Why Seal Coat?
When harsh winters and constant weather changes begin to take their toll on asphalt driveways, your property’s appearance suffers. Worse yet, it shortens the service life of your driveway.
Why Asphalt Pavement Fails
The number one reason why asphalt driveways start to fail is the penetration of water into the asphalt base. This happens when the driveway pavement surface oxidizes, causing the asphalt to dry and become brittle. Erosion of the top layer of fine particles follows, revealing larger stones and small cracks.
If left untreated, the driveway cracks will grow over time, eventually allowing water to penetrate to the base of the pavement. Water entering this base material settles and leads to further driveway cracking and an “alligator appearance.” Once pavement reaches this stage, removal and replacement is your only option.
Sealcoating: Your Best Protection
Sealcoating seals the asphalt pavement, which prevents oxidation and top layer erosion. Driveway sealers replace the fine particles that have been lost on older asphalt driveways. The process also seals small fissures before they turn into large driveway cracks, and prevents water from seeping to the base material.
In addition, driveway sealers protect asphalt from the harmful effects of the sun and chemical spills such as oil and gasoline. The attractive black surface provided by driveway sealcoating is easily cleaned, and ideal for painting parking lot lines and other markers. Finally, sealcoating costs pennies a square foot compared to the dollars needed to repair or replace damaged asphalt driveways.
