Asphalt, Crack Sealing & Sealcoating Explained
Many people believe that a first impression is a lasting impression, that fairs true for any business. The look of your parking lot can affect a customer’s attitude before they even walk through your doors. Keeping your commercial driveway and parking lot well maintained can go a long way in promoting customer satisfaction and the overall impression of your business.
The crack sealing process:
In order to prevent costly repairs in the future, it is essetial to maintain your driveway properly. That can mean either crack sealing and/or sealcoating your driveway to prevent further damage, and of course to look nice! Who doesn’t love the look of a new sealcoated driveway?
CRACK SEALING & SEAL COATING, EXTEND THE LIFE OF YOUR ASPHALT
Crack sealing and sealcoating are essential for maintaining your asphalt driveway and extend its life. This in turn will save you the cost of repaving.
Sealcoating covers your entire driveway, it helps to extend the life of your asphalt driveway. Compared to the dollars per square foot that would be needed in order to repair or replace your damaged asphalt, seal coating is a reasonable expense in maintaining it. Sealcoating includes crack sealing.

Benefits of Sealcoating
If applied properly at the right time, sealcoating benefits the pavement in many ways:
Sealcoating will turn a gray brittle driveway into a driveway that appears to have been newly paved. It will fill small cracks leaving a smoother dark black surface.
Exposure to oxygen breaks down asphalt binders resulting in surface cracking. These cracks permit water to penetrate into the sub base, weakening it and reducing pavement strength. A weak foundation will cause considerable damage such as sinking, tilting, larger cracks and eventually potholes. Sealcoating will provide a protective layer from the natural elements.
A proper sealcoat will protect asphalt from gas and oils that dissolve asphalt. Asphalt and oil-based sealers are petroleum-based products that have little protection from similar chemicals. Therefore, it is important to apply water-based sealers such as asphalt emulsions, acrylics or coal tar to the surface. These products are impervious to gas and oil spills.
Ultraviolet rays from the sun break the links between carbon bonds within asphalt. As bonding agents deteriorate so does the quality and appearance of your driveway. This is another cause of asphalt errosion that can be prevented with a protective layer of sealer.
Another reason why sealcoating is so important in maintaining structurally sound pavements is because of the rapid freezing and thawing effects of winter. The freeze-thaw cycle wreaks havoc on asphalt surfaces. A cold climate enhances the danger of water being caught in the pavement and freezing. As the water freezes it expands causing individual pieces of aggregate to break apart. Sealcoating reduces these affects by making the pavement much more waterproof. The jet black color of the sealcoating raises the temperature of the pavement thus making water and ice evaporate quickly.
Sealcoating achieves a deep black color which absorbs sunlight resulting in heat. The warm surface helps to prevent water from pooling and maintains a more pliable asphalt surface. A flexible asphalt surface holds up better to heavy traffic during colder weather.
It is far less expensive to sealcoat your driveway periodically rather than replace your driveway. Sealcoating preserves asphalt for pennies per square foot.
