Newton PAC-500

The Newton Cavity Drain Membrane (CDM) System is a maintainable basement waterproofing solution, certified to BES 6001 by BRE Global, ideal for new-build basements and refurbishment projects.

The Four Components of the Newton CDM System

Comprising of four components: Cavity Drain Membranes, Drainage, Pumps and Control Systems, the Newton CDM System complies with the British Standard for Waterproofing and provides a Grade 3 habitable internal environment.

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, 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.
