Concrete parking lot building in Monrovia CA - pavement built for your traffic

Maybe you're adding parking behind a shop, or an old lot is cracked, sinking and holding water after every rain. The price moves with the size of the lot, how much old pavement we tear out and haul off, and how heavy the traffic is, because trucks call for thicker concrete and more joint work than cars do. The schedule turns on your engineer's design, the city's permit steps, the weather and the curing time before anyone parks on it. If only a few broken sections need to come out, concrete cutting can take them out cleanly, and when I come out I measure it all and write down what's included, like removal and hauling, so you can see what your price covers.

We start by asking how many cars and what kind of trucks the lot will see, because that shapes how the slab and joints get built, and we get your engineer's numbers in hand before we price it. Then we tear out what's there, dig down and pack the subgrade, the ground the slab sits on, because a base that's only raked level settles with the dirt and takes the concrete with it. We set forms and screeds, the guides we level the concrete against, so the surface falls the way the drainage plan says and water runs off instead of pooling. We pour early in the day when we can, since concrete that dries too fast in the heat ends up with a weak, dusty top, and we give it a broom finish, a light texture that gives tires and shoes some grip. Control joints, shallow cuts that give the slab a planned place to crack, go in on time rather than whenever, and the slab cures, sitting undisturbed while it gains strength, before anyone parks on it. If the budget's tight, I'll trim the finish before I touch the base, because nobody can fix a base once it's under concrete.

Most lots come with other concrete work around them. Light poles, a sign or a low wall along the edge each stand on concrete footings, and it's simpler to pour those as part of the same job. If the building beside the lot has settled, foundation raising is worth looking at first, because new pavement poured tight against a sinking wall ends up cracked along that edge.

Before paving here, the city says to check with its Planning Division on zoning, and then Building and Safety staff meet with you to decide whether your plans need a city review. Grading permit applications go to the city's Engineering Department, and if any part of the grading falls between October 15 and April 15, a separate erosion and sedimentation control permit may be required, which is worth weighing when you pick a start date. Any work in the street itself, like a new driveway or curb, needs a city construction permit. We haven't found a city rule that spells out which private lots need a building or grading permit, so we check with the office that covers your address before we set a date, and if the job needs a permit we sort out who pulls it and have it in hand before work starts.

We're based in Monrovia and work across the San Gabriel Valley. The lots we're asked about usually sit behind a shop, an office or an apartment building, often with old pavement to tear out and a building wall that water has to run away from, and we plan them the same way on jobs in Arcadia and Duarte, starting with the traffic and the water.
