Joint Stabiliser

Summary

Joint Stabiliser - The Joint Stabiliser eliminates concrete joint load transfer problems with a spring-like mechanism which allows it to expand and contract with the slab.

Technical Information

The Joint Stabiliser is a split aluminium cylinder containing a screw and wedge torque mechanism. When inserted between two slabs and expanded the pressure provides the interlock needed to restore load transfer and virtually eliminates harmful slab movement.

The Joint Stabiliser is installed by coring a hole in the concrete slab at the joint location and replacing the core with the Joint Stabiliser which is then expanded to exert pressure to each side of the joint.

Typically the Joint Stabiliser units are spaced approximately 1 metre apart on the joint, with 4 units installed at each joint intersection 300mm from the intersection..

Joint load transfer capacity is re-established when the Joint Stabiliser is installed, resulting in smooth, uninterrupted passage for the Materials Handling Equipment (MHE) over the joint.
