A critical component of any new basement construction is the proper detailing of the head of retaining walls. This detail is often overlooked or improperly executed, leading to costly leaks and significant claims with warranty providers like NHBC.

During the design phase, our waterproofing experts meticulously inspect all areas requiring this detail to ensure full compliance with BS8102:2022 standards. You can rest assured that we assume complete design liability under our £10 million PI cover.

Including this detail at the design stage is essential. If neglected, it can have severe repercussions. Our experienced and certified surveyors will always incorporate this aspect into your quote.

Our skilled technicians have been diligently preparing the head of the retaining wall and applying our PolyM liquid membrane to guarantee no water ingress in this area.
