Keeping Your Basement Dry for Good
Structural waterproofing is the foundation of any successful basement conversion. Without the right waterproofing system in place, even the most beautifully finished basement will suffer from damp, mould, and structural damage. At Acorn Basement Conversions, we are specialists in all forms of structural waterproofing, using only the best systems and materials to ensure your basement stays dry for decades.
10-Year Guarantee
All our waterproofing treatments are backed by a comprehensive 10-year guarantee, giving you complete peace of mind.
Our Waterproofing Systems
Tanking
Tanking involves applying a waterproof render or slurry coating directly to the internal walls and floor of your basement. This creates a continuous barrier that prevents water ingress. Tanking is ideal for basements with low to moderate water pressure and is a cost-effective solution for many properties.
Best for: Low to moderate water pressure, solid masonry walls, new builds
Cavity Drain Membranes
A cavity drain membrane (CDM) system manages water rather than blocking it. A studded membrane is fixed to the walls and floor, creating a cavity that channels any water ingress to a drainage channel and sump pump. This is the most widely used and reliable system for existing basements.
Best for: Existing cellars, high water table areas, retrofit projects
Sump & Pump Systems
A sump and pump system collects water that enters the drainage channels and automatically pumps it away from the building. We install high-quality, reliable pump systems with battery backup to ensure your basement stays dry even during power cuts.
Best for: High water table, heavy water ingress, used alongside CDM systemsOur 10-Year Guarantee
We are so confident in the quality of our waterproofing work that we back every treatment with a comprehensive 10-year guarantee. As members of the Basement Waterproofing Association (BWA), our work meets the highest industry standards. You can have complete peace of mind that your investment is protected.
