Basement Tanking in Keswick
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Keswick and the surrounding Cumbria area throughout the year.
The prevailing picture in Cumbria is traditional slate and stone construction, lakeland cottages and exposed rural properties. That means driving rain, saturation and moss growth on north-facing walls comes up more here than almost anywhere else.
Local conditions bring the highest rainfall in England, and that has a direct bearing on which systems are worth specifying. 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 Keswick
Does a tanked basement need a pump?
A Type C cavity drain system does — it relies on a sump and pump. A Type A barrier system does not, though a pump is sometimes added as a backup.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
