Unsealed or improperly sealed pavement joints can undergo deterioration of their corners and walls, which is common when a flexible pavement and rigid pavement meet. This type of pavement distress allows greater channeling and pooling of water and infiltration of incompressible materials, widening the joint and causing material to break loose.

For cracks greater than one inch and pavement damage of depths up to two inches, GAP Mastic is a more durable and substantial repair solution than traditional crack sealants. Economical and versatile, GAP Mastic can be applied to wide cracks, cupping, depressions, fatigue cracking (alligatored areas), small voids and potholes, and open seams.
