foundation sealing / bentonite
Hydrophilic bentonite joint for the sealing and waterproofing of concrete casting joints of concrete structures.
Diajoint is an hydrophilic rubber joint made of bentonite polymer, to be used as water stopper for concrete casting joints of concrete structures. The joint is composed by 75% of sodic bentonite and 25% of organic binder.
Once in contact with concrete casting, the joint increases its volume sealing and waterproofing perfectly the surface from any eventual infiltration coming from outside and filling holes generally present on concrete vertical casting.
