Basement Tanking in Grimsby
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Grimsby and the surrounding Lincolnshire area throughout the year.
Across Lincolnshire, limestone villages, fenland brick and exposed coastal housing dominates, and wind-driven rain on the coast and movement on fenland substrates is what we are called out to most often.
With cold easterly exposure and low rainfall inland, specification matters more in this part of the country than a national price list suggests. The county splits sharply between exposed coastal strip and dry fenland interior, and the correct specification differs substantially between the two.
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 Grimsby
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.
How long does basement tanking last?
A correctly designed and installed system carries a 20-year warranty. Type C systems need periodic pump servicing to maintain that.
