Throughout University City, concrete sidewalks and patios are a defining feature, especially near Delmar Boulevard, the University City Loop, and residential streets surrounding Heman Park. Over time, however, even durable concrete can begin to crack, sink, or shift out of alignment. As moisture levels fluctuate and soil conditions change, sidewalks, patios, garage floors, and walkways are often the first surfaces to show visible movement. Because much of University City includes older infrastructure, mature trees, and long established neighborhoods, these issues tend to develop gradually rather than appearing all at once.
In many parts of University City, erosion beneath the slab is a primary cause of concrete settlement. During heavy rain events, which are common throughout the St. Louis metro area, water often moves quickly across yards and paved surfaces. When drainage is not properly managed, that moving water gradually washes soil away from beneath sidewalks and patios. As a result, properties near Centennial Greenway, older neighborhoods along Delmar Boulevard, and homes with aging drainage systems are more likely to experience settlement. Over time, repeated saturation followed by runoff creates empty spaces beneath the concrete. Additionally, tree roots and underground utilities can disturb surrounding soil, further increasing the risk of uneven slabs.
Beyond erosion, soil composition plays a major role in concrete movement throughout University City. The area contains clay rich soils that expand when moisture is present and then contract as conditions dry out. Because this cycle repeats year after year, concrete slabs experience ongoing stress from below. Furthermore, many sidewalks and patios were poured decades ago without modern soil preparation standards. When seasonal freeze thaw cycles are added to these conditions, the soil beneath concrete becomes even less stable, making long term settlement more likely.
Once concrete begins to shift, it rarely settles evenly. Instead, one section of a sidewalk or patio often drops lower than the surrounding surface. As a result, trip hazards can develop near walkways, steps, and entry points. At the same time, uneven concrete alters how water drains around the home. Rather than flowing away, moisture may collect near the foundation or crawl space. Over time, this excess water increases structural stress and can contribute to biological growth inside the home if the issue is left unaddressed.
To correct these issues effectively, slabjacking stabilizes the existing concrete instead of replacing it. For concrete sidewalk and patio repair in University City, MO, small access holes are drilled directly into the affected slab. Afterward, a specialized lifting material is injected beneath the surface. As this material fills voids created by erosion or soil movement, pressure builds gradually and raises the concrete back toward its original position.
Because many University City homes experience settlement related to clay soil behavior and long term moisture exposure, the choice of lifting material is critical. While traditional mudjacking relies on a heavy cement based mixture, Acculevel uses expanding polyurethane foam. This foam reacts quickly, which allows technicians to make precise adjustments during the lift. Once cured, the foam remains lightweight yet durable, helping support the slab while reducing the likelihood of future movement.

For homeowners needing concrete sidewalk and patio repair in University City, slabjacking provides a fast and efficient solution. Since the polyurethane foam cures within minutes, sidewalks and patios near the Loop, Heman Park, and nearby residential streets can often be used again the same day. In many cases, garage floors are ready for vehicle traffic within an hour. Additionally, because the foam is less affected by moisture, repairs can remain on schedule even after periods of rainfall.
Compared to full concrete replacement, slabjacking is significantly less disruptive. Compact equipment allows crews to park along residential streets or in narrow driveways without damaging surrounding landscaping. As work progresses, mature yards and established green spaces remain intact, which is especially important in University City neighborhoods. Meanwhile, the drilling process creates only small access holes that are patched once lifting is complete. Without demolition, homeowners avoid excessive noise, debris, and extended construction timelines.
Because slabjacking works with the existing concrete, it is typically much more cost effective than replacement. Costs are based primarily on the size of the sidewalk or patio and the amount of void beneath the slab, which is common in areas with older drainage patterns. Since demolition and re pouring are not required, labor and material expenses remain controlled. In contrast, replacing concrete can cost significantly more and still leave visible differences in color or texture. Ultimately, slabjacking restores stability and appearance while keeping costs manageable.
We tackled a significant water intrusion issue in Tina's basement by implementing a robust waterproofing solution. The project involved sealing areas where water seeped in and addressing an external crack near the driveway. Additionally, we installed a new drainage system to ensure effective water redirection away from the foundation. The job was completed for approximately $7,000.
