Structural Expansion Joint Systems

How do I select an expansion joint cover for movement range and traffic loads?

An expansion joint accommodates specified building movement; seismic selection depends on the required seismic design displacement. Gap width alone is insufficient: compare opening, closing, vertical movement, loads and installation depth. Match the system to the project engineer’s calculations.

Before requesting a quotation

Prepare the product code, dimensions, quantities, application, substrate and technical requirements. Confirm suitability for the project before ordering.

Can a surface-mounted expansion joint cover be used in a renovation?

Start with a measured survey of the existing opening, floor levels and supporting edges. Then compare the required movement envelope with the selected product record. Surface mounting can change the edge transition and clearance at doors; it is not simply a cover-width choice. Send the joint location, survey dimensions, traffic description and installation constraints with the BULDX model under review.
