This paper presents how geotextiles were used to repair three dams in Texas, Arizona, and Colorado. The geotextile performs different functions in each of these three dams, all of which are dry structures. By Benjamin C. Doerge, Trent Street, John Chua, Rex Stambaugh, and James McHenry.

Geosynthetics manufacturers around the world are trying to find ways to use more recycled plastics in their products, to use greener energy to produce their products, and to find more and better ways to recycle […]
The Geosynthetic Institute has published its list of webinars for the first half of 2021. As we all continue our strange pandemic work schedules, this is a great option for geotechnical engineers needing to get […]
GeoSynthetica was kind enough to track down an interesting case study in the use of geosynthetics at a new de-icing facility at Cleveland’s Hopkins International Airport. Ethylene Glycol and Propylene Glycol are commonly used de-icing chemicals. Most de-icing is done at the gate to avoid flight delays, but it also increases the chance of environmental contamination. In the design of a new dedicated de-icing facility at the airport, geosynthetic clay liners (GCL), Geocells, geotextiles and geocomposites were all used to handle chemical-laden runoff as well as regular runoff during the non-icy times of year. Also there is a problem with high water table and a resulting detrimental effect on the pavement subgrade. This is where the aggregate-filled geocells were used. Read on for the link.
