Description
Description
Newton CDM 508 is the cornerstone of the Newton CDM System, a versatile 8mm-stud cavity drain membrane designed for internal waterproofing of below-ground structures. It works by creating an air gap between the structure and the internal wall or floor, allowing water to depressurize and safely drain away to a sump and pump system. Available in both 500g/m² and 700g/m² variants, it provides a flexible solution for walls, floors, and vaulted soffits. BBA-certified and guaranteed for 30 years, it is rot-proof, chemically inert, and capable of creating a dry Grade 3 internal environment even in the most challenging basement conditions.
Benefits
- Rapid installation with minimal surface preparation compared to traditional tanking methods
- BBA certified (22/6357) with a life expectancy equal to the design life of the structure
- Highly resistant to aggressive groundwater, alkalines, saline solutions, and organic acids
- Creates a maintainable "Type C" waterproofing system in compliance with BS 8102:2022
- Non-polluting and safe for use in various residential and commercial environments
