Patch the old lot or pour a new one?
If the ground underneath is solid, upkeep can carry the lot. If it has sunk, it's time to pour new, and if the building beside it is settling, that's a foundation raising job.
Patching is enough when:
- Damage is in a few spots
- The ground still feels solid
- Water drains off after rain
- Cracks are narrow and not spreading
- You're restriping existing spaces
A new lot makes sense when:
- Cracks run across most of it
- Slabs have sunk or tipped
- Water pools in the same places
- The base has washed out
- Trucks now use it every day
- You're adding spaces or expanding

A reply from us
I come out and measure
I look at the site, measure and walk you through your choices, starting with approvals, the mix and truck traffic, because those set the layout and joints.
Your options explained
Written estimate and plan
You get a written estimate showing what's included and what isn't, like hauling old concrete, plus a plan with each step in order, including when you can park on it.
A written estimate
Approvals before trucks
We check with the offices covering your address before scheduling, and a new mix can take several weeks to approve, so that wait goes into the plan.
Approvals in hand
Pour, walkthrough and clean-up
Our crew forms, pours and finishes the lot and cleans up after. Then I walk the finished lot with you and go over how to care for it.

What concrete parking lot building includes
Layout and accessible spaces
Accessible spaces, van spaces included, go into the layout from the first drawing, so they aren't squeezed in at the end.
Digging to the subgrade
We dig out to the subgrade, the ground the slab rests on, and look for soft or swelling soil.
Fixing weak soil
Weak or swelling soil can be treated with cement, fly ash or lime, or swapped out for better fill.
An evenly packed base
We pack the base the same across the whole lot, because even support matters more over the years than how hard the ground is.
Forming, pouring and finishing
Our crew sets the forms, places the concrete and leaves a broom finish, a light texture that helps tires and shoes grip.
Joints and joint sealing
We cut joints on time and talk through sealing them, which the pavement trade group recommends unless local experience says otherwise.
Footings for poles and walls
Light pole bases or a low wall at the edge sit on concrete footings, which we pour within the same plan.
What drives the cost of a concrete lot?
Size is the start, but the ground decides a lot of it. How much soft soil we dig out, whether it needs treating or new fill, and how much base goes back in all add up. The base is the part you'll never see once it's poured, so it's the first thing people want to trim. I'd rather trim the finish, because a nice surface on a weak base just cracks sooner.
Traffic, drainage and approvals come next. Steady trucks mean heavier joint work, the city's stormwater rules can add features, and hauling out an old lot adds to it too. On timing, the approvals usually set your start date more than the pour does. Your written estimate puts a figure on your own site.
Why O'Fallon owners hire us for parking lots
I spent years building schedules for a busy company, then learned concrete on a crew and started this business in O'Fallon in 2017. I still lay every lot out in order before anything gets poured, because most failures I see start before the pour, with the base, the drainage or a rushed schedule.
I come out and do your estimate myself, and our crew handles the forming, pouring and finishing. I'll explain each step before you sign anything, so ask all the questions you want. When you're ready, call (636) 614-2331 or send the form.

Do I need a state permit to build a parking lot in Missouri?
You need a land disturbance permit from the Missouri Department of Natural Resources when the work disturbs one acre or more, or less if it's part of a larger plan that reaches an acre. That's why I ask for your site size in acres up front. Rules differ by city too, so we check with the offices covering your address, and when a permit is needed we handle the paperwork and line up the inspections.
How long does concrete mix approval take in O'Fallon MO?
A new mix design can take several weeks to approve. The city requires all concrete placed in O'Fallon to be approved by the Eastern Missouri Pavement Consortium, and approved mixes are posted online. I settle the mix at the first visit so that wait is planned for, not a surprise.
How many accessible parking spaces have to fit vans?
At least one of every six accessible spaces has to fit a van, according to the U.S. Access Board's ADA guide, counted lot by lot. Each lot or garage on the site needs its own accessible spaces, employee and restricted parking included. Adding spaces, resurfacing or resealing later brings the same rules along, while patching potholes or restriping a few spaces is normal upkeep unless it changes how usable the lot is.
Why does a concrete parking lot have joints?
Joints give the concrete planned places to crack, so cracks follow straight lines instead of wandering across the lot. Once pavement carries about 100 trucks a day, the cross joints get dowel bars, smooth steel bars that pass the load from one slab to the next. If you expect steady trucks, tell me early, because it changes how the joints are built.
How much does a concrete parking lot cost in O'Fallon MO?
I give you a figure after I've seen the site, because lot size, the ground under it, truck traffic and the approvals set the price. Your written estimate spells out what's included and what isn't. Call (636) 614-2331 to set up the visit.
How do I get a parking lot plan approved in O'Fallon MO?
Your plans go to O'Fallon's Engineering and Plan Review Group, which reviews and approves commercial and residential plans, while the city's planning staff handle zoning and land use questions. If the lot sits in the 100-year floodplain, that group's floodplain rules apply too. The city also requires stormwater practices that stay with the lot after it's built, and you send the city an inspection report on them every year.
