Characteristics
Diajoint is an hydrophilic rubber joint made out 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.
Appearance: Kerb
Expansion in water after 14 days: > 425%
Swelling with prevented expansion: 1.43 N/mm2 // 207.4 lb/in2 (psi)
Elongation at break: 141 %
Maximum deflection: no tearing at an angle of 180°
Waterproofing sheets and hydro-expansive kerbs
for waterproofing foundation or onto the ground structures
Once in contact with the concrete casting, the joint expands its volume, sealing and waterproofing the casting from any infiltrations coming from the outside. It fills completely the small voids or gravel nests that are generally frequent at the bottom of vertical castings.
