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

CDM 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.

CDM 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 CDM 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.

Features and benefits:

Third-party tested for long-term compressive load to ISO 25619-1 (2% compression over 50-years).
Speed of installation.
Provides vapour control used with humidity control systems, capable of delivering an environment to all levels within a Grade 3 environment to BS 8102:2022.
Independently certified as a barrier to hydrocarbon gases and radon.
Resistant to rot, chemically aggressive groundwater, acids and alkalines, efflorescing salts and hydrocarbon contamination.
Does not require extensive and damaging preparation to the wall surface.
