Maintenance – Seal coating and crack filling
Because blacktop is naturally porous, water can seep into and through the paving. This not only causes deterioration, but results in ridges and upheaval due to frost and freezing. Asphalt is also softened and broken up by gasoline, lube, oil grease, certain wheel and tire cleaners, road salts and antifreeze which drip from cars. “Seal coating” protects asphalt with a coating that is impervious to these harmful elements. Unprotected driveways remain porous, dry out, become rough and lose their life rapidly, which you certainly want to avoid.
