520 eco Floor

BBALogoCertNo 3010

  • High Drainage Capacity: With a 20mm deep stud profile, 520 eco Floor provides exceptional drainage capacity, ideal for areas at risk of severe water penetration.
  • Sustainable and Durable: Made from 100% recycled materials, this eco-friendly membrane offers a 30-year guarantee and a life expectancy that matches the design life of the building.
  • Chemical and Biological Resistance: Inert and non-polluting, 520 eco Floor is highly resistant to water, alkalies, saline solutions, organic acids, minerals, hydrocarbons, root penetration, bacteria, fungi, and other small organisms.
  • Certified Performance: Supported by BBA Certification Number 94/3010, ensuring reliable and long-lasting waterproofing performance as part of the Newton CDM System, including drainage and pumping systems.

Newton 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 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.

    British Standard 8102:2022

    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).
