Geosynthetic Institute news: Mega waterbags
October 1st, 2017
According to the United Nations (UN), 1.1 billion people in 34 countries have inadequate access to safe drinking water. Furthermore, pollution, global warming and population growth will have continuing negative impacts on the availability of safe drinking water. By the year 2040, the UN estimates that more than 2 billion people in 60 countries will […]
GSI hosts QA/QC of geosynthetics online course

GSI offers webinar on failed MSE walls with geosynthetics
September 25th, 2017
The Geosynthetic Institute (GSI) will offer a webinar entitled “A Data Base and Analysis of 301 Failed MSE Walls with Geosynthetic Reinforcement,” on October 11, 2017, from 11:30 a.m. to 1 p.m. EDT. Mechanically stabilized earth (MSE) walls, berms and slopes with geosynthetic reinforcement have been developed since the 1970s, first using geotextiles and later […]
GSI offers webinar on geosynthetics in erosion control
September 6th, 2017
The Geosynthetic Institute (GSI) will offer a webinar on “Geosynthetics in Erosion Control,” on September 13, 2017, from 11:30 a.m. to 1 p.m. EDT. The estimated cost of landslides in the United States is $2 to 5 billion; worldwide, it may approach $10 billion. The many landslides triggered by surface erosion is a major contributor […]
GSI offers webinar on sand drains, wick drains and geotextile sand columns
August 1st, 2017
The Geosynthetic Institute (GSI) will offer a webinar on “Sand Drains-to-Wick Drains-to-Sand Columns,” on August 9, 2017, from 11:30 a.m. to 1 p.m. EDT. This webinar will begin with Terzaghi’s work (extended by Barron) leading directly to consolidation of saturated soils using the technique of sand drains. It then describes a case history failure resulting […]

Commentary on geosynthetic specifications One can only suspect that the first specification on a given manufactured material came along with or very shortly after the first manufactured product became available. It follows then that some 200 years later, manufactured geosynthetic materials should do likewise. In fact, so-called standards organizations have evolved by publishing the following […]

Liner repair? Pullout tests? Sewn seams? Shear strength of sludges? Geomembrane liner repair Q: I have a facility that has submitted liner repair documentation for the repair of a high-density polyethylene (HDPE) liner for a leachate/stormwater pond at an industrial landfill site. The repairs were performed using either a patch or, for indentations and small […]
Using geosynthetics for macroencapsulation for CCR on-site clean closure
August 1st, 2017
Coal combustion residuals (CCR) have been used for many years in the construction of berms and engineered structural fill applications, including embankments for highways, dikes, and levees. However, large, unencapsulated structural fill projects have become a focus of environmental concerns due to potential leaching of metals and structural failures. Cap-in-place of CCR surface impoundments is […]
GSI offers webinar on in-situ stabilization of slopes using anchored geosynthetics
July 6th, 2017
The Geosynthetic Institute (GSI) will offer a webinar on “In-Situ Stabilization of Soil Slopes Using Nailed or Anchored Geosynthetics,” on July 6, 2017, from 11:30 a.m. to 1 p.m. EDT. The sliding of soil slopes in the form of localized landslides represents an annual loss of $2 to 5 billion in America, not to mention […]
GSI offers webinar on geosynthetic applications in the private sector
June 26th, 2017
The Geosynthetic Institute (GSI) will offer a webinar on “Geosynthetic Applications in the Private Sector,” on June 28, 2017, from 11:30 a.m. to 1 p.m. EDT. In the past, the geosynthetics industry has focused on the major application areas within transportation, environmental, and hydraulic engineering. Yet, many smaller application areas are also important and noteworthy. […]
