Dura-Fill Mastics are hot applied patching compounds used to repair asphalt and concrete surfaces. They contain specially formulated, highly modified asphalt binders and select aggregates. Dura-Fill Mastics can be used as permanent repair solutions for wide pavement cracks, joint separations, alligatored pavement, utility cuts, potholes, spalls, manhole/drain surrounds and other applications. These products create durable bonds with the existing surface, are weight bearing and remain highly flexible. Mastics have superior longevity and can greatly reduce the costs of future repairs. Mastic technology is well established, and the value of these products is now putting them at the forefront of pavement repair programs. For more information about mastics please contact us directly.
