Sealcoating and crack filling

Crack filling, sealcoat and slurry coats that protect asphalt from sun, oxidation and water.

Ultraviolet rays, oxidation and pollutants break asphalt down over time. As the binder oxidizes, pavement turns gray and brittle, and in Southern California's sun that process is relentless.

There is no cure for oxidation, but there are ways to slow it and extend the life of your pavement. Sealcoat acts as a protective layer, much like the skin of an apple protects the fruit inside. Filling cracks first keeps water and the elements out of the layers beneath.

Sealcoat services

Crack filling
Filling cracks so water, sunlight and debris can't reach the inner layers of the pavement through the crack walls.
Sealcoating
A protective coating that slows oxidation and restores a uniform black surface.
Slurry coats I, II, III
Slurry seals containing fine aggregate that can also fill minor surface defects, in three gradations.
Restriping
Fresh stall lines and markings once the new coat is down.

What sealcoat can and can't do

Sealcoat is preventive. It protects pavement that is still structurally sound, and areas with high pollution, direct sun and low traffic benefit most. It does not add strength. Pavement that is failing from below needs repair first, through skin patching, remove-and-replace or an overlay.

Our estimators will tell you honestly which situation you're in.

Common questions

What does sealcoat actually do?

It forms a protective layer over the asphalt that slows oxidation from oxygen, UV and pollutants, the process that turns pavement gray and brittle. It also gives the surface a uniform finish.

Should cracks be filled before sealcoating?

Yes. Filling cracks keeps water and environmental elements from reaching the inner layers of the pavement through the crack walls. Sealcoat alone doesn't do that.

Will sealcoat fix potholes or alligator cracking?

No. Those are signs of structural or base problems. They need repair such as skin patching or remove-and-replace before any coating goes down.

What's the difference between sealcoat and a slurry coat?

A slurry seal contains fine aggregate as well as asphalt emulsion, so it can also fill minor surface defects and improve texture. See our slurry seal guide.
