The Ground Crack Inducer is designed for inducing cracks from the bottom of the slab.
It is very easy to install and will ensure a positive break through the joint. Ground Crack Inducer is an inverted V-shaped durable PVC extrusion.
It is positioned on the subgrade before the dowel cradles are placed. It produces a weakening in the slab that initiates a crack in the slab from the bottom up.
