Frequently Asked Questions:

 

Why seal coat?

A well sealed driveway protects the asphalt from oxidation and wear caused by exposure to the sun and prevents water from penetrating the surface of the pavement. Seal coat beautifies the pavement by providing a smooth black finish.

 

How long after our driveway is installed should it be sealed? 

At lower elevations, it's recommended to seal pavement 6 months to a year after it has been installed. However, the mountain climate requires us to wait a year.

 

How often should our driveway be sealed?
 

While most products require sealing every 2 years, our residential premium seal coat usually lasts a minimum of  3 years. Most driveways get four years of protection.

 

What causes asphalt pavement to fail?

 

The primary cause of failure is the penetration of water seeping into the asphalt subbase.

Oxidation leads to erosion of the top layer of fine particles and the appearance of larger stones and small cracks on the surface. If left untreated, these cracks grow over time and eventually allow water to penetrate to the base of the pavement. When water enters the base of the pavement, the subbase shifts and settles leading to further cracking and an "alligator appearance." When the pavement reaches this stage the only option is removal and replacement of the old asphalt
