MSE wall failures can be mitigated through the use of geotextile filters

April 1st, 2019

For the past 17 years, the Geosynthetic Institute (GSI) has been accumulating data on failures of geosynthetic reinforced mechanically stabilized earth (MSE) retaining walls. We presently have 320 cases, of which 201 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our […]

Geosynthetics opportunities and solutions in shale gas extraction

October 1st, 2018

While natural gas contained within shale rock is geologic and thus ancient by its very nature, the practice of its removal by horizontal drilling coupled with hydrofracking is a relatively recent development (Figure 1). Indeed, these dual technologies are making possible the recovery of huge amounts of natural gas—so much so that one can envision […]

History of geosynthetics use on national forest roads

June 1st, 2017

Introduction The objectives of this article are to document the long history of geosynthetic materials used in the U.S. Department of Agriculture (USDA) Forest Service and other rural roads, to document the many creative and useful ways geosynthetics have been used, and to promote the cost-effective uses of geosynthetics in road projects today, particularly on […]
