Newton CDM System (Newton System 500 Cavity Drain Membrane System)

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.

Type C Waterproofing

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 membranes. These membranes, coupled with the bespoke sump and pump configurations, backup systems, telemetry, and ancillary options, make them the most reliable and maintainable waterproofing solution for any habitable space below ground.
