Pavement Sealing Frequently Asked Questions
What is asphalt?
Asphalt is composed of mineral aggregates held together by petroleum-based asphalt cement, acting as the glue or binder... then compacted into place. A fine, cost effective product, but not maintenance-free.
Why does it need to be sealed?
Petroleum spills of fuel, oil and solvents attack the pavement and seep in deep beneath the surface, softening the aspalt and reducing adhesion. Sun and rain cause oxidization... creating raveling, cracks and even potholes.
Why aren't roads and highways sealed?
Unlike parking lots and driveways, highways are constanly re-compacted by continuous traffic. Further, highways are not subject to the continuous attack of petroleum derivatives in a specific spot or pattern.
What is asphailt Sealer made of?
GemSeal is made of a blend of high grade ball clays, water, refined coal tar and proprietory emulsifier milled into a coal tar emulsion to generate a paint like coating which insulates the petroleum-based asphalt from potential petroleum spillage and reduces the normal aging cycle of the asphalt.
Are all sealers alike?
No, GemSeal brand sealers were perfected from more than 30 years of manufacturing and testing experience, and especially formulated to contend with the particular paving problems of our local climates. GemSeal's proprietary processes, industry leading quality control program, and ongoing research and development assures GemSeal of its number one position in overall quality.
Is application expensive?
Depending on the current condition of your pavement, there may be a need to fill cracks, dig out soft spots damaged by petroeum spills, fill in potholes and generally patch the pavement. Then a recommended two coats of Gemseal could save you from costly repaving.
How long will it last?
Depending on weather and traffic conditions, sealcoating is recommended every two to five years. With periodic maintenance, your pavement life will last for years... without sealing, your pavement life may not exceed seven to twelve years.
How do I choose an applicator company?
Reputable contractors use quality workmanship, provide quality workmanship and are proud of their work. Ask them for a list of their satisfied customers so that you can check references.
