In internally applied cavity drain membrane installations, fixings are necessary to hold the membrane securely against the wall, but each fixing point must be correctly sealed to prevent water or dampness passing through the penetration and compromising the integrity of the system. The Newton MultiPlug addresses this directly by combining a mechanical fixing plug with a fitted rubber sealing washer, creating a secure and reliable fixing whilst simultaneously protecting the continuity of the waterproofing layer at every point where the membrane is attached to the substrate.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eRubber Sealing Washer Protects Membrane Integrity At Every Fixing Point\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe MultiPlug is installed by drilling a 10mm hole through the centre of a membrane stud and into the retaining wall or masonry substrate behind it. As the plug seats fully into position, the soft sprung rubber washer compresses tightly against the face of the membrane, forming a dependable watertight seal around the fixing point. This is especially important in below-ground waterproofing applications, where cavity drain membranes are used to manage water ingress and direct moisture behind the membrane towards the designed drainage system. A poorly sealed fixing can create a genuine weak point in the overall system, so using a plug specifically designed and tested for use within the Newton membrane system is an important step in protecting the long-term performance and reliability of the completed installation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eThreaded Core Allows Secondary Fixing Without Additional Membrane Penetrations\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eA particularly practical benefit of the Newton MultiPlug is the hole through its core, which is designed to accept 5mm size 10 threaded screws. This thoughtful feature allows secondary fixings to be made into the plug without the need to drill additional holes through the membrane itself, helping preserve the waterproofing layer throughout the internal fitting-out process. Battens, ply board, affixed dry-lining systems, tracking and suitable ancillary products can all be mounted using the existing plug positions, keeping the membrane fully intact. The MultiPlug can also serve as the anchorage point for the CDM Helical MultiPlug Tie where an internal block or brick wall is being constructed in front of the membrane, making it an important component in the wider internal finishing build-up.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eVersatile Application Across Basement Cellar And Structural Waterproofing Projects\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Newton MultiPlug plays an important role not only in securing the membrane to the substrate, but also in supporting the internal finishing build-up across a wide range of project types. It is commonly specified in basement conversions, cellar waterproofing, damp proofing and structural waterproofing projects, where the internal construction must be built out in front of the membrane without compromising its performance. For weaker, friable or low-density substrates such as soft brick, natural stone or certain blockwork types, Newton MultiPlug Pins are available separately and can be inserted into the plug to expand its outer circumference by approximately 2mm, meaningfully increasing anchorage in situations where the masonry may not grip a standard plug reliably without additional mechanical assistance.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eRecommended Fixing Densities For Meshed And Non-Meshed Newton Membranes\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eIndicative fixing densities for Newton MultiPlugs are approximately 15 plugs per square metre at around 250mm centres for meshed membranes, reducing to around 5 plugs per square metre for clear non-meshed membranes. These figures provide a useful starting point for planning material quantities and installation layouts, though the final fixing frequency should always be determined in accordance with the relevant Newton membrane installation instructions and the specific requirements of the project waterproofing specification. Correct fixing density is important for ensuring the membrane remains securely held against the wall across its full extent, particularly in areas subject to water pressure, thermal movement or subsequent loading from internal wall construction. Following the manufacturer’s guidance helps protect both the immediate installation and the long-term performance of the waterproofing system as a whole.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cstyle\u003e\n  .pc-newton-multiplugs-tech-table-wrap {\n    width: 100%;\n    max-width: 100%;\n    overflow-x: auto;\n    -webkit-overflow-scrolling: touch;\n    margin: 24px 0;\n  }\n\n  .pc-newton-multiplugs-tech-table {\n    width: 100%;\n    min-width: 620px;\n    table-layout: fixed;\n    border-collapse: collapse;\n    font-family: inherit;\n    font-size: 16px;\n    line-height: 1.25;\n    color: #111;\n    background: #fff;\n  }\n\n  .pc-newton-multiplugs-tech-table col:nth-child(1) { width: 38%;

for?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs (Newton product reference A1) are specialist fixing plugs designed for use with Newton cavity drain membrane systems. Their primary purpose is to secure Newton wall membranes to retaining structures while maintaining the watertight integrity of the membrane at each fixing point. Each plug measures 10mm in diameter x 57mm long and is supplied with a fitted soft rubber sealing washer. Once hammered into a 10mm drilled hole through a membrane stud and into the wall, the washer compresses against the membrane to form a watertight seal. The plug also accepts 5mm size 10 threaded screws, allowing battens, ply board, wall ties and dry-lining systems to be fixed without creating additional membrane penetrations.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What makes Newton MultiPlugs different from ordinary wall plugs?