Basement Tanking in Chester-le-Street
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Chester-le-Street and the surrounding County Durham area throughout the year.
Most of what we see around Chester-le-Street reflects the wider County Durham pattern — stone terraces, former colliery housing and postwar estates, and frost damage to failed render and blown coats on exposed northern elevations.
The area sees cold winters with significant frost cycling, which is the single biggest factor in how long any render lasts here. Freeze-thaw is the dominant failure mechanism here, so water getting behind render does far more damage than it would further south.
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 Chester-le-Street
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.
