Trade body spreads the message on successful structural waterproofing to housebuilder audience

National trade body The Property Care Association (PCA) is taking part in an NHBC roadshow to highlight the importance of an expert approach to structural waterproofing projects.

The PCA’s chief executive, Stephen Hodgson, has been asked by NHBC to be part of the speaker programme for their UK-wide ‘Building for Tomorrow’ programme.

As part of the NHBC event, which this year focuses on the route to quality, Mr Hodgson is talking to those in the housebuilding sector on the subject of waterproofing below ground structures.

The PCA’s involvement in the Building for Tomorrow programme – which started in February and runs until April at nine locations nationwide – is part of the association’s bid to support architects and construction professionals through structural waterproofing projects.

A significant element of this was the PCA’s assistance to the NHBC in the development of Chapter 5.4, their revised construction standard for waterproofing basements and other below ground structures, which was launched in 2014. This new section was produced in response to an NHBC report, published in 2013, which revealed claims on basements since 2005 had cost the industry a total of nearly £21 million – and affected nearly 890 homes.

The PCA also offers a range of services to support professionalism in this specialised area.

This includes the PCA’s register of Waterproofing Design Specialists, a pool of vetted and approved professionals with specialist knowledge and qualifications in structural waterproofing who are able to assist in the design and planning of projects involving underground waterproofing.

The trade body also oversees the award of the industry recognised qualification, Certificated Surveyor in Structural Waterproofing (CSSW), attainment of which is one of the requirements for being able to join the PCA’s register of Waterproofing Design Specialists.

Steve Hodgson said:

“It is vital that the design of below ground waterproofing is tackled by specialists who understand ground conditions, the challenges of the site and the complexity of the build, as well as considering the final performance requirements of the underground space.

“Basement waterproofing undertaken by trained and qualified PCA members is far less likely to fail than systems installed by those with little specialist training and often limited understanding of structural waterproofing.

“The construction teams applying, installing and building the underground space must also be fully aware of the critical nature of what they are doing, the importance of accuracy and the implications of any defects and errors.

“It is an important message to get across and we are grateful to the NHBC for providing a platform to deliver it nationwide.”
