    BS 8102:2022

    BS 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).
