Infrared Patching

Infrared Patching

Infrared technology heats the surface, softening the asphalt without burning. The use of infrared patching is a less disruptive and a more cost effective repair for cracked areas and potholes.


Sunlight (oxidation), rain, and freeze/thaw cycles along with vehicle traffic all contribute to the depletion of asphalt oils, which causes asphalt to shrink, become brittle, and ultimately crack.


RePLAY is a patented solution that extends the life of new and existing asphalt surfaces and is proven to reverse the oxidation process and maintain the skid resistance of your paved surface.


The correct and consistent application of coal tar sealer on the surface will prevent further damage, dramatically increasing the life and curb appeal of your asphalt.
Catch Basin Repairs

Catch Basin Repairs

Catch basins are installed in parking lots to provide adequate and correct drainage of water off of the surface. Catch basins are often the first areas of a parking lot to fail.
Tennis Courts

Tennis Courts

The best constructed tennis courts, basketball courts and running tracks will offer many years of serviceable use, but must be properly maintained with a regular maintenance plan.
GAP Mastic

GAP Mastic
