Basement Waterproofing Design to BS 8102 – 2009, Code Of Practice

For the protection of below ground structures against water from the ground. It’s critically important that the design team work with this document in mind at all times. As specialist basement waterproofing contractors we help to ensure that your Basement Waterproofing Design meets the overall requirements of BS8102 – 2009.

Recently Building Insurance Guarantee Schemes NHBC and Premier Guarantee have identified that BS8102 is a critical design document when considering basement construction. At the same time they have stipulated that the Waterproofing Design Specialist must carry the CCSW (Certificated Surveyor in Structural Waterproofing) Qualification. Pure Basement Systems’ surveyor has the relevant qualifications (CSSW) to provide you with the required design specification.
