A quarry in Atlanta, Georgia is being transformed into a water storage facility to ensure the city has a 30+ day supply of raw water to use in the event of a natural disaster. To ensure the quarry was safe for all personnel during the conversion process, GeoStabilization was contracted to improve its geologic stability. Our rockfall technicians, utilizing limited-access equipment, have been working 60-hours a week to remove loose rock and anything that might become dislodged as a result of weather or anticipated vibrations from the tunneling. Our personnel’s work will ensure that the crews installing the quarry’s new tunnel system will be safe from rockfall during the project’s entire scope. The reservoir is expected to be full by the end of 2018, with a park built on the surrounding property over the next 15 years.
A variation of karst sinkhole grouting is the grouting of mined coal seams and workings located below existing infrastructure that exhibit the potential to propagate to the surface and cause sinkholes and/or subsidence.
