Top Crack Inducer is made in two parts from heavy duty PVC. The top section measures 25x10mm and is easily removed to form a groove in the concrete for subsequent sealing. It is inserted into wet concrete and will, with or without the aid of a bottom crack inducer, create a plane of weakness in a controlled position in the slab.

This Two Part crack inducer is designed to induce a controlled crack, therefore forming a stress relief joint in continuously poured concrete slabs.

When pushed into the finished level of wet concrete, the top section is then removed to form a void of approximately 25mm deep into which the 4254 polysulphide sealant is then applied.
