Basement Tanking in Isle of Wight
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
We carry out basement tanking across Isle of Wight and the surrounding Isle of Wight area throughout the year.
Isle of Wight is characterised by Victorian seaside villas, stone cottages and coastal bungalows, with salt exposure and driving rain on an island with no sheltered aspect the recurring theme on the properties we survey. Local conditions bring exposed maritime conditions on all sides, and that has a direct bearing on which systems are worth specifying.
Local factor. Being an island, every elevation is a weather elevation — there is no consistently sheltered side, which changes how a whole-house specification is planned.
Is basement tanking right for a Isle of Wight 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 Isle of Wight — 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.
