Basement Tanking in Cheltenham
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
If you are weighing up basement tanking in Cheltenham, the starting point is what your walls are actually built from.
Across Gloucestershire, Cotswold limestone, Regency terraces in Cheltenham and modern estate housing dominates, and lime render on Cotswold stone and conservation-compliant specifications is what we are called out to most often.
With moderate rainfall with wetter conditions on the Cotswold escarpment, specification matters more in this part of the country than a national price list suggests. Cotswold limestone is soft and porous, and a large proportion of the county sits within conservation areas where cement render is simply not permitted.
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 Cheltenham
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.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
