Application

  • Suitable for the waterproofing of earth retained walls, vaulted soffits and floors.
  • Existing and new build basements.
  • Wall and floor membrane as part of the Newton CDM Type C waterproofing system.

Description

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.


Features and benefits:

  • Third-party tested for long-term compressive load to ISO 25619-1 (2% compression over 50-years).
  • Does not require extensive and damaging preparation to the wall surface.
  • Speed of installation.
  • Provides vapour control used with humidity control systems, capable of delivering an environment to all levels within a Grade 3 environment to BS 8102: 2022.
  • Independently certified as a barrier to hydrocarbon gases, radon, methane and CO₂.
  • Resistant to rot, chemically aggressive groundwater, acids and alkalines, efflorescing salts and hydrocarbon contamination.
  • Guaranteed against deterioration for 30 years, with a life expectancy of the design life of the building (DIN 9001: 2000), and supported by BBA Certification Number 94/3010. 


Suitable substrates:

Walls:

  • Concrete.
  • Brick.
  • Concrete block.
  • ICF - With special longer fixing plugs.

Soffits:

  • Concrete - To fall.
  • Brick - Arched or vaulted.
