Newton Waterproofing Membranes (System 500) are 'Type C' waterproofing mambranes that includes BBA Certified membranes, drainage channels, pumping systems and pumping ancillaries specifically designed for waterproofing earth retaining structures against water from the ground.
Newton® Waterproofing Membranes work by creating a depressurisation space using the studded Newton® Membrane on the internal surface and drainage channels at the known and / or designed points of weakness in the structure.
The Waterproofing System includes a range of tapes, fixing plugs and sealants.
Newton® Waterproofing Membranes also provide protection when used in earth retaining scenarios for those substrates contaminated by carbon deposits, salts, fertilizers etc., and can also offer protection in high radon and methane gas locations.
Newton® Waterproofing Membranes do not seek to hold back water pressure. Water ingress is controlled and managed by the depressurisation spaces created by the system. The membranes do more than provide a dry inner skin to separate the wet substrate and dry interior, with the studs acting more like stilts to allow for this natural movement of water rather than a pressure-resisting barrier. The draining of the water away from the system is therefore vitally important, and if designed correctly is the safest method of waterproofing available.
The Newton® CDM (Cavity Drain Membrane) System comprises a range of specifically designed complementary products. The products that make the waterproofing system are listed below, together with a brief explanation of each product use:
Newton® 508R: A High Density Polyethylene (HDPE) Cavity Drain Membrane with 8mm deep conical studs for lining walls, soffits and floors. Newton® 508 is certified for use as a gas barrier and is the membrane to be used to both walls and floors with the Newton® PAC Gas System.
Newton® 508: Lighter weight version of Newton® 508R that is suitable for walls only. It is not suitable for use with gas protection systems or for use as the floor membrane.
Newton® 508 Mesh: High Density Polyethylene (HDPE) Cavity Drain Membrane with 8mm deep conical studs for walls and soffits. The membrane has nylon mesh thermally welded to the face of the membrane to act as a key for plasters, renders and as a base for dot & dab plasterboard.
Newton® 503: High Density Polyethylene (HDPE) Membrane with 3mm deep studs for floors. Newton® 503 is ideal floor membrane to a Newton® Waterproofing System where 20mm or even 8mm studs cause problems with floor height or where a thinner membrane than 508 is required to the walls.
Newton® 520: A fully recycled High Density Polyethylene (HDPE) Cavity Drain Membrane with 20mm deep conical studs for floors. Newton® 520 is used where it is expected that water may ingress the structure through slab defects and a greater drainage performance is required.
Newton® Condensation Strip: Forms an 8mm gap between the Basedrain perimeter drainage channel and wall membrane so that if condensation should form, it will be collected by the Basedrain and not pool on the floor, damaging finishes.
Newton® 906 Lime Inhibitor: A surface applied treatment prevents the leaching of free lime from out of the concrete. We do not stock Newton® 906 Lime Inhibitor, however we can offer our own Platinum Lime Inhibitor which works exactly the same.
Newton® Waterseal Rope: Butyl rope in a 10mm bead used for jointing membranes when a flange seal is not possible.
Newton® Waterseal Tape: Butyl tape used for jointing membranes along the flange.
Newton® MultiPlug: The Newton® MultiPlug has been developed to provide an improved fixing product over the Nuseal Plugs. The MultiPlug has been engineered to give a better fix in questionable substrate, and have the added benefit of having a rubber sealing grommet supplied with the plug.
If the fix is not as good as hoped, the MultiPlug Pin (Purchased Separately) is inserted into the plug that expands its outer circumference by nearly 2mm to tighten the plug into the substrate. The MultiPlug is pre-drilled to accept a size 10 (5mm) self-tapping screw for the fixing of battens or other dry-lining systems. Requires a 10mm drilled hole for insertion.
Newton® NuSeal Plug: The Newton® NuSeal Plug is used with Newton® Waterseal Rope to provide a watertight seal between the plug and the membrane and is the plug used for fixing membranes to vaulted soffits. The NuSeal Plug is pre-drilled to accept a size 12 (6mm) self-tapping screw for the fixing of battens or other dry-lining systems. Requires a 11mm drilled hole for insertion.
Newton® Overtape: Black PVC backed one-sided tape used for connecting floor membranes to the Basedrain up-stand, Floor membranes to wall membranes, sealing abutting joints to Newton® 503 and for repairs and reveal details.
Newton® Mesh Tape: One-sided fabric tape used for over taping joints to Newton 503 Mesh or Newton 508 Mesh which have already sealed with Newton Waterseral Rope or Newton Waterseal Tape as a surface key for plastering or rendering. We do not currently stock Newton Mesh Tape, however our own brand Platinum Mesh Tape can be used in these applications as an alternative.
Newton® Basedrain & Floordrain: White PVC drainage conduit designed to drain System 500 at the wall / floor junction and at construction joints to the floor. Has 18mm holes every 100mm along its length to receive water pressure at the vulnerable junction of wall and floor and at construction joints within the floor. Has fittings to allow for connection to the Newton® Titan-Pro Sump Chambers and to 63mm O/D pipe for further connection to 110mm drainage pipe for where safe gravity removal of water is possible, as well as Jetting Eyes, T Pieces and 90° Swept Corners.
Newton® Fibran XPS 500-C - Insulated Spacer: Sheets of XPS insulation form a 50mm insulated spacer adjacent to the Basedrain and Floordrain drainage channels within the Newton® CDM waterproofing system. The insulation boards are rated at 500kPa and feature specifically designed slots to the underside of the boards, that in combination with the perimeter and spine drainage channels of Newton® System 500 form a fully drained supporting spacer below the floor drainage membrane.
