Asphalt pavements are subject to deterioration, due
to water and sunlight. Water intrusion is the leading cause of pavement failures. Water softens the base and sub-base under
the asphalt. This situation leads to cracks or "alligator" areas and those areas eventually become potholes. Ultraviolet rays
from the sun are the second leading cause of pavement failures. Sunlight oxidizes the pavement causing the asphalt to become
brittle and to begin to unravel. Unprotected, those pavements will eventually fall apart.
The primary method of protecting valuable investments
in asphalt surfaces are sealcoating and cracksealing. The first line of defense against water intrusion is cracksealing. Cracks
in asphalt pavements begin at the bottom of the asphalt and work their way to the surface. Once a crack reaches the surface,
the volume of water reaching the base increases dramatically. If left alone, the crack will continue to widen and the pavement
will eventually fail. Properly sealing those cracks will greatly reduce the flow of water.
Sealcoating asphalt is very similar to painting
wood. A sealcoat provides a protective barrier between the pavement and water and sunlight, while providing a new, eye-pleasing
look to the property. The keys to quality sealcoating and cracksealing are preparation and using superior products in the
application. We believe that no other contractor on the North Olympic Peninsula spends the preparation time that Rainbow Sweepers
does for both sealcoating and cracksealing. We also use only top-of-the-line products, thus assuring the best possible results
on each and every job.
You can also expect our crews to work in a professional
and courteous manner and, through careful planning and efficient operations, we can minimize the disruption to your business.
Frequently, when we are called on to provide estimates or long-term pavement
maintenance recommendations, certain areas of the asphalt are alligator-like, or there may be potholes
present. Neither sealcoating nor cracksealing will fix these problems. Depending on the cause and severity of the problem,
sawcutting and/or removing and replacing with “hot-mix” asphalt will be needed. If the job is too large for us
to tackle, we work hand-in-hand with Lakeside Industries to get the work completed in a timely manner.
