Concrete Slab Services in Lodi, California

Residential slabs price per square foot installed, covering excavation, base prep, rebar, and finish, and the rate moves with access and soil. A garage slab prices off square footage, base prep, and the thickness the use calls for. A patio slab depends on size, finish, and how much grading the yard needs first. Thicker slabs with heavier rebar for shop floors or vehicle loads are at the higher end. We provide an itemized per-square-foot quote after measuring the site.

Residential foot traffic (patio, walkway): 4 inches. Vehicle traffic (driveway, garage): 4-5 inches. Shop floor with heavy equipment or lifts: 5-6 inches. ADU or addition foundations require engineering specifications. We size the slab to the expected load.

A patio slab on grade typically does not require a permit in Lodi. Driveways may require a permit depending on proximity to the street and approach modification. Structural slabs for foundations, additions, and ADUs require a permit and inspection. ADC handles the permitting process when required.

Concrete reaches 70% of its strength within 7 days and full design strength at 28 days. For residential slabs, light foot traffic is typically safe after 24-48 hours. Vehicle traffic: 7 days minimum. Heavy equipment: 28 days. We provide cure time guidance specific to your slab use.

Most residential slab cracking is caused by inadequate base prep (uncompacted or poorly graded subgrade), soil movement under the slab (common with expansive clay in the Central Valley), missing or incorrectly placed control joints, and shrinkage during curing. Proper base prep and control joint placement are the two biggest factors within the contractor’s control.

Yes, with the right approach. Hot weather accelerates hydration and can cause cracking if the slab dries too fast. We schedule pours in the early morning, use a retarder in the mix when temperatures exceed 90 degrees, and cure with wet burlap or curing compound to manage the hydration rate. Summer pours done right are just as durable as winter pours.

You can walk on it the next day. Vehicles and heavy loads wait 7 days minimum, and full design strength comes at 28 days. In Central Valley summer we pour early and keep the slab wet through the first few days, because concrete that cures too fast in 100-degree heat ends up weaker and more prone to shrinkage cracking than concrete that took its time.

Some cracking is normal as concrete shrinks during cure, which is why control joints get cut in the first place. Those give the slab a planned place to crack. What is not normal is a crack that keeps widening, one where the two sides sit at different heights, or one that runs through a joint instead of along it. Those point at base failure or soil movement underneath, and around Lodi and Stockton that usually means expansive clay that was never properly prepped.
