Joint Free Slabs

JFS System

The joint free slabs crack inducer grid consists of plastic tubes and four way junctions that are assembled on site and installed on the ground, their primary purpose being to induce a closely spaced network of fine cracks throughout the entire length and breadth of the slab. With this system vast areas of slab on grade can be constructed much faster than is possible using traditional details, and there is the potential for sizeable direct savings in both the construction cost and the construction time.
