Is your structural waterproofing design robust enough for a warranty?

Are your structural waterproofing designs based on a waterproofing risk assessment that has been produced by a suitably qualified specialist? Have you appointed a waterproofing specialist at an early stage of the system design to ensure it is suitably integrated with the overall design of the building? Is your waterproofing expert qualified to CSSW structural waterproofing surveyor standard? If the answer is no to any of these questions then a building insurance company is unlikely to issue you with a warranty.

The increase in the provision of residential basements, the development of new types of waterproofing system and the growing number of claims being made following the failure of structural waterproofing systems were all key drivers for recent changes in industry and insurance company standards – and the reluctance of insurance companies to issue warranties if these new recommendations are not followed.

BS 8102: 2009 (Code of practice for protection of below ground structures against water from the ground) and NHBC waterproofing standards both now include recommendations that any waterproofing system designs are based upon a risk assessment that is appropriate for the property and its intended use, and that the risk assessment is produced by someone who is suitably qualified.

INK Technical Services was established to help housebuilders, architects and other specifiers meet the standards’ requirements so insurance companies are satisfied that a robust waterproofing system is in place. The INK team represents nearly 100 years of structural waterproofing experience and includes CSSW qualified structural waterproofing surveyors. In addition to the production of waterproofing risk assessments, INK Technical Services offers a waterproofing design service; site inspections; reports on failed systems and proposals for remedial measures and approved contractor referrals.
