Asphalt Repair & Patching in Antioch, CA

Asphalt repair and patching covers everything short of repaving: filling cracks, fixing potholes, and cutting out and rebuilding areas that have failed. The key is to find out why the pavement broke. In Antioch the usual reasons are clay subgrade that has softened after the winter rains, water entering through cracks that were never sealed, and heavy vehicles on pavement that was built thin. A patch over those problems lasts a season; a repair that fixes them lasts much longer.

Types of repair

• Crack sealing: cleaning cracks out and filling them with hot rubberized sealant to keep water out of the base.
• Cold patch: a temporary fix for small potholes, useful in wet weather until a permanent repair can be made.
• Hot patch: hot mix placed in a prepared hole and compacted.
• Saw-cut, full-depth patch: the damaged area is cut square, removed down through the base, rebuilt and paved. The most durable fix for alligator cracking and soft spots.
• Infrared repair: the existing asphalt is heated, reworked with new material and compacted, leaving no seams. Best for smaller surface defects.

Reading the damage

Alligator cracking, where cracks connect into small blocks, usually means the base has failed under load. Long cracks along the edge often mean the edge is unsupported. A depression that holds water points to soft subgrade. Cracks that run in straight lines may be reflecting joints from an old concrete slab below. Each one calls for a different repair, and we explain what we see before quoting.

Before the rains

The best time to seal cracks and patch potholes in Antioch is late summer and early fall, before the November-to-March rains. Water that gets through an open crack into a clay subgrade softens it, and the next heavy vehicle pushes the pavement down. Sealing in the dry season keeps that from starting.

Lots and HOAs

For parking lots and private streets, we can map repairs across the property and price them as a package, often combined with sealcoat and restriping. Patching the worst areas first and sealing the rest can put off a full repave for years.

Utility cuts and trenches

Trenches left by plumbing, irrigation or electrical work often settle and crack. We cut back to firm pavement, compact the backfill and patch to match the surrounding surface. Work in the public right-of-way, such as a cut across a sidewalk or gutter, falls under the City of Antioch encroachment permit.
