Platte City was founded by Zadock 'Zed' Martin and incorporated as the Platte County seat in September 1843. Union forces razed the town during the Civil War on December 16, 1861, and outlaw history followed decades later — Jesse James reportedly planned (but never carried out) a bank robbery here in 1882, and Bonnie and Clyde shot their way out of a gunfight at the Red Crown Tourist Court just south of town on July 19, 1933. Platte City nearly tripled in population between 1960 and 1980 before growth slowed to a crawl in recent decades.
A County Seat With an Outlaw Past
Platte City was founded by Zadock 'Zed' Martin and incorporated as the Platte County seat in September 1843, according to Platte City's documented history. It's had more than its share of history since: Union forces burned the town on December 16, 1861 during the Civil War, Jesse James is said to have planned (but never pulled off) a bank robbery here in 1882, and Bonnie and Clyde shot their way out of a gunfight with police at the Red Crown Tourist Court just south of town on July 19, 1933. Platte City's growth has told its own story in the census: the town nearly tripled between 1960 and 1980, jumping 70.2% in the 1960s alone, but each decade since has grown more slowly than the last - only 2.0% between 2010 and 2020. That deceleration means Platte City is largely built out at this point, with a wide mix of concrete ages across town, from courthouse-era flatwork downtown to the newer construction from its fast-growth decades.
Why Concrete Sinks in Platte City
Platte County soil is a patchwork of river-bottom silt near the Missouri River and stiffer clay on the higher ground around town. Both move. The silt compacts and washes out when drainage is poor, leaving voids under slabs; the clay swells when soaked in spring and shrinks hard in summer and winter freezes. Add Missouri's freeze-thaw winters, and a driveway or walkway that was flat when it was poured can develop a dip or a trip-edge within a few years. Downspouts dumping water at the foundation, gutters that overflow, and grading that slopes toward the house are the most common culprits we see on service calls in Platte City. None of it means the concrete itself failed - it means the ground underneath it moved, which is exactly what concrete leveling is built to fix.
What We Level in Platte City
Most calls we get from Platte City homeowners involve a sunken driveway apron, a walkway that's pulled away from the porch, or a patio slab that rocks when you step on the corner. We also level garage floors, pool decks, porch and step slabs, and fill voids under slabs before they become a bigger problem. Our process is the same no matter which slab is misbehaving: drill a few dime-sized holes, inject expanding polyurethane foam underneath, and watch the slab rise back to level in real time. The foam is lightweight, so it won't add stress to soil that's already struggling to support the concrete, and it's waterproof, so it won't break down if it gets wet again next spring. It's the same driveway leveling and patio leveling approach we use across the Kansas City metro.
Polyjacking vs. Mudjacking for Platte City Homeowners
Mudjacking has been the traditional fix for sunken concrete for decades, and it does work by pumping a heavy cement-based slurry under the slab through large holes. The problem is the slurry's own weight - on ground that's already too soft or too clay-heavy to hold the slab up, mudjacking material can compress or wash out again as the same freeze-thaw and wet-dry cycles keep working on it. Polyjacking uses expanding polyurethane foam instead. It's a fraction of the weight, cures in minutes rather than days, and goes in through holes closer to the size of a coin. For Platte City properties near the river bottoms or on clay-heavy lots, that lighter footprint matters. If foam isn't the right fix for your situation, we'll tell you straight - that's part of giving an honest, free estimate.

Frequently asked
How much does concrete leveling cost in Platte City?
It depends on the size of the slab and how much foam it takes to lift it, so we don't quote prices sight unseen. We'll come to your Platte City property, look at the settlement, and give you a free, no-obligation estimate on the spot.
How long does concrete leveling take?
Most residential jobs are finished in a matter of hours, not days. The foam cures in minutes, so you can typically walk on the repaired area in about 15 to 30 minutes and drive on it within 1 to 2 hours.
Is polyjacking a permanent fix?
Foam won't break down or wash away like loose fill can, and it won't overload soil that's already soft. That said, if the underlying drainage problem that caused the settling isn't addressed, any concrete leveling method can eventually need a repeat visit - we'll point out drainage issues we see during the estimate.
Will the repair match the rest of my driveway or patio?
We're lifting and leveling your existing concrete, not pouring a new slab, so the color and texture stay exactly what you already have. The small injection holes are patched flush with the surface.
Do you serve areas outside Platte City?
Yes - we regularly work throughout this part of the metro, including Weston, Leavenworth, Lansing, Smithville, Parkville, and Gladstone, along with the rest of the Kansas City metro on both sides of the state line.
Is it true Bonnie and Clyde had a shootout near Platte City?
Yes. On July 19, 1933, Bonnie and Clyde were involved in a gunfight at the Red Crown Tourist Court just south of Platte City. The town was also founded in 1843 and briefly targeted by Jesse James, who is said to have planned a bank robbery there in 1882 that never happened.
