Mining tailings management with geosynthetics
June 30th, 2021
Tailings are by-products, the materials that remain after the process of separating the target mineral from the uneconomic fraction of an ore. They are different from the waste rock or other material that overlies an ore or mineral body, which are displaced during mining without being processed. Tailings can be liquid, solid or a slurry […]
Innovation in the construction industry
June 28th, 2021
By Bryan Gee, director of education and training, Tensar International The construction industry has a long history of innovation. From the Romans paving the way for our modern road infrastructure to technological breakthroughs like the building information modeling (BIM) system, we have come a long way from breaking the wheels of our horse-drawn carriages in rutted dirt roads. […]
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 […]
Anchors, tie-rods and whalers
April 1st, 2021
Q: We are having issues related to obstructions in the reinforced zone of our mechanically stabilized earth (MSE) retaining walls. In the first case, there is a rock outcrop that is limiting the length of the geogrid reinforcement. In the second case, we have a drop-down inlet structure to divert stormwater, which is in the […]
The GMA Techline
August 1st, 2020
Seaming dissimilar geomembranes Q: I kindly request your technical support in the questions below: A nonpolyethylene geomembrane was used in phase 1 of the tailings dam waterproofing system of a gold mine. For the expansion (phase 2), the use of a high-density polyethylene (HDPE) geomembrane is being evaluated. How can the HDPE geomembrane join the bituminous […]
High-strength geocell and geogrid hybrid reinforcement
June 1st, 2020
Compressor station gravel pad on soft subgrade By Sanat Pokharel, Timothy Yii, Marc Breault and Meisam Norouzi Infrastructure development in natural resources rich Alberta, Canada, often encounters very soft ground conditions that pose several construction and sustainability challenges to transportation infrastructure, such as roads, rails and pipelines. As the conventional construction practices may not always […]
