From the GMA Techline
Subject: pH and geogrids — I read your Techline section in Geosynthetics magazine and I find it excellent. In the October/November 2008 issue, you mentioned having a study on pH and geogrids in masonry segmental units. If possible, I would like to get a copy of that. (Gabriela, Virginia)
Reply: Thanks for your nice comment. It is really fun to have all types of questions come from all over the world to get a pulse on what’s going on and what things are bothering people. I often wish I had more time to give better clarifications.
That said, Marilyn Ashley will send you the requested paper.
