Its bead format allows the material to be shaped around fixing plugs, pipe penetrations, protrusions, corners, irregular substrate details and membrane interruptions. This makes it especially valuable where the continuity of the waterproof layer needs to be maintained across difficult or awkward areas within the cavity drain membrane system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003ePermanently Flexible 10mm Butyl Bead For Watertight Sealing\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eManufactured from a high quality butyl rubber compound, Newton CDM Rope is extruded into a continuous 10mm diameter bead. Butyl rubber is widely used in below-ground waterproofing because it offers strong water resistance, reliable adhesion, flexibility and long-term durability in damp environments. The rope remains tacky and permanently flexible, allowing it to bed into small surface irregularities and maintain close contact with both the membrane and the fixing or service detail. When compressed within the waterproofing detail, the butyl forms a watertight seal that helps prevent water, dampness and moisture from tracking through membrane penetrations, interruptions or poorly sealed junctions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(88, 88, 88);\"\u003eReliable Sealing Around Fixings, Joints And Service Penetrations\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eNewton CDM Rope has three main uses within waterproof membrane detailing: sealing membrane fixings, supporting difficult membrane joints and forming watertight details around penetrations.

System\u003c\/strong\u003e\u003c\/a\u003e. Unlike flat jointing tapes, it is a flexible 10mm diameter butyl rubber bead that can be cut, shaped, wrapped and compressed by hand. This makes it especially useful where a standard tape cannot sit flat or make full contact, such as around pipes, plugs, protrusions, vaulted ceilings, brick arches and sloping soffits. When compressed, Newton CDM Rope helps seal gaps and maintain waterproofing continuity around details that would otherwise be difficult to protect properly.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How does Newton CDM Rope work?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM Rope works by compression. The butyl rope is positioned around the fixing, pipe, joint or detailing point, then compressed by the plug, membrane or adjoining waterproofing element. Because it remains flexible and tacky, it beds into small surface irregularities and forms close contact with the membrane and surrounding detail. This creates a watertight seal that helps prevent water, dampness or moisture from tracking through penetrations, gaps or awkward junctions. Its 10mm solid bead format allows the installer to use exactly the amount needed, shaping it into rings, strips or packed sections depending on the detail. Correct compression is essential for reliable sealing performance.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Where should Newton CDM Rope be used?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM Rope should be used where a waterproof membrane detail cannot be sealed reliably with flat tape alone. Typical uses include fixing plug seals, service penetrations, pipes, cables, conduits, protrusions, irregular junctions, membrane cut-outs and awkward shaped areas. It is particularly useful on vaulted ceilings, brick arches, sloping soffits and overhead membrane installations where conventional sealing washers may not sit evenly against the membrane. It can also be used on non-standard membrane joints where a flange joint or stud-into-stud lap has not been formed. Its role is to help maintain waterproofing continuity across complex details within Newton CDM basement and cavity drain membrane installations.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Can Newton CDM Rope be used to seal membrane fixing plugs?\u003c\/h3\u003e\n\u003cp\u003eA) Yes, Newton CDM Rope is commonly used to seal membrane fixing plugs within Newton cavity drain membrane systems. A small ring of rope can be wrapped around the head or neck of compatible fixings such as \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-cdm-nuseal-plugs-vaulted-ceiling-membrane-fixing-a2\" target=\"_blank\"\u003e\u003cstrong\u003eNewton NuSeal Plugs\u003c\/strong\u003e\u003c\/a\u003e or \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-newtonite-mesh-plugs-damp-proof-membrane-fixing\" target=\"_blank\"\u003e\u003cstrong\u003eNewtonite Mesh Plugs\u003c\/strong\u003e\u003c\/a\u003e before the plug is driven home. As the fixing is tightened or hammered into position, the butyl compresses between the plug and the membrane, forming a waterproof grommet around the penetration. This is especially useful where a washer may not seat correctly, such as overhead fixing points, vaulted ceilings, brick arches or sloping soffits. The rope should be compressed firmly to create a complete seal.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) Is Newton CDM Rope suitable for pipes and service penetrations?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM Rope is well suited to sealing around pipes, cables, conduits and other service penetrations passing through waterproof membranes. These details are often difficult to seal with tape alone because the membrane has to be cut around a three-dimensional object, leaving an irregular gap or edge. The rope can be shaped by hand, wrapped around the service and packed into the gap to create a compressed butyl seal. This helps keep the waterproofing layer continuous around the interruption. For best results, the membrane and service surface should be clean and dry, and the rope should be pressed firmly into place so it maintains full contact around the penetration.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) How is Newton CDM Rope different from Newton CDM Joint Tape?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM Rope and \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-cdm-joint-tape-double-sided-butyl-membrane-tape\" target=\"_blank\"\u003e\u003cstrong\u003eNewton CDM Joint Tape\u003c\/strong\u003e\u003c\/a\u003e are used for different sealing details within the \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/collections\/newton-waterproofing-membranes\" target=\"_blank\"\u003e\u003cstrong\u003eNewton CDM Waterproof Membrane System\u003c\/strong\u003e\u003c\/a\u003e. \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-cdm-joint-tape-double-sided-butyl-membrane-tape\" target=\"_blank\"\u003e\u003cstrong\u003eNewton CDM Joint Tape\u003c\/strong\u003e\u003c\/a\u003e is a flat double-sided tape used for linear sheet-to-sheet joints, such as membrane overlaps, flanges and stud-into-stud laps. Newton CDM Rope is a 10mm diameter butyl bead used for three-dimensional or irregular details where flat tape cannot sit properly. This includes fixing plugs, pipes, protrusions, vaulted ceilings, sloping soffits and non-standard joints. In many installations, both products are used together. Joint Tape handles the clean, flat membrane lap, while Newton CDM Rope seals the awkward areas that need a shaped, compressible bead.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What size is Newton CDM Rope supplied in?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM Rope is supplied as a 10mm diameter solid butyl rubber bead in 4.75m rolls. The bead format is important because it allows the installer to cut off only the amount required for each fixing, penetration or detailing point. A short length can be wrapped into a ring around a fixing plug, while longer lengths can be used along awkward joints, shaped membrane cuts or service penetrations. The 10mm diameter provides enough material to compress and fill irregular gaps, while still being manageable by hand on site. This controlled format helps reduce waste and makes the product adaptable for varied basement waterproofing details.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eQ) What are the main limitations of Newton CDM Rope?\u003c\/h3\u003e\n\u003cp\u003eA) Newton CDM Rope should not be treated as a substitute for correct membrane installation, proper fixing, good joint design or suitable use of \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-cdm-joint-tape-double-sided-butyl-membrane-tape\" target=\"_blank\"\u003e\u003cstrong\u003eNewton CDM Joint Tape\u003c\/strong\u003e\u003c\/a\u003e and \u003ca href=\"https:\/\/www.platinumchemicals.co.uk\/products\/newton-cdm-overtape-butyl-membrane-sealing-corner-tape\" target=\"_blank\"\u003e\u003cstrong\u003eNewton CDM Overtape\u003c\/strong\u003e\u003c\/a\u003e where those products are required.
