Newton CDM 508 Mesh Cavity Drain Membrane – 2m x 20m

8mm Meshed Cavity Drain Basement Wall Membrane. Newton CDM 508 Mesh is a high quality, 8mm meshed cavity drain waterproofing membrane for use within the Newton CDM System, Newton’s internally applied waterproofing system that also includes drainage and pumping systems. A strong polyethylene mesh is thermally welded to the face of the membrane during manufacturing to provide a key for plasters and renders. 

CDM 508 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 508 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.
