Sinkholes

I-4 Maitland Boulevard Sinkhole Stabilization

GEC served as geotechnical engineer of record for the largest individual sinkhole grouting project in U.S. history. Located in Orange County at the intersection of Interstate 4 and Maitland Avenue, the project included the stabilization of a 325-ft diameter sinkhole by installation of over 200 grout injection pipes to depths of up to 350 feet and injection of approximately 40,000 cubic yards of cement grout. After grouting, the sinkhole was further stabilized by placement of a 25-ft high surcharge fill with settlement monitoring
