Concrete parking lot building in Maricopa AZ - a lot built for cars and trucks

Most people who call about a lot are opening a business, adding parking beside a shop, or tired of patching worn asphalt and gravel. The price moves with the size of the lot, how thick the slab has to be for the traffic, how much digging and base work the ground needs, and whether old paving has to come out first. The schedule turns on permits, inspections and pouring around the heat. We take care of the permit paperwork and schedule the inspections when a job needs them, and the written estimate lays out the scope for your lot so you know what you're comparing.

We start by asking about trucks, because where heavy traffic runs changes how the lot gets laid out, and keeping trucks on their own route lets the car areas be built for cars, which usually makes for a more economical design. Then I measure and check grades, and we dig out to firm subgrade, the ground the slab sits on, and pack the base instead of raking dirt level, because that hidden layer is what keeps a lot from sinking with the soil. We set forms, add rebar, the steel that holds the slab together if it cracks, where the design calls for it, pour, and give it a broom finish, a light texture so tires and shoes grip. We cut control joints, grooves that give the concrete a planned place to crack, and plan those joints and the stall lines together so the finished lot looks orderly. Then the slab cures, kept from drying out too fast so it gains strength before traffic goes on it. If the budget gets tight, I'd rather spend it on the base than on the surface, because nobody sees the base on day one but everybody sees it when it fails.

A lot rarely stands alone. Light poles, signs and any wall or building at the edge need concrete footings under them, and we can pour those along with the lot. If the building beside the lot or an old slab you're tying into has settled, foundation raising brings it back up so the new concrete meets it at the right height.

Maricopa's city code says required parking, loading and driveway areas have to be paved with asphalt, concrete, paving stone or masonry, and accessible parking spaces have to be provided and kept up under the federal Americans with Disabilities Act and the Arizonans with Disabilities Act. Concrete meets the paving rule, and we lay out the accessible stalls with the rest of the plan instead of squeezing them in at the end. We take care of the permit paperwork and schedule the inspections when a job needs them, and if it isn't clear what yours needs, we ask the city or county building office before work starts.

Problem soils turn up all over Arizona, and collapsing soils shrink when they get wet or carry heavy weight like pavement, which is why we dig out to firm ground and pack the base instead of raking dirt level. The surest check for expansive soil is borings and testing from a geotechnical firm, and on a larger lot that's something I'd talk through with you before we price the base. We work the same kind of ground on jobs in Casa Grande and Chandler.
