Basement Tanking in Lancashire
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Getting basement tanking right in Lancashire depends far more on the substrate and the exposure than on the product name.
Lancashire is characterised by stone mill-town terraces, Victorian brick and exposed coastal housing at Blackpool, with driving rain on the Fylde coast and failed cement render on stone terraces the recurring theme on the properties we survey. Local conditions bring high rainfall and severe coastal wind exposure, and that has a direct bearing on which systems are worth specifying.
Local factor. Blackpool and morecambe sit fully exposed to irish sea weather, and render specifications that hold up inland regularly fail on the seafront.
Is basement tanking right for a Lancashire property?
Choose tanking for cellar and basement conversions, persistently wet below-ground rooms, and any space you intend to make habitable.
That decision gets made at the survey, not on the phone. We will tell you plainly if a different system would serve the building better — including when a cheaper one would.

FAQs
Basement Tanking in Lancashire — questions
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.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
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.
