BBALogoCertNo 3010Newton 508 eco Floor is a high quality 8mm recycled cavity drain floor membrane, for use within the Newton CDM System, our internally applied waterproofing system that also includes drainage and pumping systems.

Designed with more studs per square metre to deliver higher compressive resistance than standard cavity drain membranes whilst putting less load on the substrate, Newton 508 eco Floor is best suited for floor installations as part of a comprehensive CDM waterproofing system.

Newton 508 eco Floor 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 Certificate Number 94/3010.

508 eco Floor is inert and non-polluting to drinking water, 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.

Newton 508 eco Floor is also independently tested as an effective barrier to radon ground gases, and is used within our patented combined ground gas and waterproofing system, Newton PAC-500.

    Typical Applications

    Typical Applications

    Floor membrane as part of the Newton CDM Type C waterproofing system.

    Suitable Substrate – Floor

    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).
