Newton CDM 520 eco is a high quality and 100% recycled, 20 mm cavity drain floor membrane, for use within the Newton CDM System, our internally applied waterproofing system that also includes drainage and pumping systems.

With its 20 mm deep stud profile, Newton CDM 520 eco is used within the Newton CDM System as a high drainage capacity floor membrane, and is generally specified where it is anticipated that there may be a risk of severe water penetration.

Newton 520 eco is guaranteed against deterioration for 30 years, with a life expectancy of at least the design life of the building (DIN 9001:2000) and is supported by BBA Certification Number 94/3010.

Newton 520 eco is inert and, therefore, non-polluting to drinking water, highly resistant to water, alkalies, saline solutions and organic acids, and not affected by minerals and hydrocarbons. It is also impervious to root penetration, is rot-proof, and resistant to bacteria, fungi and other small organisms.
