BS 8102:2009

The British Standard for Below-Ground Waterproofing

The British Standard for below ground waterproofing, BS8102, was revised in 2009 to ensure it provided the most up-to-date standards and requirements for designers and specifiers to follow.

In addition to favouring the use of cavity drain membranes for waterproofing below-ground, for the first time references to radon gas were made throughout the document.

The Code of Practice document now advises that radon should be taken into account when designing any below-ground waterproofing system and that the use of techniques over and above those which provide standard waterproofing should be considered.
