Bentonite Waterproofing

Cetco Swelltite is a waterproofing bentonite sheet membrane composite consisting of a thick layer of sodium bentonite compound integrally bonded between a tough geomembrane liner and a clear poly siliconised release liner.

This product is an excellent example of ‘bentonite waterproofing’. What is bentonite waterproofing? Bentonite is a clay substance which coheres, binds, seals and thickens – you can see straight away why it would be useful in building and construction, right? As a waterproofing membrane, it hydrates with moisture – the kind that is found in soil naturally – and creates an impregnable waterproof barrier. It also contracts and expands infinitely, so that it won’t crack and warp in the process, meaning it will be good for the life of the project.

It is therefore great for heavy duty below ground jobs, such as back-filled concrete walls, masonry block walls, earth-covered roofs, and tunnels. If you’re looking to complete a job that uses bentonite waterproofing, call us today for a consult.
