Description
Newton CDM 520 eco is a high quality and 100% recycled, 20mm 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.
Key Benefits
Third-party tested for long-term compressive load to ISO 25619-1 (2% compression over 50-years)- Speed of installation
- Made from 100% recycled HDPE
- Provides vapour control and, when used with humidity control systems and is capable of delivering an environment to all levels within a Grade 3 environment to BS 8102:2022
- Resistant to rot, chemically aggressive groundwater, acids and alkalines, efflorescing salts and hydrocarbon contamination
- Product waste can be recycled
Typical Applications
Floor membrane as part of the Newton CDM Type C waterproofing system.
Suitable Substrate
- Concrete raft or slab
- Newton Fibran XPS 500-C closed cell extruded polystyrene insulation
British Standard 8102:2022
The British Standard 8102:2022 Code of Practice for Protection of Below Ground Structures Against Water Ingress is the main design guide for structural waterproofing in the UK.
The Newton CDM System is a maintainable system, so complies with BS 8102 requirements. The standard also specifies that: “a waterproofing specialist should be included as part of the design team so that an integrated waterproofing is created”
Therefore it is our recommendation that the Newton CDM System is installed by a Newton Specialist Contractor (NSBC).
