A high quality cavity drain waterproofing membrane, suitable for the waterproofing of earth retained walls, vaulted soffits and floors.
Newton CDM 508R is a high-quality cavity drain waterproofing membrane that is heavier and stronger than standard 8 mm membranes, and is certified for use as a barrier to ground gases and hydrocarbons. The membrane is installed within the Newton CDM System, an internally applied waterproofing system that also includes drainage and pumping systems.
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 the patented combined ground gas and waterproofing system, Newton PAC-500.
