The magic of water and geosynthetics
February 1st, 2019
Water is a fundamental issue in many projects using geosynthetics. From erosion control to reservoir liners and covers, from landfill leachate pond barriers to coal ash dewatering, handling water and the effects of water are considerations nearly every engineer employing geosynthetics considers. Geosynthetics can effectively manage water applications of erosion control, reinforcement, barriers, filtration and […]

UV Weathering of Geotextiles Q: My firm is providing construction quality assurance services for a landfill cell expansion. We are having an issue with our contractor and are going to be in a position of having 8 ounces/square yard (271 g/m2) of nonwoven geotextile exposed for a period of time, which exceeds the seven-day limit […]
Deploying a geosynthetic mattress ballast layer at an ore-processing site
August 1st, 2018
New applications of geosynthetics are being found that form from overlaps of existing functions, such as protection, separation, filtration and drainage. One new geosynthetic product, the geosynthetic mattress ballast layer (GBL), was first implemented for an ore-processing waste facility protection application in 2015. The GBL is a geotextile containment system that provides a tubular component […]
Springtime failure of a cold-climate geotextile riprap slope
June 1st, 2018
Geotextiles play an essential role in geotechnical projects. A significant use for geotextiles is as a separator and filter in drainage and erosion control applications (Holtz 2002). A temporary erosion control application geotextile, such as silt fencing, is used to prevent soil erosion by containing the soil and turbid water in a onetime operation. For […]
