Amersham, Buckinghamshire
Basement Tanking in Amersham
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Amersham and the surrounding Buckinghamshire area throughout the year.
Across Buckinghamshire, period cottages and chalk-built properties alongside Milton Keynes new-town housing dominates, and lime work on period stock and monocouche on newer estate housing is what we are called out to most often.
Amersham sits in a part of the UK that gets a moderate inland climate — worth factoring into any render decision. The split between conservation-area period property and modern new-build is unusually sharp here, and the two demand opposite specifications.
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 Amersham
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.
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.
