Expansion devices are components of bridge equipment that are particularly susceptible to damage. Exposure to aggressive environmental factors, overloading, inadequate maintenance and conservation practices, as well as the selection of unsuitable devices during the design stage often contribute to the accelerated wear of expansion devices. At the same time, improper operation and loss of tightness of expansion devices often lead to accelerated degradation of the end sections of spans, bridge abutments, and their components such as bearings or prestressed tendons anchorages. BBR Polska, as a specialized entity involved in the design, production, and installation of expansion devices, as well as repair technologies, can offer comprehensive services for repairing or replacing damaged or worn-out expansion devices.
