HYDRO SELFEXPANDED JOINT FOR CONCRETE CASTING JOINTS
DIAJOINT is a self hydrophilic joint made of 75% of sodic bentonite and 25% of organic binder. Once in contact with concrete casting, the joints expands, sealing and waterproofing the concrete casting from eventual outside infiltration. Diajoint has a delayed initial expansion even if in direct contact with the water. It does not require a fixing net, it has high resistance, even after the expansion due to water absorption.
