Deploying a geosynthetic mattress ballast layer at an ore-processing site
August 1st, 2018
New applications of geosynthetics are being found that form from overlaps of existing functions, such as protection, separation, filtration and drainage. One new geosynthetic product, the geosynthetic mattress ballast layer (GBL), was first implemented for an ore-processing waste facility protection application in 2015. The GBL is a geotextile containment system that provides a tubular component […]
