“Tubin’ on the Isle,” a video story posted on ENR.com, the web site of Engineering News Review, features IAI’ latest beach stabilization project and includes an interview with IAI’s Site Superintendent, Larry Leach. The Grand Isle and Vicinity Hurricane Protection Project is underway along the Gulf coast of southern Jefferson Parish, Louisiana and involves beach stabilization using Geotube® (geotextile tube) containers.
IAI crews will install about 30,000 lineal feet of Geotube® containers (geotextile tubes) over the course of the project. The Geotube® containers (geotextile tubes) will be filled with sand and then a sand cover will be placed over them, to create a large dune. The filled Geotube® containers (geotextile tubes) at the core of the dune will reduce erosion of the beach during storms, as they are designed to stay in place even if surging seawater washes away the sand covering them.
The Grand Isle project has many unique features, one of which is the application of a special Polyurea coating that strengthens the fabric of the Geotube® containers (geotextile tubes) and makes them less vulnerable to punctures and damage from UV rays.
The U.S. Army Corps of Engineers, New Orleans District, is financing this project, which is one of the first Corps projects to utilize Polyurea coated Geotube® containers (geotextile tubes). More information and photos of the site can be viewed on the Corps’ Grand Isle Hurricane Protection Project web page.
