Cavity Drain Waterproofing System for Waterproofing of Existing and New-Build Basements - Newton CDM - Cavity Drain Waterproofing
Verified by manufacturer 21 hours ago
The Newton Cavity Drain Membrane (CDM) System is a maintainable basement waterproofing solution, compliant with BS 8102:2022 and ideal for new-build basements and refurbishment projects.
Application
The Newton CDM System is a comprehensive Type C waterproofing system and will usually be suggested as one of the forms of waterproofing to provide superior levels of protection against water ingress and where a completely dry internal environment is required.
This maintainable basement waterproofing solution is ideal for both new-build basements and refurbishment projects. The system comprises of BBA approved cavity drain membranes, drainage conduits, sump chambers, pumps, and associated control and telemetry systems.
British Standard 8102:2022 defines Type C waterproofing as “drained protection” where water leaking through the structure is accepted into voids and air spaces, created by cavity drain membranes that are strategically placed to the inside of the structure, depressurising the incoming water and safely removing it from the property.
A combination of our decades of basement waterproofing experience with our industry-leading products, the Newton CDM Cavity Drainage System includes a range of BBA certified cavity drainage membrane.
These membranes, coupled with the bespoke sump and pump configurations, backup systems, telemetry and ancillary options, makes it the most reliable and maintainable waterproofing solution for any habitable space below ground.
Description
Cavity Drain Membranes and Drainage
Cavity drain membrane (CDM) systems are a maintainable, internal basement waterproofing solution, suitable for protecting below-ground environments against water that has penetrated through the structure. CDM Systems are known as ‘Type C’ waterproofing in British Standard 8102:2022 and are ideal for new-build, refurbishment and historic/listed projects.
Known as the most failsafe form of waterproofing, the cavity drain membranes capture ingressing water at the point of ingress, and then the CDM drainage system manages and directs the water to an integral pumping system or drainage outlet for safe removal.
The Newton PAC-500 System also provides a combined CDM waterproofing and gas proofing system for below-ground spaces that are at risk from ground gases.
Pumps and Control Systems
Once the water has been captured by the cavity drain membranes and drainage channels, it needs to be safely removed. The Titan-Pro is a packaged sump chamber and pump system designed specifically to be used with the Newton CDM System. Compatible with a variety of Newton pumps, it is ideal for almost any cavity drain waterproofing system.
Cavity Drain System Ancillary Products
The Newton CDM System requires a number of specialist ancillary products that are critical for correct installation. At Newton, we supply the full range of ancillary items that are used in conjunction with our cavity drain membranes, drainage and pumping systems.
