    Expansion joints are integrated with bridge decks in order to accommodate the relative movement between the structure's segments, as well as the movement between the superstructure itself and support abutments. Such movement is the result of thermal expansion and contraction, creep and shrinkage of the concrete, substructure settlement, live dynamic loads and other causes.

    As a result of further advanced research and development, LCL's single cell joints are manufactured using extruded steel rails that ensure a watertight interlocking mechanism by using a neoprene seal. What makes LCL's Single Cell Expansion Joint so unique is the additional protection it provides to underlying structures, such as abutments. This is achieved through the incorporation of a collector reservoir which runs along the bottom of the steel rail joint and which collects and drains away water, de-icing chemicals in cold climates and debris. This unique feature further adds protection against corrosion and extends the useful life of the concrete and steel in structures.

    Furthermore, the thickness of the rail is optimized to increase the joint's resistance to fatigue, therefore ensuring that the joint has significantly increased durability throughout its service life. The interlocking design of the extruded rails enables easy installation of the neoprene seal during production and in the field.

    LCL's strip seal expansion joints have been extensively tested by independent organizations to ensure their water tightness and resistance to fatigue. LCL has also thoroughly, and independently, tested the movement capacity of its joints for skewed, curved and straight bridge decks.

    All of LCL's expansion joints have been extensively tested by independent organizations to ensure their water tightness.
