Got a damp, smelly basement or cellar you can’t use? Our tanking service could be exactly what you need. It’s a permanent waterproofing solution that lines your walls and floors with protective membranes or slurry coatings—essentially creating a dry barrier that keeps water out for good.

Whether it’s groundwater seeping in from outside, or leaks coming from faulty plumbing, our team installs top-grade tanking systems that hold up for years. It’s one of our most in-demand services, especially in low-lying or older properties in places like Weston-super-Mare, Clevedon, and Portishead, where damp basements are common.

What makes our tanking stand out? It’s not just the products—it’s the precision. Everything is fitted by our experienced, in-house technicians. We make sure it’s done properly the first time to protect against future wet rot, dry rot, and long-term structural issues. You’ll end up with a clean, dry space ready to use however you like.
