    Modular expansion joints have been widely used throughout the construction industry for well over 40 years. The primary design goal for this joint system is focused upon its long term ability to resist damage that results from sustained fatigues loads. Modular joints, although very complex in nature, must be water tight and be able to accommodate very large thermal movement without transmitting potentially damaging tensile or compressive forces to any given structure.

    LCL's Modular Joints are designed as multiple or single support bar joint systems depending on the required range of movement and the intended application. They are designed to accommodate structural movements through an arrangement of adjacent connecting seals that have a self regulating gap system designed to ensure that all seals open equally. The joints are made up of an arrangement of extruded edge and center beams that run perpendicular to the bridge's longitudinal axis and are interspersed with neoprene seals. The center beams in turn slide on support beams that are arranged to move along one or both edges. The support beams are designed to allow rotational and sliding movements.

    LCL's modular joints significantly reduce road surface traffic noise and vibration to a minimum and the design approach also results in a continuous water tight connection at both minimum and maximum opening apertures, very durable fatigue free connections and maintenance free components.
