Bentonite Rubber Waterstop Bar for Sealing Water in Concrete Joint
Bentonite's ability to swell enables it to fill small cracks and voids in concrete, preventing the ingress of water
around joints. And since clay is a natural material, bentonite is a popular waterstop choice for potable water applications.

Storage
As with other hydrophilic waterstop systems, bentonite must be kept dry prior to installation and concrete must
be poured immediately after the bentonite is applied. Exposure to rain or moisture can cause bentonite to
expand prematurely, damaging joints and weakening concrete as it cures. As with PVC waterstops, bentonite
can be displaced or damaged during subsequent concrete pours and extra care must be taken to ensure an
effective application. Storage temperature must be between 5 °Cand 30°C.
