Basement Tanking in Coleford
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
If you are weighing up basement tanking in Coleford, the starting point is what your walls are actually built from.
Most of what we see around Coleford 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.
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 Coleford
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.
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.
