Newton CDM 508R is a high quality, 8mm cavity drain membrane & gas barrier that is heavier and stronger than standard 8mm membranes, and is certified for use as a barrier to ground gases and hydrocarbons. The membrane is installed within the Newton CDM System, our internally applied waterproofing system that also includes drainage and pumping systems.
CDM 508R is suitable for the waterproofing of earth retained walls, vaulted soffits and floors 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 Certification 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. The membrane also holds test data that exhibits its high compressive loading stability.
Newton CDM 508R is independently tested as an effective barrier to radon ground gases, methane, CO2 and hydrocarbons. It is also the chosen membrane for use within our patented combined ground gas and waterproofing system, Newton PAC-500.
