We were called by a customer in Cincinnati, OH that has a sink hole in their parking lot and wanted us to investigate. We talked through our process and we were hired to inspect the storm piping to make sure that it wasn’t causing the sinkhole.
What Causes a Sink Hole?
Cracks or holes in a sewer pipe can cause the soil around it to infiltrate the pipe. As the sewer pipe keeps carrying away the soil, a void around the pipe can become bigger and bigger. The surface above the void will eventually collapse, creating a sinkhole. On this particular job, the piping was completely in tact. The sinkhole could have been caused from bad backfill when the parking lot was constructed.
What We Used to Inspect the Sink Hole Issue
For jobs that require inspection of pipes and other various jobs that are impossible for one of our Underground Detectives to physically inspect themselves, we use a Cues Tractor Camera that is a camera atop a sort of tri-pod on wheels. We drive the camera down the pipe and are able to move the camera in several directions to get a full view and understanding of what we are looking at and what could possibly be causing issues.
Check out the video of us using a Cues Tractor Camera to investigate for a compromise in the pipe because of the sink hole:
