The two part PVC crack inducer and groove former induces a controlled crack in continuously laid concrete. Its hollow, braced section makes it strong enough to be vibrated direct into wet concrete. These are available in both top and bottom profiles.
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 polysulphide sealant is then applied.
The base Crack inducer is required in slabs exceeding 300mm in depth. It is placed directly below the line of the top crack inducer to form the stress relief joint
