Seismic Expansion Joints Type VKRH2-100

A seismic expansion flexible joint installed at the joints of facility structures.

Installed at joint sections of water facilities, this product prevents water ingress and leakage both inside and outside reservoirs and sedimentation basins, even when complex stresses and displacements—such as expansion, bending, torsion, and shear—occur due to earthquakes or differential settlement.

By adopting a self-sealing mechanism, the structure utilizes water pressure to enhance sealing performance, ensuring reliable sealing even if the rubber’s sealing force decreases over long-term use.
