core drilling samples

This is our work truck again, this time back in Concord, NC. This particular project involved core drilling through the shop floor of this former transmission shop on church street north. After we get done making a 4" hole in the floor a machine comes in and pounds segments of plastic tube some 30 feet into the ground. This allows the dirt under the old car shop to be sent off to a lab where they will come back with a verdict of whether the ground was contaminated or not by the work of changing truck and car transmissions.
