Holes Under Concrete in St. Louis and Kansas City

ground penetrating radar for concrete holes in st. louisThe 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 beneath the concrete. The soil in this area is expansive which means that when it get overly saturated 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.

Hole formation beneath concrete in Kansas City and St. Louis can also occur for several other reasons such as:

  • Erosion - Holes form due to erosion from excessive rainfall or melting snow which washes away the soil.
  • Hydrostatic pressure - Heavy precipitation can also lead to an increase in hydrostatic pressure in the soil.
  • Shifting soil - Soil beneath your concrete may shift for various other reasons causing holes to form beneath the concrete

For whatever reason that holes have formed beneath your concrete, the professionals in the division of Polyjacking.com at Pro Foundation Technology uses can help. We use Ground Penetrating Radar 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 an accurate detection as to where the voids are. GPR is less costly than x-ray detection.

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.

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 completely fill the void
  3. The holes are filled and the site cleaned up
