Crack sealing done right!

​

Crack sealing is one of the most crucial steps in maximizing the longevity of asphalt parking lots.  The primary objective is to minimize moisture intrusion which can rapidly deteriorate sub-surface conditions, leading to more cracking and eventually the dreaded pothole.

​

25 plus years of experience has taught PMI that simply applying sealant does not result in a lasting repair.  Routing the cracks before they are sealed is essential

​

• Routing ensures enough sealant can be applied to the repair – penetrating the crack and not simply sitting on the surface

• Ensuring adequate rubber sealant allows for expansion and contraction throughout the seasons.  If the rubber can’t sufficiently expand, rubber will detach from the asphalt

• Additionally, the routed channel provides a sidewall surface that allows for optimum adhesion of the sealant, dramatically reducing the risk of the seal becoming unseated and rendered useless
