Conserving Natural Resources Using Geosynthetics

Written By: Cory Schneider, Environmental Scientist, Presto Geosystems Natural resources are finite, or at a minimum, can easily be consumed faster than they can be replaced. As such, the conservation of natural resources is a pragmatic endeavor. Geosynthetics—widely available materials used in construction, civil engineering, and environmental protection—can be useful in promoting the conservation of these resources. When used as intended, geosynthetics can enhance soil properties and reduce the demands placed on natural resources. Types of Geosynthetics Geosynthetics are typically made from synthetic polymers, such as polyethylene, polypropylene, and/or polyester, and are designed to be durable and resistant to weathering and other environmental factors. General groupings of geosynthetics include: geotextiles, geogrids, geomembranes, geocells, erosion control blankets (ECBs), and turf reinforcement mats (TRMs). Geotextiles (permeable) and geomembranes (impermeable) provide separation, while geogrids and geocells provide varying degrees of stabilization and confinement. ECBs and TRMs, made with a combination of natural and synthetic fibers, resist surficial erosion by preventing seed washout prior to germination. Application areas where these geosynthetic materials are used typically include: load support, slope, shoreline, and channel protection, and earth retention. Using Geosynthetics in Load Support Applications to Conserve Natural Resources In load support applications, geogrids, geotextiles, and geocells… Read more »
