Simple pavement cracking becomes wide cracking (larger than one inch) when water channels and incompressible debris and vegetation enter the breach. Over time, thermal expansion/contraction, erosion, and ice and plant wedging, widens the once small crack and damages the road base. Wide cracking can also be the result of dry, brittle pavement materials.

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.
