What is internal waterproofing?

Internal waterproofing, otherwise known as tanking, involves installing a waterproof membrane to the internal walls and floor of your basement. This waterproof membrane is covered in studs and cavities which effectively gather and channel moisture, allowing it to drain harmlessly away through the pump drainage system.

We use only the highest quality and effective internal waterproofing products on the market and with a 10 year guarantee on our cavity drain membranes, you can rely on us to keep your basement protected from damp for years to come. Get in touch today on 01202 737739.

Why is internal waterproofing important?

Simply put, without effective internal waterproofing in place, your basement or cellar will be rendered unusable. If you are planning a basement conversion or have a new build underway, then internal waterproofing is something you need to consider if you want to make your basement into a habitable space.

Even if you are only planning to use your basement for storage, your items will be totally unprotected from damp and are likely to gather mould and become damaged, not to mention smell terrible without a waterproof membrane in place.

Internal waterproofing is an important step in making both new and old basements protected against damp. Due to their underground location, basements and cellars are particularly vulnerable to developing damp problems, so internal waterproofing is a must if you plan to make use of this space.
