Levees Reinforced With Geosynthetics Perform Exceptionally Well
Levees reinforced with geosynthetic materials in New Orleans withstood Hurricane Katrina and flooding. Geosynthetics stablize the ground, reduce use of traditional stabilizers, conserve natural resources and provide a reliable building base.
"Both the St. Charles and Jefferson levees were loaded (filled by the storm) during Katrina and performed exceptionally. They were stable and the geosynthetic was inherent to their strength,” said John Bivona, Deputy Chief, Engineering Division, New Orleans District, U.S. Army Corps of Engineers.
Geosynthetics are a family of civil engineering materials that are often used in infrastructure construction. Many durable polymers (plastics) common to daily life are found in geosynthetics. Introduced in the 1960s, geosynthetics have proven to be versatile and cost-effective ground modification and environmental protection materials. Most of these materials come in roll form and are delivered to the site in trucks. The U.S. Army Corps of Engineers was one of the first agencies to put geosynthetics to use, and geosynthetics are now used in nearly all areas of civil, geotechnical, environmental, coastal, and hydraulic construction.
“Geosynthetics allow us to design and build in areas that would be very difficult if using only natural materials,” said John Henderson, chairman of the Geosynthetics Materials Association (GMA). “The soft soils in and around the Gulf Coast region can pose some very challenging problems. Geosynthetics allow for construction of levees, roadways, and commercial projects by strengthening the base on which these structures are built.”
“No reason to say that they [geosynthetics]
