Product: Geotube® Marine Structures Technology
Application: Sand Dune Cores
Location: Santa Rosa Beach, Florida
The Florida panhandle region suffered heavy damages from Hurricane Ivan in September 2004. The storm generated serious dune erosion in Walton County, Florida. Homeowners faced a critical threat as further erosion would undermine their properties.
Geotube® marine containment technology was selected to rebuild the beach. The Gulf Coast Homeowners' Association installed Geotube® containers to protect up to twelve beachfront properties along approximately 1,000 feet of shoreline [photos 3-4].
Scour aprons were used to protect the Geotube® units and to allow for a more gradual beach gradient [photo 2]. Sand was trucked to the site, and the Geotube® containers were filled with a sand slurry mixture. The 30' circumference units were stacked two high in order to reach the design height of the artificial dune structure [photo 5].
The Geotube® containers were completely buried, contributing to a gentle sloping shoreline and natural appearance [photos 6-7].
The Geotube® installation has been successful. It has survived several tropical storms since 2006.
