Basement Tanking in Cirencester
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Our basement tanking work in Cirencester starts with a free survey, because guessing at a render specification is how jobs go wrong.
Most of what we see around Cirencester reflects the wider Gloucestershire pattern — Cotswold limestone, Regency terraces in Cheltenham and modern estate housing, and lime render on Cotswold stone and conservation-compliant specifications.
Cirencester sits in a part of the UK that gets moderate rainfall with wetter conditions on the Cotswold escarpment — worth factoring into any render decision. 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 Cirencester
Does a tanked basement need a pump?
A Type C cavity drain system does — it relies on a sump and pump. A Type A barrier system does not, though a pump is sometimes added as a backup.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
