Description
BBA certified, 8mm meshed cavity drain membrane for basements – Suitable for use internally below the ground to retaining walls and vaulted soffits.
Newton CDM 508 Mesh Membrane is the most commonly used meshed membrane within our Newton CDM System that includes Newton drainage and pumping systems.
Newton CDM 508 Mesh Membrane is guaranteed against deterioration for 30 years, with a life expectancy of at least 50 years (DIN 9001:2000) and is supported by BBA Certification Number 94/3010.
Benefits
- BBA Certified as a waterproofing membrane as part of the Newton CDM System
- Does not require extensive and damaging preparation to the wall surface
- Polyethylene netting is ‘welded’ to the surface of the membrane during the manufacturing process producing an incredibly well bonded surface mesh
- Superb ‘key’ for renders, plasters or for Dot & Dab Plasterboard
- Waterproofing that is guaranteed to work when used as part of our System 500 installed by a Newton Specialist Basement Contractor
Applications
- As a damp-proof base for renders, plasters or dot & dab plasterboard within the Newton CDM System
- Areas where space is limited such as stairways
- A waterproof base for renders, plasters or dot & dab plasterboard
- As a render base to external areas of the waterproofing scheme such as light-well walls.
- Vaulted soffits or curved walls where a dry-lining frame may not be appropriate
- CDM 508 Mesh Membrane (M3) is supplied in rolls of 2m x 20m giving a total of 40m2
BS 8102:2022
The British Standard 8102:2022 Code of Practice for Protection of Below Ground Structures Against Water Ingress is the main design guide for structural waterproofing in the UK.
The Newton CDM System is a maintainable system, so complies with BS 8102 requirements. The standard also specifies that: “a waterproofing specialist should be included as part of the design team so that an integrated waterproofing is created”
Therefore it is our recommendation that the Newton CDM System is installed by a Newton Specialist Contractor (NSBC).

Newton CDM System - Overview
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.