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs have been specifically manufactured for use with Newton cavity drain membranes, making them fundamentally different from ordinary wall plugs used in standard construction work. A regular wall plug provides mechanical fixity in masonry but creates an unsealed penetration that would allow water or dampness to pass through a waterproofing membrane, compromising the entire system. The Newton MultiPlug addresses this by incorporating a fitted soft rubber sealing washer that compresses tightly against the membrane face when the plug is driven home. This combination of mechanical fixing and integral waterproof seal is critical in below-ground waterproofing applications where every penetration through the membrane represents a potential weak point in the drainage system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Where can Newton MultiPlugs be used in waterproofing and damp proofing installations?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs are designed for a wide range of cavity drain membrane applications. Typical uses include securing Newton CDM wall membranes in basement waterproofing systems, fixing cavity drain membranes in cellar tanking projects, and installing Newtonite membranes in damp proofing applications. The plug is suitable for fixing membranes to brickwork, concrete retaining walls, stonework and blockwork, provided the substrate is sound enough to accept a mechanical fixing. The hollow plug core also allows batten and ply board fixing, dry-lining system support and internal wall tie anchorage using CDM Helical MultiPlug Ties. This broad range of applications makes Newton MultiPlugs an important component across basement conversions, cellar waterproofing, structural waterproofing and general damp proofing refurbishment projects.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) When should Newton MultiPlugs be installed during a cavity drain membrane project?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs should be installed as part of the membrane fixing stage, once the Newton cavity drain membrane has been correctly positioned, levelled and aligned on the wall substrate. Before drilling begins, the masonry background should be confirmed as sound, stable and suitable for mechanical fixings. Any loose, badly damaged or unstable background should be repaired before installation continues. The plugs are installed through the membrane studs during the membrane installation process, not retrospectively after the full system has been assembled. Where internal battens, dry-lining systems or wall ties are required, the MultiPlug core should be used for these secondary fixings rather than drilling additional holes that would create new penetrations through the waterproofing layer.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the main advantages of using Newton MultiPlugs?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs offer a strong combination of practical advantages for cavity drain membrane installations. They have been specifically designed for Newton waterproofing systems, providing a far more suitable fixing solution than standard wall plugs. The fitted rubber sealing washer creates a watertight seal at each fixing point, protecting the continuity of the waterproofing layer. The hollow plug core accepts 5mm size 10 threaded screws, allowing secondary fixings for battens, ply board, wall ties and dry-lining without additional membrane penetrations. Newton MultiPlug Pins are available for weaker substrates where standard grip is insufficient. The plug is compatible with both the Newton CDM System and the Newtonite System, making it genuinely versatile across basement waterproofing, cellar tanking and damp proofing applications.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What technical specifications do Newton MultiPlugs have?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs measure 10mm in diameter by 57mm in length and are designed to be installed into a 10mm drilled hole formed through a membrane stud and into the masonry substrate. Each plug is supplied with a fitted soft rubber sealing washer, which compresses against the membrane face as the plug is driven fully home. The hollow plug core accepts 5mm size 10 threaded screws, allowing secondary fixings into the plug without creating additional membrane penetrations. Where required, Newton MultiPlug Pins can be inserted to expand the outer circumference of the plug by approximately 2mm, improving anchorage in weaker or lower density substrates. The Newton product reference for the MultiPlug is A1.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What fixing density is recommended when installing Newton MultiPlugs?\u003c\/h3\u003e\n\u003cp\u003eA) The recommended fixing density for Newton MultiPlugs depends on the type of Newton membrane being installed. As an indicative guide, approximately 15 plugs per m² at around 250mm centres is recommended for meshed membranes, reducing to approximately 5 plugs per m² for clear non-meshed membranes. These figures reflect the different structural requirements of each membrane type and the additional support that meshed membranes require to remain properly secured to the wall. However, these are indicative figures only. The exact fixing pattern should always follow the relevant Newton membrane installation instructions and the requirements of the intended wall finish, as the project specification and membrane type will determine the final fixing frequency required.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How are Newton MultiPlugs installed correctly?\u003c\/h3\u003e\n\u003cp\u003eA) To install Newton MultiPlugs correctly, first confirm the masonry substrate is sound and the membrane is correctly positioned. Select a membrane stud as the fixing location and drill a 10mm hole through the stud centre and into the wall to a suitable depth. Push the plug into the hole with the rubber sealing washer positioned against the membrane face, ensuring the plug sits squarely before hammering begins. Drive the plug fully home using a hammer or club hammer until it is completely seated. As it seats, the rubber washer compresses against the membrane to form the watertight seal. Check that the plug is secure and the washer is compressed evenly, with the plug fully home and not loose, proud or twisted.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What should be done when Newton MultiPlugs are used in weak or friable substrates?