    BS 8102:2009

    BS 8102:2009

    The British Standard 8102:2009 Code of Practice for Protection of Below Ground Structures Against Water From the Ground is the main design guide for structural waterproofing in the UK.

    Newton System 500 is a maintainable system, so complies with BS8102 requirements. BS8102 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 Newton System 500 is installed by a Newton Specialist Basement Contractor (NSBC).
