Basement Tanking in Fort William
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Fort William property owners come to us for basement tanking for one of two reasons: something has failed, or the house looks tired.
Most of what we see around Fort William reflects the wider Inverness-shire pattern — stone cottages, croft houses and highland rural properties, and frost damage and driving rain on remote highland properties.
Fort William sits in a part of the UK that gets severe highland conditions with heavy rain and hard frost — worth factoring into any render decision. Altitude, remoteness and severe frost cycling combine here to make breathable lime harling the only durable specification on traditional stock.
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 Fort William
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.
