Basement Tanking in Guildford

Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.

Our basement tanking work in Guildford starts with a free survey, because guessing at a render specification is how jobs go wrong.

Across Surrey, tile-hung and timber-framed cottages, Victorian villas and substantial modern housing dominates, and high-specification smooth render and appearance-led refurbishment is what we are called out to most often.

Local conditions bring a moderate southern climate, and that has a direct bearing on which systems are worth specifying. Work here skews heavily toward discretionary upgrade rather than failure repair, so finish quality and colour matching carry unusual weight.

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 Guildford

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.

Are you insured?

Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.

What areas do you cover?

We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.

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.
