The Benefits Of Routing Prior To Crack Sealing

Water is the most destructive elements to asphalt and concrete parking lots. Crack sealing is performed as a preventative maintenance procedure to prevent the infiltration of water to the subgrade, thereby leading to pot holes and alligator cracks.

Although hot rubberized crack sealing is designed to prevent the destruction from water, not all hot rubberized crack sealing procedures are created equal.

For property / facility managers who are looking to get better longevity out of their crack sealing investment, there is an option called “crack routing”.

Benefits Of Crack Routing:

  • Crack routing utilizes a mechanical router to widen the crack to a predetermined width and depth (Typically 1/2″ X 1/2″). A 1,800 degree hot air lance is then used to further prepare the cracks by drawing out the asphaltic oils from inside the reservoir to create a thermodynamic bond with the new hot rubberized crack sealer.
  • By routing a working crack to a 1/2″ X 1/2″ width / depth, a clean reservoir is created to allow the hot rubberized crack sealer to bond properly to the walls of the crack During the winter months when the cracks are expanding, the reservoir has already taken the place of the expansion and will remain sealed
  • Crack routing allows the property / facility manager to obtain better value from the crack sealing application

Is Crack Routing The Correct Procedure For All Crack Sealing Applications?

No, crack routing is not intended for all crack sealing applications. Crack routing is not recommended for extremely wide cracks (Larger than 1″ X 1″) or for for cracks sealed prior with any hot / cold pour crack sealing product.
