Cemcure Expansion Joints permits thermals contraction and expansion without inducing stresses into the elements. An Expansion joint is designed to absorb safely the expansion and contraction of several construction materials, absorb vibrations and permit soil movements due to earthquakes or ground settlement. Expansion joints are normally located between sections of bridges, paving slabs, railway tracks and piping systems. The Expansion joint are incorporated to endure the stresses. An Expansion joint is simply a disconnection between segments. In the concrete block construction, the expansion joints are expressed as control joints.
