SEAL COATING
Research has demonstrated that properly applied (and properly timed) seal coat can save the owner of a property literally hundreds of dollars over the life of a hot mix asphalt pavement parking lot. When automotive oil or gasoline leak onto an asphalt pavement, they will work to easily dissolve the similar chemicals in asphalt. Eventually all the asphalt binder is exhausted and the aggregates begin to unravel due to the absence of the binding cement.

This happens to all pavement including roads. The rate of pavement deterioration depends upon the traffic volume as well as climatic conditions. The next step is the development of minor cracks which widen and deepen with time. If the cracks are not repaired at this stage, water seeps into the base courses and damages the pavement's load bearing capacity. It is evidenced by rutting, shifting, and serious alligatoring. The pavement then must be either overlaid or completely removed and reinstalled, depending on the condition. The surface layer of pavement is under continuous attack from the weather and other destructive elements, eventually developing minor surface cracks. Again, aggregates start unraveling producing minor cracks which widen and deepen with time. The damage will continue if proper protective actions are not taken.

OUR PREPARATION & INSTALLATION METHOD

1. Clean pavement surface free of all debris, grass, and gravel with a vacuum street sweeper, tractor broom, blowers, shovels,and hand brooming. (cleaning method vary)
2. Clean oil spots and treat with oil spot primer.
3. Apply seal coat material uniformly at a rate of 0.14 - 0.17 gallons per square yard. Edges around curbs and sidewalks are applied by hand for accurate placement.
4. Barricade and allow final coat to cure a minimum of twenty four (24) hours under good drying conditions before allowing traffic.
