Movement Joint Systems from Unison Joints

Designer Range movement joints system from Unison Joints

Polished concrete, bulky-goods EJ system: Projects by Unison Joints

Movement joints are constructed to provide relief from ductile stress that is caused by changes in ambient temperature. Concrete shrinks and expands along with changes in moisture, temperature, and seismic movement. If necessary measures aren't taken to address the contraction and expansion of concrete, unsightly irregular cracks will appear.

Expansion or movement joints are designed to segment slabs, walls and columns in structures to enable thermal, shrinkage, seismic, wind and other movement to occur. Structural movement gaps are created in concrete slabs, columns and walls by forming, tooling, sawing, and placing of joint formers.

Vertical and horizontal movements between adjoining parts of the structure are accommodated by movement joint systems. This mechanism minimises the appearance of cracks on the surface of a concrete. The movement joint system must be carefully designed, located, and installed properly.

The movement joints from Unison Joints are designed according to their six-way movement principle, which permits a multi-directional, six-way movement pattern that minimises the risk of damage to the surrounding substrate, prevents deformation of cover plates, and shearing of screws that holds the expansion joint system firmly in its place.
