In the early 2000s, tighter regulations and improved waterproofing systems let to a rise in popularity of basement conversions and developments in the UK. The use of cavity drain membranes gained traction due to their accessibility for repair and in case of issues, becoming standard practice in the construction industry. A significant court case, Outwig Construction v. Thomas Weatherald, played a pivotal role in shaping British standards and regulations for sub-structural works.

Waterproofing A Structure

When selecting waterproofing in today's market, care must be taken to look at all implications of issues surrounding the property. The popularity of cavity drain membranes is attributed to their accessibility for repairs. The choice of waterproofing method depends on the required level of protection, as outlined in BS: 8102:(2009). 'Type A' applied/barriers can be used alone or combined with 'Type C' system for habitable spaces, however if some dampness may be tolerated then the use of 'Type A' applied product could be relied upon. Not every situation requires a complete 'Type C' internal cavity drainage system.
