Basement Tanking in Dereham
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Dereham and the surrounding Norfolk area throughout the year.
The prevailing picture in Norfolk is flint and brick cottages, Norfolk carrstone, thatch and coastal housing. That means lime render on flint and clunch, coastal exposure on the north Norfolk coast comes up more here than almost anywhere else.
The area sees the driest county in England with cold easterly coastal exposure, which is the single biggest factor in how long any render lasts here. Flint walls need lime because the mortar does the work, not the stone — cement on flint causes the face to spall off in freezing weather.
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 Dereham
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.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
