Crack routing involves the utilization of a mechanical routing machine to expand a crack to a specified width and depth. This method effectively widens the crack, creating a smooth surface that allows hot-rubberized crack sealer to firmly adhere to the crack walls.

Routing cracks before applying hot-rubberized crack sealer significantly extends the lifespan of the repair compared to standard "blow & seal" methods. This process often doubles the longevity of crack sealing applications. Consequently, property and facility managers can achieve greater value from their overall crack sealing efforts.

By creating a wider reservoir through routing, the sealant gains greater volume, allowing it to effectively expand and contract while safeguarding its integrity. This results in a more durable and long-lasting crack repair.
