Video: The Pine Hills Sinkhole – Central Florida, 2002
On June 11, 2002, a 150-foot wide and 60-foot deep sinkhole opened up in Pine Hills, Florida and came within a few feet of two 3-story appartment buildings. Geotechnical and Environmental Consultants (GEC) was contacted by the owner of the site to design emergency temporary and permanent stabilization measures to protect the buildings. The sinkhole mitigation began with a chemical stabilization of the soil using an injected sodium silicate chemical grout (incidentally, that work was performed by John N. Puder, Inc., recently acquired by Moretrench) to stabilize the sands underneath the buildings and adjacent to the sinkhole. After some GPR surveys, borings and other investigations, final sinkhole repair consisted of a 200-foot long wall omprised of interlocked 36-inch diameter steel tubular piles that extended to a depth of 50 feet. They were driven by Giken America Corp. using the press-in method which helped to avoid damage to the adjacent buildings. The entire stabilization was completed within 1-month of the initial sinkhole collapse! Click through for this fascinating video. (Photo credit Giken America Corp. by way of GEC)

40 Foot Sinkhole in Tenn. Stadium Endzone
A large 40 foot wide by 40 foot deep sinkhole opened up just outside the endzone of Austin Peay State University’s Governors Stadium in Tennessee. The stadium is currently undergoing upgrades for next year’s football season. Sinkholes are not unexpected on Austin Peay campus, and the video below shows one example of how the University has actually incorporated the remediated sinkholes into the landscaping. Representatives from the University and the contractor expect the sinkhole will be filled without any problems.
