The smart maintenance strategy: Paving fabric is a long-lasting, economical choice for road repair
July 24th, 2009
Shedding new light on the economic value of incorporating a paving fabric interlayer in pavement in maintenance projects. By Jamie Swedberg This newly released work is a comprehensive study of pavement repair materials and methods. It examines maintenance treatments on 370 roads in Greenville County, S.C., in the 1997-98 maintenance year. The work is called […]
Agricultural applications for geosynthetics
July 24th, 2009
Containment as a requirement As water becomes more and more scarce—thus, costly—providing a barrier against high rates of water seepage loss will become a requirement in more than just arid and semiarid regions. In addition to water conservation, wastewater containment is an essential component in protecting water and air from pollution caused by animal waste. […]
Water and wastewater applications of geosynthetics
July 24th, 2009
Need for secure containment Containment of water and wastewater in ponds may be needed for reasons as wideranging as seepage avoidance to prevention of groundwater contamination. Whatever the reason for lining a pond, the use of geosynthetics in these types of applications is growing. Geomembranes create an essentially impermeable barrier that prevents any liquid that […]
Canal lining with geosynthetics
July 24th, 2009
The problem As clean water becomes more difficult to acquire, the need for secure water containment and transport grows. This problem is exacerbated by urban water demands and increased agricultural production in remote areas around the world. There is a demand for vast amounts of water in areas where water does not naturally exist at […]
Silt fence applications for geosynthetics
July 24th, 2009
Sediment control Silt fences, or temporary sediment control fences, often are the most visible form of erosion or sediment control on a construction site. Used properly, silt fences can limit the transport of eroded soil from disturbed areas. A silt fence is not an erosion control device; it is a sediment control device. As soil […]

Dealing with difficult sites In the past, when dealing with difficult sites for construction purposes, the conventional practice was limited to either replacing the unsuitable soils, or bypassing them with costly deep foundations. Additionally, the age-old problem of land scarcity and the need to rebuild aging infrastructure in urban areas, increased realization of seismic hazards, […]
