GSI to host webinar on geosynthetics used in paved and unpaved roads
June 7th, 2021
Beginning in the 1930s, geotextiles and then geogrids have been used in unpaved and paved roads for the purposes of reduced stone base thicknesses and improved serviceability. For use as unpaved road reinforcement, the theory is developed to the point that the benefit/cost of using geotextiles or geogrids can be assessed. This application is very […]

Geosynthetics in action
June 1st, 2021
This issue of Geosynthetics magazine will focus on three distinct applications of geosynthetics. As the first feature, “NPA Geocell for a Railway Line Repair in a Permafrost Region,” describes, it took more than two years to come up with a workable, economical solution for repairs to the deteriorating railway line to Churchill, Man., Canada, the […]
OIT for UV and oven aging
June 1st, 2021
Q: I am contacting you in regard to the requirements for oxidative induction time (OIT) (standard [STD] and high pressure [HP]) in the GRI-GM13 specification for both ultraviolet light and oven aging. Do you need to conduct both OIT tests or just one or the other? A: I would strongly recommend reading the EuroGeo 4 […]
Geotextile under articulated systems in slope armoring
June 1st, 2021
Q: I have a question about the geotextile placed under articulated systems in slope armoring. Based on my understanding, a drainage layer is recommended between the geotextile and the armoring structure, but, since the armoring structure has some spaces in between the armoring blocks, won’t the particles of the drainage layer be washed out through […]
Industry standard for wall drainage systems?
June 1st, 2021
Q: I just watched your recorded video of mechanically stabilized earth (MSE) wall inspection. Thank you for the presentation; it was very informative. I do have a follow-up question for you. I was recently the site engineer for a precast panel MSE wall and now have the opportunity to inspect construction of the wall that […]
GCLs in cold temperatures
June 1st, 2021
Q: I am working on supporting a guide (independent) on what to consider when geosynthetic clay liners (GCLs) are installed in minus temperature regions (e.g., –4˚F [–20˚C]). There is not much published on this, especially independently. This is the only thing I found: Designation: D6102-20Standard Guide for Installation of Geosynthetic Clay Liners5.3.8 The GCL should […]
Useful service life of nonwoven geosynthetics
June 1st, 2021
Q: Where can I find literature on the useful service life of nonwoven geosynthetic fabrics installed in soils? Thank you. A: Nice to hear from you and thanks for your question in regard to the service life of nonwoven geotextiles. Below is a reference that I think is very good. In addition, I have exhumed […]
