Eliminate Trip Hazards at Your Strip Mall
Uneven concrete around a strip mall can quickly become a safety and liability concern. When sidewalks, entry slabs, or parking areas begin to sink, they create trip hazards for customers and employees. Sunken concrete can also cause water to pool near storefront entrances, which may lead to additional damage over time.
STL Polyjack provides concrete leveling for strip malls using advanced polyurethane foam injection. Our process lifts and stabilizes sinking slabs from underneath—no demolition or replacement—often saving up to 50% compared to replacement. Most repairs are completed quickly with minimal disruption to businesses and customer traffic.
Why Concrete at Strip Malls Sinks
Concrete around retail properties is exposed to heavy foot traffic, vehicle loads, and changing soil conditions. Over time, these factors can cause the ground beneath the slab to shift or erode.
Common causes include:
- Soil erosion caused by water runoff
- Voids forming beneath sidewalks or entry slabs
- Poor soil compaction during construction
- Heavy traffic in parking areas and drive lanes
- Long-term soil settlement
When these conditions occur, the concrete loses support and begins to sink. Concrete leveling restores that support by filling the empty spaces beneath the slab and stabilizing the soil.
Signs Your Strip Mall Concrete Needs Leveling
Concrete settlement around retail properties often develops gradually, but it can create serious safety concerns if left unaddressed.
You may need concrete leveling if you notice:
- Uneven sidewalks in front of stores
- Raised edges between concrete slabs
- Trip hazards near storefront entrances
- Water pooling along walkways or parking areas
- Cracks forming as slabs begin to settle
- Slabs tilting or separating from nearby sections
If these issues continue to worsen, they can increase liability risks and negatively affect the appearance of the property.
Sometimes settlement at a retail property affects more than just the storefront sidewalks. Saint Louis Polyjack also provides concrete lifting for parking lots, warehouse floors, and factory floors. In some cases, large empty spaces beneath slabs may require void filling to restore proper support and prevent further settlement.

Our Fix: Polyurethane Strip Mall Leveling
Saint Louis Polyjack uses a polyurethane foam injection process to lift and stabilize commercial concrete safely and efficiently. Instead of removing and replacing slabs, our method restores support beneath the concrete by filling hidden voids and strengthening the soil underneath.
Our process works in three simple steps:
1. Drill Small Access Holes
Small holes are drilled in specific areas of the concrete slab to reach the empty space beneath.
2. Inject Expanding Polyurethane Foam
High-density foam is injected beneath the slab. The material expands to fill voids, stabilize the soil, and gently lift the concrete back into position.
3. Patch the Holes and Finish the Repair
Once the slab is level, the drill holes are patched neatly. Most commercial surfaces can return to normal use shortly after the repair.
Benefits of Concrete Leveling for Strip Malls
Polyurethane concrete lifting provides several advantages compared to removing and replacing commercial slabs.
Some of the main benefits include:
- Save up to 50% compared to full concrete replacement
- Fast repairs that help keep businesses open
- Minimal equipment with less impact on your property
- Stabilizes the slab from underneath for long-term support
- Safer for customers and employees
- Clean, level surfaces around storefronts
Instead of closing areas for major construction, leveling repairs the existing concrete while correcting the problem underneath.

FAQs – Concrete Leveling for Strip Malls
Clear answers about repairing commercial concrete and keeping retail properties safe.
Yes. If the concrete is structurally sound, polyurethane lifting can raise and stabilize the slab without tearing it out. You can learn more about how the repair works on our concrete leveling process page.
Most projects are completed quickly and with minimal disruption to customers or tenants. Repairs are often completed in just a few hours.
Concrete surfaces are typically ready for foot traffic shortly after the repair because the polyurethane foam cures quickly.
Concrete often sinks due to soil erosion, water runoff, or voids beneath the slab. In some cases, filling those empty spaces with void filling helps restore support beneath the concrete.
Many property owners prefer polyurethane lifting because it uses smaller drill holes and lightweight material that stabilizes the soil beneath the slab. You can read more about this on our poly leveling vs mudjacking page.
Yes. The same process can be used to repair parking lots, warehouse floors, and factory floors if the slabs are settling due to soil movement.
