Holes Under Concrete in St. Louis and Kansas City

The concrete in the St. Louis and Kansas City area can experience problems such as holes and voids beneath the concrete due to the changing moisture content in the soil. The soil in this area is expansive which means that when it gets oversaturated it will heave and expand and when dry, it will shrink. This causes holes to form beneath the concrete leading to the concrete to crack and settle into these holes.

GPR Detects Holes Under Concrete

We use Ground Penetrating Radar (GPR) to detect underground holes. It is fast, accurate, and inexpensive. GPR uses a high-frequency radar antenna and advanced signal software to accurately locate the holes underneath the concrete. GPR also detects embedded utilities, conduit, PVC, rebar, and tension cables. This allows for accurate detection as to where the voids are.

GPR units are portable and provide an instant location. When the GPR accurately detects these voids, then the experts can start the repair process and get the holes filled and the concrete level and stabilized.

Hole Repair in Kansas City and St. Louis

Polyjacking.com uses high-density polyurethane foam to fill the holes beneath the concrete, leveling and stabilizing it. Using polyurethane trucks with the right poly equipment, this method is relatively simple and much more cost-effective than replacing concrete.

This method includes:

  1. Drilling a small 5/8" hole in the affected concrete.
  2. The polyurethane foam is injected into the hole into the void beneath the concrete. This polyurethane foam expands to fill the void.
  3. The holes are filled and the site cleaned up.
  4. Polyurethane foam has a short hardening time so the surface is ready for use in about 15 minutes. The polyurethane material is impervious to water, preventing future problems.
