CDM System

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 System is certified to the BES 6001 standard for responsible sourcing, and includes a range of BBA certified cavity drain membranes. 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.
