What Sinkholes Are
A sinkhole is the result of soil loss or migration below the surface. Water finds a path through a defect in the stormwater system, removes the supporting soil, and leaves a void that cannot carry loads. The solution is a combination of source repair and engineered reconstruction of the subgrade so the surface and the system both regain strength.
Why Sinkholes Form
A sinkhole is a symptom of undermined ground. It occurs when subgrade material is displaced and the pavement or turf above no longer has support. On developed sites this is commonly linked to stormwater assets such as pipes, catch basins, or outlet control structures. Repair means closing the leak path, rebuilding the base with engineered materials, and restoring the surface.
What to Do When You Spot a Sinkhole on Your Property
If you notice a depression, soft spot, or opening on your property, it’s important to stay clear of the area and contact a stormwater professional right away. What looks small on the surface can hide a much larger underground void, creating serious safety risks.
Our team inspects the site using advanced diagnostics, addresses the source of soil loss, and restores the surface with engineered materials built for Philadelphia’s climate. Acting quickly prevents costly damage, keeps your property compliant, and ensures your stormwater system performs for years to come.

Stabilization That Meets PWD Expectations
Every stabilization we complete is built around local standards and real site conditions. Philadelphia clay soils, utility crossings, and heavy traffic all influence the way a repair should be designed. We address these factors up front so the fix is durable and inspection ready.
From first inspection to final resurfacing, our process targets safety, performance, and compliance. You receive a clear scope, photo documentation, and a repair that holds up through repeated rain events.
Our stabilization workflow:
- Isolate the area and protect pedestrians and vehicles
- Diagnose the failure using camera surveys and test pits
- Correct the stormwater defect that allowed soil migration
- Rebuild the base with appropriate gradation and compaction testing
- Restore the finished surface and provide closeout documentation
Common Questions About Sinkhole Repairs
What causes sinkholes to form near stormwater structures?
Most are caused by water finding a path through a pipe joint, structure wall, or connection point. Over time, flowing water removes surrounding soil, creating a void beneath the surface.
How do you repair and stabilize a sinkhole?
We begin by diverting water away from the affected area. Next, we inspect the stormwater system to locate the source of soil loss, repair the defect, and rebuild the base with engineered materials.
How quickly should I have a sinkhole repaired?
Every rain event can make the problem worse. Rapid response ensures the repair remains smaller, more affordable, and more effective. Delays give stormwater more opportunities to erode the soil and widen the cavity.
Can you fix a sinkhole without replacing the entire stormwater system?
Yes. Most sinkholes can be fixed by repairing the specific defect and restoring the subgrade, without replacing the full system. Our process repairs the defect, restores the ground, and prevents recurrence, which often eliminates the need for complete system replacement.
