It’s long been said that investing in land is smart because “they aren’t making more of it.” In general, this is true. Mitigation strategies create more habitat, but not more land—except in the case of an artificial island. The project noted below was originally published on Geosynthetica in 2013, but its relevance remains. More of these islands are in planning,...

Engineering work generally requires long hours in the field, in the lab, or simply chained to a computer inputting data, translating data, and assembling reports. To some, the concentration required for this type of work might suggest that it is not conducive to creative endeavors, that it is something of the opposite. That's far from correct. The complexity of...

While geosynthetic clay liners (GCLs) are composite materials by design, the newer wave of multi-component GCLs are enhancing the performance of GCLs in a range of applications in a way that represents a significant jump for an already refined engineered materials area. The use of special polymeric coatings on a GCL is providing longer services lives for these materials,...

One of the longest running and most respected geosynthetics CQA courses is getting a digital refresh, with so many practitioners limited in their ability to travel right now. TRI Environmental's renowned classes on QA/QC in geosynthetic installations and with compacted clay liners and geosynthetic clay liners will be offered for the first time in an online format June 1...

The International Geosynthetics Society Vice President, Dr. Nathalie Touze, delivered an inspiring Giroud Lecture at the 11th International Conference on Geosynthetics (September 2018, Seoul). The lecture’s topic was “Healing the World: A Geosynthetics Solution,” and since that event Dr. Touze has delivered the lecture in different forums around the world. Now, the IGS has released a video of the full...

Electrical leak locations provide invaluable insight into the integrity of a geosynthetic lining system. All geomembrane-lined containment facilities should be tested for leaks before going into service. Early detection of leaks allows for swift and effective repair pre-service, which protects the engineer, contractor, owner and in many cases the environment. Even covered geomembranes can be surveyed, including after a...

The International Conference on Innovative Solutions for Geotechnical Problems was originally scheduled for June 2020 in Istanbul; but, in light of the global coronavirus outbreak, organizers have announced moving the conference to 2021. The new dates for ISGPEG 2021 have not yet been communicated to the general engineering community. Instead, the organizing committee has indicated that authors who had...

The International Geosynthetics Society has released a new ebook for Earth Day! The short publication, Preparing the Ground for a Brighter Future, is based upon IGS Vice President Dr Nathalie Touze’s Giroud Lecture. In Dr. Touze’s lecture (Healing The World: A Geosynthetics Solution), she highlights the UN Sustainable Development Goals, climate change, and philosophy while emphasizing what we can do...

Originally published as "Comparative Life Cycle Assessment of Two Design Alternatives for a Geosynthetic Reinforced Bridge Abutment" in the GeoAmericas 2016 proceedings, Dr. Melissa Beauregard, Dr. Arunprakash Karunanithi, and Dr. Caroline M. Clevenger's research provides an accessible, well written account of life cycle assessment with two major design alternatives. Specifically, they look at geosynthetic mechanically stabilized earth (GMSE) and...

From 20 - 22 April 1977, the International Conference on the Use of Fabrics in Geotechnics was held in Paris, France. This watershed event included a paper from engineer Dr. J.P. Giroud in which he coined two terms that have become central to the field of geosynthetics: "geotextile" and "geomembrane." The Paris gathering, which would later be recognized as the...
