Concrete Problems We Fix Around Cottleville

Cottleville mixes an old creek-side town center with a lot of newer construction. Most of the settling we see comes from wet bottom land and from soil that was moved to build new homes.

Driveways in newer subdivisions

With the population nearly doubling in ten years, many Cottleville driveways sit on lots that were cut, filled and graded not long ago. As that loose soil packs down, panels drop and the joints open into ridges you can feel when you pull in.

Patio slab settled away from a brick wall

Patios near the Dardenne Creek bottoms

Yards that slope down toward the creek stay damp for days after a storm. A patio on that soft ground tends to sink on its low side and starts sending rain back toward the house.

The soil packed in against a new foundation keeps settling for years. A stoop sitting on it leans out and leaves a gap at the door where water runs in behind the step.

Walks and entries at Old Town businesses

Old Town along Highway N, the former Boone's Lick Road, is the city's historic business district. A customer entrance or side walk that has sunk an inch is a trip risk, and lifting it is far quicker than tearing it out.

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 Cottleville

The city's own history says early travelers were often stranded at the Dardenne crossing because the creek kept overflowing and the bottom lands turned to mud. Two grist mills were already running there by 1804. That same low, wet ground still runs through part of town.

The Missouri Geological Survey's map of the O'Fallon quadrangle reaches down to Cottleville at its southeast corner. It describes the higher ground as two layers of wind-blown silt (loess), with the lower Roxana layer carrying more clay. Where shale lies under the loess, the map says water perches on top of it. Near Dardenne Creek the map shows silty floodplain deposits up to 130 feet thick, with groundwater only 5 to 15 feet below the surface.

Silt and clay that stay wet lose strength, and runoff slowly carries fine silt out from under the edges of a slab. Mudjacking pumps a cement-based grout into that empty space and raises the concrete back toward level. Pointing downspouts and yard drainage away from the slab keeps the new support in place.

 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!!!!

Cottleville Mudjacking FAQ

Who fixes the sidewalk in front of my Cottleville home?

The City of Cottleville says it repairs streets, curbs and sidewalks throughout the year, using city staff, contractors and the St. Charles County Highway Department. You can report a public sidewalk that needs work through the city's online work order form (choose Streets) or by calling City Hall at (636) 498-6565. Your driveway, walks, steps and patio are yours to maintain, and that's where we can help.

My house is fairly new. Why is the driveway already sinking?

New lots are usually graded, and soil gets pushed in around the foundation and under the driveway. That loose fill keeps packing down for years after the concrete is poured. The slab itself is often fine. It has just lost the soil under it.

Why does concrete settle near Dardenne Creek?

The creek bottoms are silty, the groundwater sits close to the surface, and the area has a long history of overflowing. Soil that stays wet gets soft and washes out more easily, so slabs near the creek lose support faster than ones on higher ground.

Can you lift concrete at a business in Old Town?

Yes. We lift entry slabs, walks and small lots for businesses, and most jobs are quick enough that you can stay open. If a walk is part of the city's public sidewalk, check with the city first, since the city handles those repairs.

Do you serve the areas around Cottleville?

Yes. We work in St. Peters, O'Fallon, St. Charles, Lake St. Louis, Wentzville and the rest of St. Charles County, plus St. Louis County.
