SeismAtec — high-movement seismic joints
Systems, and where each one goes
Central-pan joints for gaps up to 500 mm, where the seismic separation between blocks governs the joint rather than the thermal range. The 450 is made here; the 400, 410, 420, 430 and 440 are supplied to order. Section drawings are illustrations, not shop drawings.
SeismAtec model range
Seismic systems for high-rise and critical structures — accommodating movement to 100% of the joint gap (ASTM E-1399 Class III), with gaps to 500 mm.

Gap ranges are taken from the current Vexcolt technical data sheets. Movement capacity is gap- and variant-dependent — always confirm against the TDS for your model, or send us your drawings.
Movement
The SeismAtec 440, animated through each direction it is rated to move. These are Vexcolt-group animations, not site footage; the movement each gap takes is in the data sheet.
