Basement Waterproofing in London

Need help with your basement waterproofing? Call us: 0208 936 7745

ProTen provide expert below ground basement waterproofing solutions throughout London.

As basement waterproofing contractors, we carry out damp and basement surveys and we install the waterproofing systems that will turn uninhabitable basements into dry, clean living spaces or resolve any basement damp-related problems to keep your basement or cellar free from water damage.

We draw upon decades of industry experience to plan and deliver a suitable basement waterproofing solution for your project. We use a range of protection methods, including cavity drainage membrane, drainage channels, tanking, sumps and pumps and damp proofing systems – but the path we choose will depend entirely on your site’s requirements.

Whether you’re a homeowner based in the heart of the capital, or a commercial business operating within Greater London, ProTen are here to help.
