM 508 Mesh has a polyethylene mesh thermally welded to the face, giving plaster, render, hydraulic lime or compatible bonded board systems a surface to grip. Both products manage water using an 8mm drainage cavity, but Newton CDM 508 Mesh is designed for applications where the finish is applied directly to the membrane. This can reduce build-up depth and make it useful in tighter basement or refurbishment spaces.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM 508 Mesh be plastered directly?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh can receive a direct plaster finish because its thermally welded mesh face provides a mechanical key. The recommended plaster is Tarmac Whitewall One Coat, but it should not be applied as one single coat. It should be applied in two coats, with a 6mm scratch coat followed by a 6mm second or float coat. If a finishing coat is required, this should be around 3mm. A minimum drying period of 24hours should be allowed between coats. Decoration should not begin until the plaster is thoroughly dry, as trapped moisture or premature decoration can affect the final finish quality.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM 508 Mesh be rendered directly?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh can receive an internal render finish when the correct method is followed. A sand, cement and lime render should be applied in two coats to a total thickness of 14mm, with a 3mm skim coat added after full curing if required. The scratch coat should be 7mm thick and worked firmly into the mesh to stiffen the membrane and form a sound backing. The second coat should also be 7mm thick. Each coat should be allowed to dry for at least 7 days, preferably 10 days or longer. Rushing the cure can increase the risk of cracking or weakness.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can hydraulic lime be used on Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh can receive a hydraulic lime finish where this is specified. NHL 3.5 should be used to a combined depth of 20mm, formed from a 10mm scratch coat and a 10mm second or float coat. The mix ratio is 2.5 parts sand to 1 part NHL 3.5, prepared in line with the manufacturer’s instructions. The scratch coat must be pushed firmly into the mesh and checked the next day so any cracks can be rubbed out. It should then be left for at least 7 days before the second coat is applied. The finish must be protected from draughts and temperature extremes.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can plasterboard be fixed to Newton CDM 508 Mesh with adhesive dabs?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, plasterboard can be fixed to Newton CDM 508 Mesh using the dot and dab method, creating a dry surface ready for decoration. The dabs should be applied to the heads of the fixing plugs, along board edges and to the membrane surface, covering around 50% of the CDM 508 Mesh face. Care is needed with laminated or insulated plasterboard because building regulations may require mechanical fixings, and those fixings can breach the waterproofing membrane. Where insulation is required, it may be better to use a non-meshed membrane with an independent dry-lining frame rather than fixing insulated boards through the meshed membrane.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Where should Newton CDM 508 Mesh Membrane be used?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh Membrane should be used on walls, vaults, tunnels and suitable vaulted or sloping soffits where a drained cavity membrane and a direct finish are required. It is useful in basement waterproofing, cellar conversions, internal refurbishment of damp structures, earth-retained walls and habitable below-ground spaces. It is especially beneficial where internal space is limited and the project needs a plaster, render, hydraulic lime or bonded plasterboard finish without a full independent frame. The membrane should be selected only where drainage can be designed correctly and where the substrate can receive secure mechanical fixings. It is not a standalone waterproofing sheet.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM 508 Mesh be used on floors?\u003c\/h3\u003e\n\u003cp\u003eA) No, Newton CDM 508 Mesh should not be used as a floor membrane. It is designed for walls, vaults, tunnels and suitable vaulted or sloping soffit applications where the meshed face can receive plaster, render, hydraulic lime or bonded plasterboard. Floor waterproofing requires a suitable Newton floor membrane selected for the expected loading, screed, insulation or flooring build-up. Using Newton CDM 508 Mesh on a floor would be outside its intended use and could compromise the system design. If a project includes both walls and floors, Newton CDM 508 Mesh may be used on walls while a separate compatible Newton floor membrane is specified for the floor area.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM 508 Mesh be used on flat soffits?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is not suitable for flat soffits. Soffit waterproofing should be limited to appropriate vaulted, arched or sloping applications where water can drain and ponding can be avoided. Flat soffits are difficult because water may sit behind the membrane if there is not enough fall, and sagging can create pockets where water collects. In a Type C system, water must always be able to move towards the designed drainage route. If a flat soffit requires waterproofing, a different design or specialist technical advice should be considered. Newton CDM 508 Mesh should not be treated as a routine membrane for flat overhead surfaces.