The Use of Secondary Geogrid Reinforcement in MSE Walls

The Year So Far: Most Popular Geosynthetics Stories

We’ve rounded the corner into the second half of 2017, so it’s time to take stock of what Geosynthetica’s readers have made our most popular geosynthetics stories. Last year was the publication’s biggest year in overall unique readers and in page views, and 2017 has sustained that momentum. We are currently trending another 18% higher on 2016 and 65% greater than in this same period in 2015.... »

Defining Interaction Flexibility for Geogrid-Reinforced Structures

By HUESKER – Key properties in effective geosynthetic reinforcement are adequate tensile stiffness and tensile strength coupled with good interaction behavior. The relatively new technical term interaction flexibility introduces a previously disregarded aspect: the flexibility of the geogrid in a reinforced structure. This property has been shown to improve the interaction between soils and the ge... »

Geotextile-Encased Stone Columns for Railway Passage MSE Walls

Cobramseg is a biennial geotechnical engineering event in Brazil that combines multiple national and international engineering conferences. It’s one of South America’s most important engineering gatherings. At the 2016 edition, Ana Carolina Portela Costa, Ary Franck Baia Cordeiro, Leonardo Campos Dias, and Julián Buriticá García of Dinamiza Consultoria e Engenharia Ltda and Renato Pinto da Cunha o... »

MSE Wall Failures vis-à-vis the Lack of Geotechnical Filters

By Dr. Robert M. Koerner – Since 2001, the Geosynthetic Institute has accumulated data on failures of geosynthetic-reinforced mechanically stabilized earth (MSE) retaining walls. Our MSE wall failures database presently has 301 cases, of which 191 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our past writings and webinars... »

Geosynthetic Reinforcement for Wind Energy

Subsidies and federal energy policies get most of the headlines, but with the increasing size of wind turbines and the scale of wind farms, few sites can be developed without soil reinforcement technologies. Geosynthetics provide the stable base for construction works and long-term access on wind energy sites. On-shore wind turbine hub heights increasingly crest 100m, and some are approaching 150m... »
