Basement Tanking in Cheshire
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Cheshire property owners come to us for basement tanking for one of two reasons: something has failed, or the house looks tired.
Cheshire is characterised by black-and-white timber framing, Victorian brick and substantial modern housing across the commuter belt, with algae growth on shaded elevations and failed cement render on solid walls the recurring theme on the properties we survey. Local conditions bring a wet north-western climate, and that has a direct bearing on which systems are worth specifying.
Local factor. Timber-framed and heritage stock around chester needs lime, while the surrounding modern housing suits silicone systems.
Is basement tanking right for a Cheshire 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 Cheshire — questions
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.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
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.
