A damp or leaking basement can quickly become unusable and cause damage to your home if left untreated. Roof Crest provides professional basement tanking across London, making below ground spaces dry and usable.
BASEMENT TANKING
Expert Basement Tanking Solutions
Basements and cellars are naturally prone to water ingress due to their position below ground, and without the right waterproofing, damp and leaks can make the space unusable and put the wider structure at risk.
At Roof Crest, we assess the cause and severity of the problem before recommending the right tanking system, whether that’s a cementitious tanking slurry, a cavity drain membrane system, or a combination of both. We’ll explain exactly what’s needed and why, so the space stays dry long after the work is done.

What is basement tanking?
Basement tanking is a waterproofing process that prevents water from entering a below ground space, using methods such as cementitious slurry coatings or cavity drain membrane systems.
How do I know if my basement needs tanking?
Signs include damp patches, water stains, a musty smell, mould growth, or standing water. If you’re noticing any of these, it’s worth getting the space inspected.
What's the difference between tanking systems?
Cementitious tanking involves applying a waterproof coating directly to the walls and floor, while cavity drain membrane systems manage water by channelling it away rather than blocking it entirely. We’ll recommend the right approach based on your property and how you plan to use the space.
How long does the tanking process take?
This depends on the size of the space and the system used. We’ll give you a realistic timeframe once we’ve assessed the property.
How much does basement tanking cost?
Cost depends on the size of the space, the extent of the water ingress, and the system required. We’ll give you a fixed, no obligation quote after a free survey.
Can I use my basement for storage or living space after tanking?
Yes, once tanked correctly, the space can typically be used for storage, a home office, or even a habitable room, depending on other factors like ventilation and building regulations.