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What substrates can Newton CDM 508 Mesh be fixed to?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh can be fixed to walls formed from concrete, brick and concrete block. It may also be fixed to ICF construction where special longer fixing plugs are used. The substrate must be capable of accepting a secure mechanical fixing, because the membrane and finish depend on the fixings holding properly. Weak, friable, loose or heavily deteriorated backgrounds should be repaired or made good before installation. Vaulted or arched soffits must also be stable and suitable for fixing. The wall does not need to be prepared like a direct-applied coating system, but it must still be sound enough for safe, secure and consistent membrane installation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What preparation is needed before installing Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Before installing Newton CDM 508 Mesh, the area should be assessed and cleared of materials that could decay or support mould growth behind the system. Timber, skirting boards, timber plates, old wallpaper and other organic materials should be removed. If rot is present, it should be treated by a specialist, and any mould should be cleaned and sterilised with a suitable fungicidal wash. Loose material, sharp projections, unstable areas and large depressions should be addressed so the membrane can be fixed neatly and securely. The surface does not need to be decorative-smooth, but it must be clean, stable and capable of receiving the correct fixings.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Why is drainage important with Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Drainage is essential because Newton CDM 508 Mesh does not stop hydrostatic pressure as a standalone barrier. It is part of a Type C cavity drain system, which controls water by allowing it to enter the cavity and then directing it away safely. Water should be collected by channels such as Newton CDM BaseDrain and discharged to a sump chamber, pump or safe natural drainage route. If drainage is missing, blocked or undersized, water can build up behind the system and compromise performance. The design must consider likely water ingress, groundwater conditions, discharge routes, pump capacity and maintenance access. The membrane only works properly as part of a complete drainage system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How is Newton CDM 508 Mesh fixed to walls?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is generally fixed vertically, with the mesh face towards the room and the studded side against the substrate. A hole is drilled through the centre of a stud near the top edge using the correct drill bit for the chosen fixing plug. The plug is then driven into place until it sits flush within the stud and seals the fixing point. The membrane should be levelled using a spirit level or laser level before further fixings are installed. Following sheets should overlap correctly and be sealed with Newton CDM Joint Tape. Good alignment is important because poor positioning can cause kinks, weak joints or finishing difficulties.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What fixing centres are required for Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh needs closer fixing centres than non-meshed membranes because it carries a direct plaster, render or bonded board finish. Fixings should be installed in a square pattern at 350mm centres, with an additional fixing in the centre of each group of four fixings, similar to the number 5 on a dice. This means all fixings are at a maximum of 250mm centres. On very flat walls, horizontal and vertical centres may be increased to 400mm, provided the centre fixing is still included so final centres are not more than 300mm. Secure, well-aligned fixings help reduce movement and improve finish performance.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How are joints in Newton CDM 508 Mesh sealed?\u003c\/h3\u003e\n\u003cp\u003eA) Joints in Newton CDM 508 Mesh should be sealed using compatible Newton CDM accessories, selected according to the joint type. The preferred joint is usually a flanged joint, with Newton CDM Joint Tape placed beneath the flange between the membrane surfaces. Where a flange is not available but the studs interlock correctly, a stud-into-stud joint may be formed with a minimum three-stud overlap and CDM Joint Tape. Where the studs do not interlock, a stud-over-stud joint should be made with a minimum three-row overlap and CDM Rope. All sealing surfaces must be clean, dry and dust free, and the joint should be pressed firmly to ensure adhesion.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) When should Newton Mesh Tape be used with Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Newton Mesh Tape should be used wherever a sealed joint, repair or detail on Newton CDM 508 Mesh needs the plaster or render key reinstated. Products such as Newton CDM Joint Tape, CDM Rope and CDM OverTape can create the waterproof seal, but they do not provide the same meshed surface required for direct finishing. Applying Newton Mesh Tape over the sealed area restores a suitable fleece key, allowing plaster or render to bond across the joint rather than sitting on a plain tape or rope detail. This is especially important over laps, repairs, protrusions, door reveals and other areas where the meshed surface has been interrupted.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM 508 Mesh be used on vaulted soffits?