Transform Your Basement Into Usable, Permanently Dry Space
Tanking systems and cavity drain membranes to create genuinely dry, usable basement spaces — whether for a utility room, office, or extra living area.
About Basement Waterproofing
A wet or damp basement is a wasted opportunity. EverDry Damp specialises in BS 8102-compliant basement waterproofing systems that convert damp, unusable cellars into genuinely dry, habitable space. We use two primary approaches: Type A tanking (applied waterproofing systems bonded to the structure) and Type C cavity drain membranes (drainage systems that manage water rather than resist it). The right system depends on the water pressure, construction type, and intended use — we survey every basement before recommending a solution.
Signs You May Need Basement Waterproofing Treatment
- Standing water on basement floor
- Damp or wet walls below ground level
- White crystalline deposits (efflorescence) on basement walls
- Musty smell or visible mould in cellar
- Peeling paint or plaster failure on basement walls
Common Causes
- High external water table pressing against below-ground walls
- Failed or absent original waterproofing on older properties
- Cracked or porous masonry allowing water infiltration
- Settlement cracks in floor slabs
- Blocked or collapsed land drains around foundations
Frequently Asked Questions
What is the difference between tanking and cavity drain membrane?
Tanking (Type A) applies a waterproof coating directly to the structure to resist water pressure. Cavity drain membrane (Type C) accepts that water will enter and manages it to a sump and pump instead. Type C is generally more reliable long-term for habitable spaces.
Can I convert my basement into a bedroom?
Basement conversions into habitable rooms require Building Regulations approval alongside proper waterproofing. We can advise on the waterproofing element and work alongside your architect or builder for the full conversion.
How long does basement waterproofing take?
A standard cellar waterproofing with cavity drain membrane typically takes 3–5 days depending on size. Larger or more complex projects may take longer. We will give you a precise programme before work starts.
