Ground Crack Inducer is an inverted V-shaped durable PVC extrusion, 3 m long and available in 25 mm and 50 mm heights. It is positioned on the sub-grade before the dowel cradles are placed. It produces a weakening in the slab that initiates a crack in the slab from the bottom up.

Ground Crack Inducer should only be used when Crack-A-Joint™ is used, or when saw cuts are to be made in the slab on the same day as the slab is poured.

    • Supplied in standard 3 m lengths off the shelf
    • Available in 25 mm and 50 mm heights
