A wet or damp basement is wasted space — and a source of ongoing structural damage. Whether you have an existing basement that floods, a cellar suffering from persistent damp, or you're converting a below-ground space for habitable use, professional waterproofing is the essential foundation for any below-ground project.
Below-ground structures are subject to hydrostatic pressure — the constant force of groundwater pressing against and through the surrounding masonry. Unlike above-ground damp, this pressure means water will find any crack, joint, or weak point and force its way through.
Standard damp proofing methods are not designed for this environment. Below-ground waterproofing requires specialist systems rated to withstand hydrostatic pressure.
A rigid, cement-based waterproofing system applied directly to the internal faces of walls and floors, bonding chemically with the masonry to form a waterproof barrier. Suitable for walls in good structural condition and where the structure itself can resist hydrostatic pressure.
A drainage membrane lines the internal walls and floor, channelling any water that penetrates into a perimeter drain and sump pump system. Rather than trying to stop water, it manages and removes it — making it highly effective in situations of significant water ingress and a popular choice for habitable conversions.
The right system depends on the structure, severity of water ingress, and intended use of the space. Our surveys assess all of these factors and recommend the most appropriate and cost-effective solution.
A damp basement left untreated causes progressive damage to the entire structure above it — affecting ground floor timbers, internal walls, and foundations. If you're planning a conversion, getting the waterproofing right from the start is far less expensive than remediating a failed system later.
