Geotextile quality issues

April 1, 2024  |  Q&A: GMA Techline

Q: We are performing certified quality auditing (CQA) at a jobsite and having major quality issues with the geotextile delivered to the site. For example, the mass per unit area is low, all mechanical properties are below specification, the permittivity and apparent opening size (AOS) are low. We ar…
Temporary interim covers

April 1, 2024  |  Q&A: GMA Techline

Q: I am writing to inquire if you are aware of any recommendations or guidelines for removal of geosynthetic liners that have been used as temporary interim covers at landfills. We recommend facilities totally take up and remove the temporary cover; however, we have had some recent proposals to run …
Geomembrane testing

April 1, 2024  |  Q&A: GMA Techline

Q: We are a geomembrane manufacturer and have a client who asked us to test an old geomembrane that we sold to them 20 years ago for a surface impoundment. They are also asking us to test a competitor’s geomembrane used at the same site. Can we issue a formal report to a governing agency of result…
Geosynthetics embankment with seismic resilience for highway

April 1, 2024  |  Features

The tectonic movements caused by earthquakes seriously affect the stability of infrastructure. Highways that pass through seismic fault zones are particularly vulnerable to catastrophic earthquake damage because of their long lines and broad areas. The traditional solutions for these problematic sit…
