Repair Uneven Surfaces in Airport Hangars & Runways
Concrete settlement in aviation facilities can create serious operational and safety concerns. When slabs begin to sink around runways, hangars, or service areas, the uneven surface can affect aircraft movement, equipment operation, and overall facility safety. Even small elevation differences can become problematic in areas where precision and stability are critical.
STL Polyjack provides concrete lifting for airport runways, hangars, and aviation facilities using advanced polyurethane foam injection. We lift and stabilize slabs from underneath—no removal or replacement—often saving up to 50% compared to full replacement. Repairs are completed quickly with minimal disruption, helping keep your facility operational.
Why Runway and Hangar Concrete Sinks
Airport runways and hangar floors are built on large concrete slabs supported by soil beneath them. Over time, that soil can shift or erode due to environmental conditions and repeated heavy loads.
Common causes include:
- Soil erosion beneath the slab
- Water infiltration affecting soil stability
- Voids forming under concrete panels
- Heavy equipment and aircraft loads
- Natural soil movement and settling
When the soil beneath the slab loses support, the concrete can begin to settle or tilt. Concrete lifting restores support by filling these voids and stabilizing the soil beneath the slab.
Signs Runway or Hangar Concrete Needs Repair
Settlement problems in aviation facilities often appear gradually but can quickly become operational concerns.
Common signs include:
- Uneven concrete panels on runways or taxi areas
- Slabs settling around hangar entrances
- Gaps forming between concrete sections
- Standing water forming on concrete surfaces
- Cracks developing as slabs shift
- Equipment or aircraft movement affected by uneven concrete
If these conditions continue, the slab may settle further and create additional safety concerns for aircraft and facility operations.
Some facilities that experience settlement around runways or hangars may also see similar issues in other areas of the property. Saint Louis Polyjack also provides lifting solutions for warehouse floors, factory floors, parking lots, and other large commercial slabs. In situations where soil erosion has created empty spaces beneath the slab, soil stabilization or void filling may also be used to restore proper support.

Our Fix: Polyurethane Concrete Lifting
Saint Louis Polyjack uses polyurethane foam injection to lift and stabilize large concrete slabs safely and efficiently. Instead of removing concrete panels, our method restores support beneath the slab by filling hidden voids and strengthening the soil below.
Our process works in three simple steps:
1. Drill Small Access Holes
Small holes are drilled through the slab to reach the empty space beneath the concrete.
2. Inject Expanding Polyurethane Foam
High-density polyurethane foam is injected beneath the slab. The material expands to fill voids, stabilize the soil, and gently lift the concrete back to the proper elevation.
3. Patch the Holes and Complete the Repair
Once the slab is level, the drill holes are patched neatly. The surface is typically ready for use shortly after the repair is completed.
Benefits of Concrete Lifting for Aviation Facilities
Polyurethane lifting offers several advantages when repairing concrete at airports and aviation facilities.
Key benefits include:
- Fast repairs that minimize operational downtime
- Save up to 50% compared to full concrete replacement
- Minimal disruption to runways, hangars, and surrounding infrastructure
- Lightweight material that won’t add stress to underlying soils
- Long-lasting stabilization beneath large, heavy-load slabs
- Improved drainage and smoother, level surfaces for safe operation
Instead of removing and replacing large concrete panels, polyurethane lifting restores the existing slab while correcting the support issues underneath.

FAQs – Airport Runway & Hangar Concrete Lifting
Clear answers about repairing large concrete slabs at aviation facilities.
Yes. If the concrete slabs are structurally sound, polyurethane lifting can raise and stabilize them without demolition. You can learn more about how the repair works on our concrete leveling process page.
The timeline depends on the size of the repair area, but polyurethane lifting is significantly faster than removing and replacing concrete panels.
One advantage of polyurethane lifting is that repairs can often be completed with minimal disruption compared to full slab replacement.
Runway and hangar slabs often settle due to soil erosion, heavy aircraft loads, water infiltration, or voids beneath the concrete.
Yes. High-density polyurethane foam is designed to provide strong support beneath concrete slabs and is commonly used in infrastructure stabilization.
Yes. The same lifting method can repair warehouse floors, factory floors, and parking lots where settlement occurs.
Yes. The expanding foam fills empty spaces beneath the slab and can also be used for void filling and soil stabilization when needed.