\u003c\/h3\u003e\n\u003cp\u003eA) When Newton MultiPlugs are used in weak, friable or low-density substrates such as soft brick, stone or certain blockwork types, standard fixing may not achieve sufficient anchorage. In these situations, Newton MultiPlug Pins should be used to improve grip. The pins are sold separately and are inserted into the plug after installation, expanding the outer circumference of the plug by approximately 2mm. This increased diameter improves contact between the plug and the surrounding masonry, providing better anchorage where the substrate does not grip a standard plug reliably. It is important to identify potential substrate weakness before installation begins so that pins can be prepared in advance, rather than attempting to address poor fixing strength retrospectively once the membrane system is in place.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How do Newton MultiPlugs allow secondary fixings without extra membrane penetrations?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs allow secondary fixings through the hollow core at the centre of each installed plug. Once the plug is fully seated and the rubber washer has sealed the membrane penetration, 5mm size 10 threaded screws can be driven directly into the plug core. This means that battens, ply board, wall ties, dry-lining tracks and compatible ancillary products can all be mounted to the wall without drilling any additional holes through the cavity drain membrane. Maintaining the integrity of the membrane at this stage is critical, as each unnecessary penetration represents a potential point of failure in the waterproofing or damp proofing system. Using the MultiPlug core for secondary fixings is therefore an important part of protecting the long-term performance of the installation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton MultiPlugs be used with both the Newton CDM System and the Newtonite System?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton MultiPlugs are compatible with both the Newton CDM System for basement waterproofing and the Newtonite System for damp proofing, making them a consistent fixing solution across the Newton membrane product range. In CDM basement waterproofing installations, the plugs secure the cavity drain wall membrane to the retaining structure while maintaining the sealed fixing points required in below-ground waterproofing conditions. In Newtonite damp proofing installations, the plugs perform the same function of holding the membrane firmly against the internal wall without compromising the damp-resistant layer. The MultiPlug can also be used as the anchorage point for CDM Helical MultiPlug Ties where an internal block or brick lining wall is being constructed in front of the membrane.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What types of substrate are Newton MultiPlugs suitable for?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs are suitable for fixing Newton cavity drain membranes to a range of masonry substrates, provided the background is sound enough to accept a mechanical fixing. Suitable substrates include brickwork, concrete retaining walls, stonework and blockwork. Concrete walls are particularly well suited to the standard plug, as the dense material provides reliable anchorage for the 10mm fixing. For brickwork and blockwork, the substrate condition should be checked before installation, as older, softer or more porous masonry may require Newton MultiPlug Pins to achieve adequate fixing strength. For stonework, the plug can be used in many stone types, with pins again available where the stone is weaker or more irregular. Any loose or badly damaged background should be repaired before installation begins.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What role do Newton MultiPlugs play in supporting internal finishes in waterproofed areas?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs play an important role beyond simply fixing the membrane to the wall. Because the hollow core accepts 5mm size 10 threaded screws, the plugs provide ready-made anchor points for the internal finishing build-up in basement conversions, cellar waterproofing projects and damp proofing refurbishments. Timber battens, ply board and compatible dry-lining systems can all be fixed into the plug cores without introducing additional penetrations through the waterproofing layer. The MultiPlug can also act as the anchorage point for CDM Helical MultiPlug Ties where a new internal block or brick lining wall is being built in front of the membrane. This dual function makes Newton MultiPlugs a critical component in the overall construction detail of finished waterproofed or damp proofed internal spaces.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Are there any practical tips for getting the best results when installing Newton MultiPlugs?\u003c\/h3\u003e\n\u003cp\u003eA) For the best results when installing Newton MultiPlugs, plan the fixing layout carefully before drilling begins and always fix through the centre of a membrane stud to ensure the rubber washer seats correctly. Keep the drill straight during hole formation to avoid tearing the membrane or damaging adjacent studs. Position the plug squarely in the hole before hammering to ensure the washer compresses evenly. Check each plug after installation to confirm it is fully seated, secure and not proud of the membrane surface. Where substrate weakness is identified, prepare Newton MultiPlug Pins before starting work rather than discovering the issue mid-installation. For secondary fixings, always use the plug core with 5mm size 10 screws rather than drilling new holes through the membrane.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the limitations of Newton MultiPlugs?\u003c\/h3\u003e\n\u003cp\u003eA) Newton MultiPlugs have several important limitations to be aware of. They are specifically designed for Newton cavity drain membrane systems and are not general-purpose wall plugs suitable for other fixing applications. The plug relies on a sound masonry substrate to achieve a secure mechanical fixing, so loose, badly damaged or highly friable backgrounds must be repaired or supplemented with Newton MultiPlug Pins before installation. The rubber washer seal depends on the plug being fully and correctly seated, so partial installation or misalignment can compromise waterproofing integrity at the fixing point. The plug only accepts 5mm size 10 threaded screws for secondary fixings, so heavier loads or alternative fixing types must be considered carefully against the system specification and the Newton installation guidance.\u003c\/p\u003e","brand":"John Newton \u0026 Co.
