Design, supply and construction of bridge expansion joint systems as a single package, from movement calculation to final commissioning.
A complete joint construction package begins with the movement calculation for the actual structure and temperature range, then selects the joint type, supplies the system and carries out installation and testing. Single-source delivery removes the interface risk between designer, supplier and contractor.
Movement capacity must cover thermal expansion and contraction, shrinkage, creep and live load rotation, each with the appropriate safety factor. Undersizing the joint is the leading cause of early failure, and is generally a design-stage rather than a construction-stage error.
