Uneven concrete at schools isn’t just an eyesore — it’s a safety concern. Sidewalk trip hazards, sunken entryways, sloped ramps, and settled interior floors can put students, staff, and visitors at risk while also creating accessibility issues and drainage problems.
Foamjection helps schools restore safe, level concrete without tearing out slabs or shutting down campus areas. Our polyurethane foam leveling process lifts settled concrete from below, stabilizes weak soil, and delivers long–lasting results with minimal disruption. Most projects are completed quickly, allowing schools to keep normal routines in place — whether work is scheduled during breaks, off-hours, or low-traffic times.
Concrete at schools sinks when the soil beneath it loses strength. Common causes include:
As support weakens, slabs settle unevenly and safety concerns increase.
You may need concrete leveling if you notice:
Addressing these issues early helps maintain safe access across campus.
If nearby areas are also affected, walkway & sidewalk leveling, parking lot leveling, or interior floor leveling may be needed to restore consistent height and support across connected areas.
Foamjection levels school concrete by injecting high-density polyurethane foam beneath the slab. The foam expands to fill voids, lift the concrete, and restore firm support below the surface.
Most school concrete leveling projects are completed efficiently, and many areas are ready for use the same day.
Property owners choose concrete leveling because it fixes uneven surfaces without extended closures or replacement. Lifting restores safe pathways while keeping existing concrete in place.
For intact but uneven concrete, leveling is often the most practical solution.
Concrete lifting can be used in many areas across a campus, including sidewalks, entryways, ramps, courtyards, drop-off zones, drive lanes, stair landings, and other exterior concrete surfaces where settlement affects safety or accessibility.
Concrete at schools often settles due to soil erosion, poor drainage, freeze-thaw cycles, and years of foot traffic or service vehicle use. Over time, these conditions create voids beneath slabs, causing walkways and paved areas to sink or shift.
In most cases, yes. Leveling costs less, takes less time, and avoids extended closures.
Most school projects are completed in hours rather than days. The exact timeframe depends on the size and number of affected areas, but the process is designed to minimize downtime and disruption.
Yes. We coordinate closely with school administrators to plan work during off-hours, school breaks, or low-traffic periods whenever possible. The goal is to improve safety without interfering with classes or campus activity.
The leveling process uses small access points that are sealed after lifting. These patches are subtle and far less noticeable than saw cuts, trenches, or replacement joints.
Yes. Re-leveling concrete can restore proper slope, helping water drain away from walkways, ramps, and entrances instead of pooling where students and staff walk.
Correcting uneven slabs removes abrupt height changes that commonly cause trips and falls. This helps schools address safety concerns proactively and reduce potential liability.
Absolutely. The polyurethane foam is engineered for structural support, cures quickly, and does not wash out or break down over time. Once installed, it becomes an inert, stable material beneath the slab. It is waterproof and eco-friendly.
