Commentary on attribution and referencing in technical papers
April 1st, 2018
In presenting written technical information in academic papers and presentations, including in geosynthetic papers, as well as conference proceedings and presentations, it is established practice for the author to attribute references, data, charts, tables, graphs, photographs, illustrations and concepts back to the initial originator/developer, who under law is the copyright holder to the work simply […]

IGS-NA supports Geosynthetics 2019 The North American Chapter of the International Geosynthetics Society (IGS-NA) is proud to support the Geosynthetics 2019 conference, which is organized by the Geosynthetic Materials Association, to be held Feb. 10–13, 2019, at the Marriott Marquis […]
GSI hosts webinar on geosynthetic drainage materials
February 8th, 2018
The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Geosynthetic Drainage Materials: Applications, Design, Installation and Performance,” on Feb. 24, 2018, from 11:30 a.m. to 1 p.m. EDT. Geosynthetic drainage materials consist of a drainage core (geonet or geospacer) with geotextiles bonded to one or both surfaces. Their in-plane flow capacity is equivalent to 12 […]
GSI hosts webinar on wave management in geomembranes
January 31st, 2018
The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Wave (or Wrinkle) Management for Proper Deployment of Geomembranes,” on Feb. 14, 2018, from 11:30 a.m. to 1 p.m. EDT. An intrinsic property of all exposed geomembranes is that they expand and contract depending upon ambient temperature. During times of elevated temperature, waves (also called wrinkles) […]
GSI offers webinar on pond liners
January 16th, 2018
The Geosynthetic Institute (GSI) will offer a webinar entitled “Pond Liner Design and Performance,” on Jan. 24, 2018, from 11:30 a.m. to 1 p.m. EDT. The first ponds were lined with geomembranes in the 1930s, and the application has grown enormously to the present. For example, of the many kinds of contained liquids, hazardous types […]
GSI offers webinar on geosynthetics in hydraulics
January 3rd, 2018
The Geosynthetic Institute (GSI) will offer a webinar entitled “Geosynthetics in Hydraulic Applications,” on Jan. 10, 2018, from 11:30 a.m. to 1 p.m. EDT. By 2040 it is estimated that two billion people (25% of the world’s population) in 60 countries will have inadequate freshwater. This alarming prediction suggests that water must be hydraulically transferred […]

December 12th, 2017
The Geosynthetic Institute (GSI) will offer an online course entitled “Quality Assurance/Quality Control of Geosynthetics in Waste Containment Facilities,” on Jan. 30 and 31, 2018, and Feb. 1, 2018, from 11:00 a.m. to 12:30 p.m. and from 2:00 p.m. to 3:30 p.m. EST. This online course focuses on the quality assurance/quality control (QA/QC) of geosynthetics […]
GSI offers webinar on MSE wall, berm and slope construction inspection
December 1st, 2017
The Geosynthetic Institute (GSI) will offer a webinar entitled “Mechanically Stabilized Earth (MSE) Wall, Berm and Slope Construction Inspection,” on December 13, 2017, from 11:30 a.m. to 1 p.m. EDT. The inspection (aka monitoring) of MSE wall, berm and slope construction using geosynthetic reinforcement is essential for building a safe and durability system. Such inspection […]
The durability of exposed geomembrane covers
October 1st, 2017
The most frequently asked question by people in the geosynthetics world is how long is the anticipated lifetime of geosynthetics. So much so that of the more than 3,000 questions submitted to the GMA Techline since it began in 2004, 591 (19.7%) have been on lifetime, aka durability. Of these, 49% were on buried lifetime, […]
GMA Techline

Welding HDPE to PVC and more Q: I would appreciate any input you have on these questions: Can a high-density polyethylene (HDPE) geomembrane (GM) be welded to a PVC geomembrane? I am looking to connect a geomembrane to a building foundation. Based on some research, I have found the following options: bolt the geomembrane to […]
