Description
Newton CDM 503 Mesh is a high quality, BBA certified, 3mm meshed cavity drain waterproofing membrane for use within the Newton CDM System, our internally applied waterproofing system that also includes drainage and pumping systems. The strong polyethylene mesh is thermally welded to the face of the membrane during manufacturing to provide a key for plasters and renders.
CDM 503 Mesh is suitable for the waterproofing of earth retained walls and vaulted soffits and is guaranteed against deterioration for 30 years, with a life expectancy of the design life of the building (DIN 9001:2000), and supported by BBA Agrément Certificate 22/6357.
CDM 503 Mesh is inert and non-polluting to drinking water, highly resistant to water, alkalines, saline solutions and organic acids, and not affected by minerals and hydrocarbons. It is also rot-proof, and resistant to bacteria, fungi and small organisms.
Key Benefits
- Does not require extensive and damaging preparation to the wall surface
- Speed of installation
- Capable of delivering an environment to all levels within a Grade 3 environment to BS 8102:2022
- 3mm deep for applications where space is tight
- Meshed surface for application of plasters/renders
Typical Applications
Walls, vaults, and tunnels as part of the Newton CDM System for below ground waterproofing applications.
British Standard 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).
