Newton 520 eco is a cavity drain waterproofing membrane made from recycled High Density Polyethylene (HDPE). It is one of the main constituent parts of Newton CDM System 500, our BBA Certified, ‘Type C’ cavity drain system, used for waterproofing of floors within earth retained structures.
 
The cavity drain system typically includes drainage channels sited below the membrane for increased drainage capacity. With its 20 mm deep stud profile, Newton 520 eco is 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 hydro-carbons. It is also impervious to root penetration, is rot-proof, and resistant to bacteria, fungi and other small organisms.
