Structural Waterproofing

No matter what your structural waterproofing requirements, we offer specialist advice when you need it most.

Structural Waterproofing Experts

We’re fully qualified to design, supply and install structural waterproofing systems, from the roof down to basement level, for both existing buildings and new build structures. All our work is carried out in accordance with the BS 8102:2022 Code of Practice, established to protect structures against ground water. And, as our surveyors are CSSW qualified and listed on the Waterproofing Design Register, and we hold full professional indemnity insurance, we give you peace of mind.
