Landfill Closure Erosion Control

| Capping and closing a municipal solid waste (MSW) landfill can be a civil engineering challenge. The goal is to eliminate any need for further erosion control work on the site to ensure that the landfill keeps its structural integrity. True, landfill owners are required to adhere to EPA's post-closure rules as defined by Subtitle D of the Resource Conservation and Recovery Act, which include maintenance of the leachate collection system, groundwater monitoring system, methane gas monitoring system—and, germane to erosion control activities, the final cover system. But having more structural work done after a landfill has been capped and closed can be costly and can damage the owner's reputation. ... READ MORE

How to Make a “Floating Road”

| Robert Barrett of Carthage Mills went on in the late 1970s to join forces with the US Army Corps of Engineers in the development of geotechnical fabrics. From their tests in Mobile, AL, fabrics for architectural designs and construction on soft soils were developed, and a whole new frontier was opened for the future uses ... READ MORE

Canal Case Study: Geocomposite Liners

| The Snake River Valley of eastern Idaho didn’t become an agricultural center until well after the Civil War. The Homestead Act, which became US law in 1862, brought settlers determined to farm to the area. The Homestead Act allowed any citizen of the US who was the head of the family or over 21 years ...

Geosynthetics: Defining Eight Categories

| Geosynthetics are amazing products. They range from sheets that are less than a millimeter thick to three-dimensional cells. They may be pervious or impervious, woven, knitted, stitched, matted, or extruded. Made of polymer materials such as polyolefin, polypropylene, high-density polyethylene (HDPE), and low-density polyethylene (LDPE), they’re thinner, lighter, and easier to install than sand, gravel, ...
