Basement Tanking in Newcastle
Cementitious tanking and cavity drain systems for basements, cellars and below-ground rooms.
Getting basement tanking right in Newcastle depends far more on the substrate and the exposure than on the product name.
Most of what we see around Newcastle reflects the wider Down pattern — stone and brick cottages, coastal villas and modern housing, and coastal salt and driving rain on exposed peninsula properties.
The area sees wet with strong coastal exposure on the Ards peninsula, which is the single biggest factor in how long any render lasts here. The ards peninsula is exposed on both sides, so properties there weather from multiple aspects rather than one prevailing direction.
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 Newcastle
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.
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.
