swellable mastic for waterproofing and swellable tape installation

ARCAN swelling mastics are available as polyurethane swelling mastics and bentonite swelling mastics. A swelling mastic is used instead of simple adhesive for laying swelling tapes on rough surfaces. The swellable material evens out the unevenness of the substrate and prevents leaks. The swelling of a swelling mastic is comparable to that of a swellable water bar. This is why it is also known as swellable water bar from a cartridge. Swelling mastics are supplied in cartridges or tubular bags and are very easy to use, especially in hard-to-reach areas and pipe penetrations.
