terrafix® has published a video of a “TBX Biaxial Geogrid Strength and Confinement Demonstration.” It’s a concise, visual demonstration of how and why geogrids are so effective at improving soil stability under load. The demonstration was conducted in a controlled warehouse and utilized a 12,000+ lb telehandler with an axle weight that exceeded 8,000 lb. See it here and view more... »

By Sam Bhat – The Canadian National Railway (CN Rail) wanted to build an additional 6-track extension at the Transcona yard in Winnipeg, Manitoba. Heavy rail cars were expected to pass over this extension area, but the site was not situated on ideal soils for further railway development. CN Rail discovered quickly that the track extension project would need to be delayed while it returned to the e... »
