Basement Waterproofing

House owners often want to expand their homes. One option they have is to convert their cellar. To do so, they must install an effective basement waterproofing system. This step is crucial to stop leaks and keep the living area warm and dry.

Below-ground basement structures are prone to leaks. Seepage can cause massive problems. Therefore, it is vital that tanking is dealt with correctly. So, choosing a suitable basement waterproofing system for your needs is essential.

Type C Waterproofing provides drained protection for basements.

Install a cavity drain membrane system to keep water out of your living area. Use the membranes on the cellar walls and floors. The system creates a barrier with drainage behind it. Seeping water diverts into channels and flows to a drainage point. That point may need to be a pump-operated sump. If so, the pumps will discharge the water to an external drain. The cavity drain system provides reliable protection against flooding.
In addition to our membranes, drains and pumps, we stock various ancillaries. These include waterproofing tapes, fixing plugs and jetting eyes. We have everything you need for a successful job.

Type A Waterproofing provides barrier protection for basements.

Try using our tanking slurry to waterproof your basement. This method stops water from getting into your cellar under pressure. Prepare your walls first and put on two slurry coats to do it right. After the final coat has dried, add renovation plaster before the final finish. An effective tanking barrier prevents leaks.
Twistfix tanking slurry and floor junction fillet seal are cost-effective. We take pride in providing reliable systems that meet the needs of our customers. Our commitment to quality means our products are the first choice for those seeking waterproofing solutions.

Whether your project is a new build or a conversion, Twistfix stocks everything you need for basement waterproofing. Our membranes and tanking products are top-notch and have full BBA certification. Use them in line with BS 8102. Buy online at trade prices. We are sure you will be satisfied with the quality of Twistfix's products and its delivery service.
