Basement Tanking in Carlisle
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Carlisle property owners come to us for basement tanking for one of two reasons: something has failed, or the house looks tired.
Cumbria is characterised by traditional slate and stone construction, lakeland cottages and exposed rural properties, with driving rain, saturation and moss growth on north-facing walls the recurring theme on the properties we survey.
The area sees the highest rainfall in England, which is the single biggest factor in how long any render lasts here. With the wettest conditions in england, breathability is not optional — sealing a cumbrian stone wall in cement causes damage within a few winters.
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 Carlisle
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.
