We Found a Cave

Early February, the Construction EcoServices SWQ team was out assessing a new sand filter rehab project in Central Texas when one of the team noticed an odd looking hole going under the gabion rock wall that stands in the middle of the sand filter. It was plain to see, but a few pebbles were dropped in just to confirm the curious, that the hole was not an animal hole but rather a small opening to a large underground chamber. Understanding the potential danger, Construction EcoServices immediately cordoned off a public safety zone around the sand filter and informed the property owner of the discovery. The stormwater rehab project may be on hold for now, but the story will continue.

While finding new caves around the Central Texas region is not an uncommon occurrence, finding one under developed land is. Despite the excitement of the find, caves can pose a safety concern due to the possibility of their collapse at any given time. In the coming months, engineers will be gather core samples to test the strength of the soil and limestone. Once test results are presented, the county, the property owner and various environmental agencies will determine remediation options.
