Basement Tanking in Oswestry
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Oswestry property owners come to us for basement tanking for one of two reasons: something has failed, or the house looks tired.
Shropshire is characterised by timber framing, sandstone cottages and rural farm buildings, with lime render on timber-frame and sandstone in a conservation-heavy county the recurring theme on the properties we survey.
Local conditions bring moderate rainfall with exposed upland conditions in the south, and that has a direct bearing on which systems are worth specifying. Ludlow and shrewsbury hold large concentrations of listed timber-framed buildings where only lime specifications will get consent.
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 Oswestry
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.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
