Concrete Problems We Fix Around Maryland Heights

Between the river bottoms, the creeks and the commercial corridors, Maryland Heights sees both residential and commercial concrete problems.

Concrete driveway slab sunken below the edge of a garage door

Driveways in established subdivisions

In neighborhoods like Arrow Heights, Autumn Lakes, McKelvey Manor and Westglen Estates, driveway panels that have lost support drop at the joints and at the garage.

Patio slab settled away from a brick wall

Patios and walks near creeks

Fee Fee, Dorsett and Midland creeks run through the city. Yards that drain toward them keep soil wet, and slabs on that soil settle and tilt.

Sunken concrete walk at a storefront door

Commercial walks and entries

Around the Westport and Riverport areas, sunken sidewalk panels and entry slabs make trip hazards for customers. Lifting them is fast and keeps the business open.

Warehouse and loading slabs on fill

Much of the low ground was built up with fill. Where that fill settles, floor and dock slabs drop at the joints, and forklifts take a beating crossing them.

Before & After: What Mudjacking Fixes

These are the kinds of slabs we lift every week across St. Louis and St. Charles counties. The slab stays in place; we raise it and fill the empty space underneath.

How Mudjacking Works

Small drilled holes in a settled concrete walkway before mudjacking

1. Drill small holes

We drill a few small holes through the settled slab to reach the empty or soft spots underneath.

2. Pump and lift

A cement-based grout is pumped under the slab. It fills the voids first, then slowly raises the concrete back toward level.

3. Patch and clean up

Once the slab is where it should be, we patch the holes and clean up. Most jobs are finished the same day.

Why Concrete Sinks in Maryland Heights

The Missouri Geological Survey's map of the Creve Coeur area, which covers much of Maryland Heights, shows the Missouri River floodplain here is more than two miles wide, with a water table about 5 to 15 feet below the surface. It shows soft organic clays about 20 feet down in the terrace deposits, and man-made fill up to 40 feet thick.

The city's floodplain page names the Missouri River and Creve Coeur Lake as its two main water sources and notes that much of the area is levee-protected. On the uplands, the same geologic map shows wind-blown silt (loess) up to 100 feet thick, with karst in places.

Wet clays and deep fill both compress over time, and loess washes out when water gets under it. When the soil drops away, the slab follows. Mudjacking fills the void and lifts the concrete back toward level.

 Trustindex verifies that the original source of the review is Google. Nick and his family turned my highly uneven, and very large, concrete driveway and pad into an almost perfectly level sheet. It was amazing to see. Nick and his family were awesome to work with, the price was fair, and the results were amazing. I highly recommend them.

 Trustindex verifies that the original source of the review is Google. Nick and his team were extremely punctual, hard working and completed the task on time. We had almost fifty feet of foundation cracks repaired as well as the driveway mudjacked. Would highly recommend for future work.

 Trustindex verifies that the original source of the review is Google. I wrote a bad review earlier about bad communication. His family was very ill that is why he was slow to get back to me. I ended up hiring them for a large driveway leveling job and it turned out great. Great quality and great pricing. I have referred St. Louis Mud Jacking multiple times since my project and I will continue to use them on my properties. I wish there was a way to remove my old review but I wasn't able to. Great company!!!!

Maryland Heights Mudjacking FAQ

Who fixes the sidewalk in front of my Maryland Heights home?

For public sidewalks, check with Maryland Heights Public Works at (314) 738-2250. Your driveway, walks, steps and patio are yours, and that's where we can help.

Why does concrete settle near the river in Maryland Heights?

The Missouri River floodplain has a high water table, soft clays and a lot of placed fill. All three compress or shift over time, so slabs lose support from below.

Do you lift commercial concrete?

Yes. We lift sidewalks, entries, parking slabs and warehouse floors for businesses. We can often work around your hours so the site stays open.

How long does a Maryland Heights mudjacking job take?

Most driveway and walkway jobs are done in a few hours. Commercial jobs depend on size, and we'll give you a plan with the estimate.
