Seismic expansion joint covers engineered for multi-directional movement

Seismic joints need covers that do more than close a gap: they must accommodate multi-directional movement - opening, closing, shear and vertical displacement - and return to position without damage. The Genotek seismic and large-span range includes 33 systems engineered for thermal, seismic and settlement movement in floors, walls and ceilings.

Pan-and-cover designs accept the adjacent floor finish for a flush architectural appearance, while heavy-duty centre-plate systems suit exposed applications and trafficked decks. These covers are specified for hospitals, airports, stadiums and high-rise towers in seismic regions. Every system ships with installation details, and movement calculations are available on request. Send the movement figures from your structural engineer and we will select the correct system and blockout dimensions for each joint.
