Seal Coating

Seal Coating can DOUBLE the life of your pavement by protecting it from its enemies: sun & oxidation, water, gasoline, and oil. Seal coating preserves the investment you have in your asphalt, while at the same time making your property safer, cleaner and more attractive. 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. Properly designed parking lots rarely wear out from traffic. Surface deterioration is usually caused by the weathering effects of the sun and rain, as well as the softening effects of gasoline and oil drippings.


Seal coating is the process of applying a liquid coal tar emulsion over existing pavement, in order to protect from moisture, ultraviolet oxidation and other environmental damages.  Seal coating also enhances the appearance of the asphalt by creating a darker, uniform color and appearance.  Slurry Seal is used as a preventative maintenance.  Because of its preserving and protective qualities, the lifetime of the pavement is drastically extended and leads to lower maintenance costs over the years.


Often times there are substantial cracks in the area to be seal coated.   In the most severe cases we will recommend that we crack fill before the seal coat.  Hot Rubberized Crack fill is the application of a heated rubber compound to asphalt cracks.  This fills the crack and seals it from further water penetration.  The cracks are cleared of all vegetation and debris beforehand.  Crack fill is used to repair large, singular cracks.  If left untreated, these cracks will lead to further damage, as water seeps in and enters the sub-base of the asphalt, eventually leading to "alligator" cracking, and then potholes.  Hot Rubber is used because it effectively seals the crack, while also being elastic, expanding and contracting with the weather and climate.


Striping is the “finishing touch” on a freshly paved, seal coated, saw-cut, or patched parking lot. Since striping is the most noticeable part of the parking lot, it is imperative the job is neat and efficiently laid out. Burtch Construction provides professional striping with attention to the smallest detail.
