Basement Tanking in Warwickshire
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Getting basement tanking right in Warwickshire depends far more on the substrate and the exposure than on the product name.
Warwickshire is characterised by timber framing, Victorian brick and extensive modern estate development, with conservation lime work around Stratford and render refresh on modern estates the recurring theme on the properties we survey. With a moderate inland climate, specification matters more in this part of the country than a national price list suggests.
Local factor. Stratford-upon-avon and warwick carry dense listed-building coverage where cement render is effectively ruled out.
Is basement tanking right for a Warwickshire property?
Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Basement Tanking in Warwickshire — questions
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.
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.
