Basement Tanking in Tunbridge Wells
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Getting basement tanking right in Tunbridge Wells depends far more on the substrate and the exposure than on the product name.
Most of what we see around Tunbridge Wells reflects the wider Kent pattern — ragstone and flint cottages, oast houses, Victorian terraces and coastal housing, and coastal weathering at Margate and Dover, lime work on ragstone.
The area sees drier than average inland, exposed on the coast, which is the single biggest factor in how long any render lasts here. Kentish ragstone is porous and traditionally lime-rendered, while the north kent coast takes some of the most persistent easterly exposure in the south east.
When basement tanking is the right call. Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.

FAQs
Basement Tanking in Tunbridge Wells
How long before I can paint new render?
Through-coloured systems need no painting at all. Sand and cement should cure for around 28 days before masonry paint goes anywhere near it.
Do you take a deposit?
For most domestic jobs we take a deposit to cover materials and scaffold, with the balance on completion. Terms are set out clearly in the written quote.
Can you match my existing render?
Usually, yes. We colour and texture match as closely as we can, though weathered render never matches a fresh batch exactly — we will be honest about how visible a patch will be.
Can any cellar be tanked?
Most can, but the right system depends on water pressure, structural condition and intended use. A survey establishes which approach is appropriate.
How long does basement tanking last?
A correctly designed and installed system carries a 20-year warranty. Type C systems need periodic pump servicing to maintain that.
