Sealcoating And Crack-Filling
WHAT IS SEALCOATING AND WHY IS IT NECESSARY?
Parking lots rarely wear out from traffic! Surface deterioration is usually caused by the weathering effects of the sun, rain, gasoline and oil drippings. Sealcoating can DOUBLE the life of your pavement by protecting it from its enemies like Sun, Oxidation, Weather, Water, Oil, & Gas.
Gray vs Black
Oxidation, the graying in color of asphalt pavement, is a sign of fatigue, aging and general surface deterioration. When unprotected pavement becomes oxidized, the aggregate will begin to ravel from the surface making the pavement rough. Once the surface becomes brittle, cracks develop, and the pavement deteriorates. Furthermore, water which accumulates in open pavement structures is a major cause of pavement damage.
Preventive maintenance before these damaging elements get a hold on your pavement is important. Sealcoating is the most cost effective maintenance procedure available and enhances the appearance of your pavement by giving it an attractive, easy-to-clean, black color finish.
Silica Sand is added to coal tar sealer to provide a heavier wearing surface which means that the sealer will last longer and will be more skid resistant then sealer which does not contain sand.
Sealcoating pavement for pennies a square foot can save dollars in future costly repairs or replacement!
What Is Tarconite?
Tarconite heavy duty sealer is a blend of emulsified high temperature coal tar and selected mineral fillers developed for use as a flexible, tough, longer-lasting protective coating for asphalt pavements. Tarconite is rubber fortified to provide up to 50% greater wear, flexibility, and adhesion than non-rubberized sealers.
When appearance and protection are foremost, Tarconite has been the line of defense to protect the longevity and beauty of millions of acres of asphalt pavement. Locking out spills and protecting against the elements, Tarconite delivers a rich, smooth, black finish that's unparalleled in the marketplace, year after year.

The two most important reasons you need to maintain and repair the cracks is because you don't want moisture to penetrate under the asphalt surface causing more damage to your driveway or parking lot. We recommend you sealcoat your surface as well, for added protection and preventative maintenance against the elements.
The second reason you should fill the cracks in your asphalt is because vegetation will begin growing in them. As the roots on vegetation get bigger, the plant root can actually push the pavement up and create even more damage. This breaks the pavement surface and other problems begin occurring.
Even worse, if water does penetrate the crack and seeps under the asphalt surface, this will almost always creates a soft spot which in turn can create a Pot Hole and if you live where the temperatures create ground freezing, then this moisture under the asphalt surface will freeze and push the pavement up. You might have seen this on other driveways or parking lots to know what we are talking about and now you know why it has happened.
All of these conditions can usually be avoided by practicing good maintenance and keeping these cracks filled as they occur, the best way to avoid Crack Filling is regular Seal Coating.
Crack cleaning and drying is done to provide a clean, dry work channel and to remove any loose materials from the crack, a clean, dry crack is extremely important, as a large percentage of sealant failure is caused by adhesion failure with the crack wall.
Crack cleaning can be done by hand tools, brushing or sweeping, air blasting, hot airblasting or sand blasting.