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh can be used on vaulted soffits and arched structures where the membrane can be fixed and detailed so water drains correctly. The membrane must be held tight to the soffit without sagging, and laps must not create pockets where water can pond. On vaulted ceilings, the standard rubber sealing washer supplied with some Newton CDM plugs should not be used. Instead, a ring of Newton CDM Rope should seal the plug fixing. Fixings are installed through the centre of the membrane studs and should be kept aligned. Vaulted installations require careful planning, safe access, accurate cutting and reliable drainage detailing.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How are pipes and services sealed through Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Pipes, cables, conduits and other services should be avoided through Newton CDM 508 Mesh where possible because they interrupt the waterproofing layer. Where a penetration is unavoidable, the membrane should be cut neatly around the service and sealed with suitable Newton accessories such as CDM Rope, CDM OverTape, pipe collars or pipe sleeves. Where adhesion to the protrusion needs improvement, priming may be required depending on the detail. Once the waterproof seal is formed, Newton Mesh Tape should be used over non-meshed sealing products where plaster or render will continue across the area. Services in vaulted areas should ideally be moved to vertical surfaces wherever practical.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Does Newton CDM 508 Mesh need protecting after installation?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh should be protected by suitable finishes after installation. It is designed to receive plaster, render, hydraulic lime, bonded plasterboard or other specified internal finishes, but it should not be left exposed to long-term UV light, impact, abrasion or general wear. Its service life depends on correct specification, installation and protection. Follow-on trades should avoid cutting, drilling, over-fixing or damaging the membrane before it is covered. Any damage must be repaired before finishes are applied. The membrane also needs protection from fire by the selected surface finish. Leaving it exposed or vulnerable to site damage can compromise the waterproofing system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What fire rating does Newton CDM 508 Mesh have?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh has a fire rating of Euroclass F under BS EN 13501-1. It should therefore be treated like a plastic-based construction product that must be protected from fire by suitable surface finishes. The membrane should not be left exposed where the fire strategy requires a protected build-up. Plaster, render, plasterboard or other approved finishes should be installed in a way that covers and protects the membrane while maintaining the waterproofing design. Where a project requires higher fire performance, Newton has fire-resistant membrane options tested and classified to B-s2,d0, but those would need to be specified separately according to the project requirements.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Is Newton CDM 508 Mesh suitable for gas protection?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is not suitable for gas protection systems. It should not be relied upon for radon, methane or hydrocarbon gas resistance. If a project requires gas protection as well as waterproofing, an appropriate gas-rated Newton system should be specified instead. This is important because below-ground projects can face both water ingress and ground gas risks, but the products used to manage each risk must be suitable for that purpose. Newton CDM 508 Mesh is designed for waterproofing and damp management where a meshed surface is needed for plaster, render, hydraulic lime or bonded plasterboard. Gas protection requires a separate specification.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What ventilation is needed with Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Ventilation is important in rooms waterproofed with Newton CDM 508 Mesh, especially where the space will be habitable. Basements and earth-retained rooms are often difficult to ventilate naturally because many walls are below ground. Mechanical ventilation, dehumidification or air conditioning may be needed to control relative humidity and reduce condensation risk. BS 8102:2022 recognises that environmental control is important for Grade 3 spaces. Condensation can occur when warm, moist air meets cooler surfaces, particularly where insulation reduces heat reaching the membrane face. The wider Newton CDM System can include condensation collection details, but room ventilation should still be properly designed for the intended use.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What technical data applies to Newton CDM 508 Mesh?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is manufactured from HDPE and is supplied in 2.0m x 20m rolls, covering 40m². It has a density of 505g\/m², a membrane thickness of 0.6mm, a stud height of 7.0mm and a packaged weight of 20.2kg. Its working temperature range is -50°C to +80°C, and the softening temperature is 126°C. The membrane passes water tightness testing at 60kPa for 24hours to EN 1928. Tensile strength is listed as 416N in the machine direction and 488N in the cross direction, with compressive strength stated as 180kN. Fire resistance is listed as Euroclass F.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Is Newton CDM 508 Mesh BBA Certified?