Rolling Out the Green Carpet

This article describes how geosynthetics can provide versatile and cost-effective solutions to a variety of civil engineering problems. Applications include erosion control; drainage; soil stabilization and retention; roadway pavement, base, and subgrade reinforcement; water containment; and green roof systems. Three reasons for the increased use of geosynthetics are suggested: (1) greater awareness by the civil engineering community, both in design and specification; (2) cost-effectiveness; and (3) continued focus on environmental and green issues. Geosynthetics can be inexpensive to transport, can often accommodate the use of local or onsite materials, and are durable products that provide a significant design life or extend the design life of the structure. Although cellular confinement products have been available to the marketplace for 30 years, its use has increased recently because it offers green solutions for slope and channel protection, earth retention, and load support. With increased emphasis on Leadership in Energy and Environmental Design (LEED) certification for buildings, geosynthetics such as moisture barriers, moisture adsorption composites, drainage nets, nonwovens, and geogrids can provide key components in green roof systems, adding as many as six LEED credits. Civil engineers who lack familiarity or experience designing with geosynthetics can find ample online resources such as product data, project case studies and design aids.
