Seal Coating

Seal Coating- A Proven Process

What is Seal Coating?

Seal coating is the most economical method of street resurfacing. It is a commonly used process by municipalities across the nation.

Seal coating is comparable to other resurfacing methods in durability and effectiveness, but costs far less, (15-25% of the cost of pavement overlays).

Seal Coating is a economical surface treatment designed to protect and prolong the lives of pavements.

Why Seal Coat?

Asphalt roads are like the new paint on your house. The moment the application process ends the deterioration process starts. Much like paint, asphalt is subject to oxidation, sunlight, rain, freeze and thaw cycles. Pavement is also subject to a wide array of different traffic loads, use of equipment for snow removal and additional stresses by normal ground movement.

Seal Coating can be used on new pavements to increase traction, or to prolong the life of a pavement that is structurally sound but is beginning to age and may have some surface distress.

Benefits of Seal Coating:

  • Improve surface texture.
  • Waterproof the surface.
  • Protect the underlying pavement from oxidation, aging and traffic wear.
  • Give new life to dry, weather surfaces.
  • Seal small cracks and imperfections.
  • Economic way to resurface roads.

The Process:

The process begins with repairs to large cracks (see crack filling page) and a through sweeping of the street.

A uniform layer of a asphalt emulsion is sprayed by a distributor truck. This water based product seals small cracks and holds the rock chips in place.


Rock aggregate or chips are applied with a chip spreader. This machine actually pulls the truck, hauling the chips, behind it and lays down a programmable layer of chips.


The chips are immediately embed into the asphalt emulsion by the use of self-propelled rollers. The chips are left on the street until the asphalt emulsion has set and then the street is sweep to pick up any chips that did not become embedded.
