Prevents Oxidation
Asphalt begins to dry out soon after it is placed. As pavement is exposed to oxygen, the asphalt binder (tar) hardens. This hardening results in a brittle surface that will eventually crack. The cracks enable oxygen and rainwater to penetrate the pavement, weakening it and reducing the pavement strength. Sealing the driveway decreases the pavement’s exposure to oxygen and water, therefore, extending pavement life. Your driveway lasts much longer and will look like new.

Resists ultraviolet rays
Ultraviolet rays from the sun can significantly contribute to pavement deterioration. UV rays will down the links between carbon bonds in asphalt causing it to change colour from a black to a light gray. Additionally UV rays will contributing to overall pavement deterioration and crumbling. Sealing the driveway will restore the rich dark colour of asphalt and prevent surface erosion from the weather.

Resists oil and gas spills
The driveway is where cars are commonly parked and maintained. Gasoline, oil and antifreeze will soften the asphalt making it weak and vulnerable to erosion. Sealing the driveway provides a protective layer that reduces the depth to which oil and gas can penetrate the pavement. This also results in easier maintenance and cleaning of the driveway
