CDM 503 Mesh Membrane

BBALogoCertNo-22_6357Newton 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.

    Typical Applications

    Typical Applications

    Walls, vaults, and tunnels as part of the Newton CDM System for below ground waterproofing applications.

    British Standard 8102:2022

    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).
