Basement Tanking in Altrincham
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Getting basement tanking right in Altrincham depends far more on the substrate and the exposure than on the product name.
Most of what we see around Altrincham reflects the wider Greater Manchester pattern — dense Victorian terraces, mill-town housing and large postwar estates, and persistent algae growth and damp in solid-wall terraced housing.
Altrincham sits in a part of the UK that gets high rainfall and frequently overcast conditions — worth factoring into any render decision. The combination of high rainfall and dense terracing means shaded rear elevations here green up faster than almost anywhere else in england.
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 Altrincham
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.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
