Ground Crack Inducer from Danley Construction

Danley Construction Products provide Ground Crack Inducer, which is an inverted V-shaped durable PVC extrusion, 3m 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.
