Basement Tanking in Ely
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Ely property owners come to us for basement tanking for one of two reasons: something has failed, or the house looks tired.
Most of what we see around Ely reflects the wider Cambridgeshire pattern — historic centres, extensive fenland brick and large modern developments around Cambridge and Peterborough, and substrate movement on fenland ground rather than weather-driven render failure.
The area sees the driest region in the UK, which is the single biggest factor in how long any render lasts here. Low rainfall means less algae and slower weathering, but peat and fen subsoils cause more movement cracking than anywhere else in england.
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 Ely
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.
