Basement Tanking in Penrith
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Penrith and the surrounding Cumbria area throughout the year.
Across Cumbria, traditional slate and stone construction, lakeland cottages and exposed rural properties dominates, and driving rain, saturation and moss growth on north-facing walls is what we are called out to most often.
With the highest rainfall in England, specification matters more in this part of the country than a national price list suggests. 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 Penrith
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.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.
What areas do you cover?
We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
What is the difference between Type A and Type C waterproofing?
Type A is a bonded barrier that keeps water out entirely. Type C accepts ingress, then drains and pumps it away behind a membrane. Type C is more forgiving of structural imperfections.
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.