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh is supported by BBA Agrément Certificate 22\/6357, giving independent assessment for defined waterproofing applications when used in accordance with the relevant system guidance. It is also intended for use within designs that consider BS 8102:2022, particularly where Grade 3 internal environments are required. The product is guaranteed against deterioration for 30 years and has a stated life expectancy of at least 100 years, or equal to the design life of the building when correctly installed and protected. The membrane is inert, rot-proof, non-polluting to drinking water and resistant to a wide range of below-ground contaminants.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How long does Newton CDM 508 Mesh last?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is intended as a long-term waterproofing component when correctly specified, installed and protected. The supplied information states that it is guaranteed against deterioration for 30 years and has a life expectancy equal to the design life of the building, with a stated life expectancy of at least 100 years. This durability depends on the membrane being protected from UV light, physical damage, abrasion, fire exposure and unnecessary puncturing. It must also be used as part of a maintained cavity drain system, because the long-term performance of the waterproofing relies on drainage, pumps, inspection access and discharge routes continuing to work properly.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Does Newton CDM 508 Mesh require maintenance?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh itself requires very little maintenance once it is installed and protected behind the final finish. However, the wider Newton CDM System does require maintenance because drainage channels, sump chambers, pumps, alarms and discharge routes must remain operational. A competent person should inspect and service the system at least once per year, with additional pump manufacturer requirements followed where applicable. Maintenance may include flushing drainage channels, removing debris from sumps, checking pumps, testing alarms, inspecting discharge pipes and confirming electrical connections. If the waterproofed space depends on pumping, a suitable battery back-up system should be considered to protect the area during a power failure.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM 508 Mesh be repaired if damaged?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM 508 Mesh can be repaired if it is damaged, but repairs should be completed before finishes are applied. If the wrong stud is drilled, the stud should be cleaned, plugged with Newton CDM Rope and covered with a small patch of CDM OverTape. Cuts, rips or punctures should be cleaned and bridged with CDM OverTape, extending at least 25mm beyond the damaged area. Larger holes may require a membrane patch sealed around the perimeter. Where the repair area will receive plaster or render, Newton Mesh Tape should be applied over the sealed repair to reinstate the surface key. All repair surfaces must be clean and dry.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the main limitations of Newton CDM 508 Mesh Membrane?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM 508 Mesh is not a standalone waterproofing product and has no ability to withstand water pressure by itself. It must be used as part of a properly designed Type C cavity drain system with suitable drainage, discharge, inspection access and maintenance. It is not suitable for flat soffits, floor applications or gas protection systems. It also relies on correct fixing density, sound substrates, clean and sealed joints, suitable ventilation and appropriate finishing methods. Plaster and render must be applied correctly and allowed to cure fully before decoration. The membrane should not be punctured by future fixings, and any later alterations should be checked with a specialist first.\u003cbr\u003e\u003c\/p\u003e\n\u003ch5\u003eData Sheets\u003c\/h5\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_TECH.pdf?v=1782477109\" target=\"_blank\"\u003e\u003cstrong\u003eTechnical Data Sheet\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_TECH.pdf?v=1782477109\" target=\"_blank\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_TECH_160x160.jpg?v=1782476926\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_CDM_MANUAL_4436e4d8-2bd0-4917-9d4c-2fef110d4b56.pdf?v=1782477479\" target=\"_blank\"\u003e\u003cstrong\u003eNewton CDM Installation Manual\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_CDM_MANUAL_4436e4d8-2bd0-4917-9d4c-2fef110d4b56.pdf?v=1782477479\" target=\"_blank\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_CDM_MANUAL_160x160.jpg?v=1613707156\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_DOP.pdf?13531257300286533905\" target=\"_blank\"\u003e\u003cstrong\u003eDeclaration of Performance (DoP)\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_DOP.pdf?13531257300286533905\" target=\"_blank\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_DEC_OF_PERFORMANCE_160x160.jpg?v=1613707212\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_BBA_dc0006d2-f308-4bfd-8730-7a61531028de.pdf?13531257300286533905\" target=\"_blank\"\u003e\u003cstrong\u003eBBA Certificate\u003c\/strong\u003e\u003c\/a\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_BBA_dc0006d2-f308-4bfd-8730-7a61531028de.pdf?13531257300286533905\" target=\"_blank\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2617\/5036\/files\/NEWTON_508_MESH_BBA_160x160.jpg?v=1613707212\"\u003e\u003c\/a\u003e\u003c\/div\u003e","brand":"John Newton \u0026 Co.
