PODCAST: Perspectives on Puncture Protection for Landfill Lining Systems

On by Geosynthetica
News and Articles

The field of geosynthetics has often been defined by how these materials improve the performance and economics of a particular site or application. One of the ways that geosynthetics achieve such goals is through rigorous testing to ensure proper selection of a material. However, engineering approaches are often driven by a market’s level of infrastructure development and regulatory readiness. Thi... »

MSE Wall Failures vis-à-vis the Lack of Geotechnical Filters

On by Geosynthetica
News and Articles

By Dr. Robert M. Koerner – Since 2001, the Geosynthetic Institute has accumulated data on failures of geosynthetic-reinforced mechanically stabilized earth (MSE) retaining walls. Our MSE wall failures database presently has 301 cases, of which 191 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our past writings and webinars... »

Geosynthetic Reinforcement for Wind Energy

On by Geosynthetica
News and Articles

Subsidies and federal energy policies get most of the headlines, but with the increasing size of wind turbines and the scale of wind farms, few sites can be developed without soil reinforcement technologies. Geosynthetics provide the stable base for construction works and long-term access on wind energy sites. On-shore wind turbine hub heights increasingly crest 100m, and some are approaching 150m... »

The Geotechnical Poetry of Mary Nodine

News and Articles

Geotechnical engineering requires a lot of waiting. You wait on calls, test results, the weather. You wait on a construction activity to finish, on software to complete extremely complex models, on site assessments to be signed off on. You wait in labs and airports, on calls, in lobbies. So what to do with all that waiting? Sometimes, you let the mind wander. It may just take you to geotechnical p... »

Best Practices for Minimizing Geomembrane Wrinkling

By Catrin Tarnowski –  Geomembrane wrinkling occurs, but it can be minimized. “Lay flat” geomembrane installations are quite possible, as they are documented all over the world. Truly, we can achieve this; yet, geomembrane wrinkling still happens. How does wrinkling occur? It is connected to numerous decisions made in design, product selection, and installation procedures, and with boundary condit... »
