This project involved a large sinkhole that opened up at a horse racetrack in Ocala, FL. Sinkholes like this one might appear gradually, but in many cases, they form suddenly. If a sinkhole like this one were to open up under a home, business, or parking lot, it could cause major damage or injury. Quick-forming sinkholes are dangerous because they do not provide time to react.
This sinkhole, as you can see from the pictures, was large enough to cover over half of the track, and had very deep sides. Because of the sinkhole, the track was unsafe for horses.
After our team inspected this sinkhole, we determined that it could repaired by filling in the sinkhole with soil and injecting a grout solution to compact the soil around the sinkhole and stabilize the area.
