The BSI Kitemark™ is one of the most recognised symbols of quality and safety and offers true value to consumers, businesses and procurement practices.
The BSI run a Kitemark scheme for Flood Protection & Waterproofing Materials

BSI Kitemark for Flood Protection (TM)
When safety matters most choose the BSI Kitemark for Flood Protection products.
The Environment Agency supports the BSI Kitemark scheme for Flood Protection products which demonstrates that products have been independently tested and proved fit for purpose.
The BSI Kitemark for Flood Protection products is based on the publically available specification known as PAS1188. In 2014 a new version of this specification was published and all products now undergoing testing will be tested against the 2014 version which has a significant reduction in the allowable leakage rates compared to the previous version.
All flood prevention products that have a BSI Kitemark are independently witness tested by BSI both at initial type testing stage and then on an on-going basis (typically once or twice a year). This helps to maintain the on-going quality and performance of the products; when it matters most you can trust the BSI Kitemark.
