Sealcoating is a fresh finish that increases the durability and aesthetic appearance of your asphalt for a fraction of the cost of new paving.
Proper sealcoating protects your asphalt from the extreme heat and harsh Arizona weather. It extends the life of the asphalt, improves the appearance of your property and reduces the cost of maintenance.
The primary reason to sealcoat asphalt pavement is to protect it from destructive natural elements. When pavement is exposed to sun, wind and water, the asphalt hardens or oxidizes.
A sealcoat combats this situation by providing a waterproof membrane which not only slows down the oxidation process, but also helps the pavement shed water which prevents it from entering the base material.
Sealcoating acts as a waterproofing agent minimizing the rate at which water enters pavement. It fills surface voids, which reduces exposure to oxygen and UV rays and lessens the depth to which oil or gas can penetrate the pavement. Without it, water can permeate more freely resulting in freeze/thaw expansion and contraction, and eventual structural failure.
Sealcoating leaves a smooth and even texture which makes the surface easier to maintain year-round. For example, sweeping is far more effective on a smooth surface. Sealcoating also adds a layer of protection against pressure washer damage, making it quicker and easier to maintain your pavement.
Asphalt is a petroleum product and therefore will always be affected by fluctuation in crude oil prices. Sealcoating preserves asphalt for pennies per square foot and can prolong the need for costly repaving.
