ABOUT US

We read the base, then fix it right

Some damage is just on top, and some means the base underneath failed. Cracking that spreads like dried mud means the base gave out, and a new layer over it will crack again. Because we grade and pave, we know the difference and we tell you.

How asphalt repair works

We start by finding why it failed: a soft base, standing water, or age. We cut out and rebuild failed areas, rout and fill cracks, then sealcoat or overlay to lock water out. Crack seal as cracks show and sealcoat every two to three years to get the most life from the pavement.

Asphalt repair that fixes the cause

Our asphalt repair and maintenance covers pothole repair, crack filling, sealcoating and overlays across Sonoma County. We rebuild the base where it failed, fill and seal before water gets in, and resurface when the top is worn but the base is still sound.

Diagnose It Right

Asphalt problems and how we fix them

Some damage is just on the surface; some means the base underneath has failed. Because we grade and pave with one crew, we can tell the difference and recommend the fix that actually lasts, not just a patch that cracks again.
