About Us

Brilliant basement start with us! We've been installing waterproofing since 2009 and take the time to understand the exact details of every job we do.

Design meets detail

We understand that every job is different. Each project has specific design challenges which need to be fully understood, designed and implemented… all with precision and care.

Our in house design service will lead you to a designed and costed solution quickly. We work in partnership with architects, system manufacturers and clients to ensure we deliver a robust solution which complies with all building regulations. 

Installed perfectly

Correctly installed waterproofing materials are crucial to a successful build. All of our operatives have industry specific training on the products we install. In addition they have CSCS, PASMA, SSSTS. Our designers have CSSW (Certified Surveyors In Structural Waterproofing). 

Combined together, we have a great team focused on delivering a perfect job; safely and on budget.
