Case studies using EPS geofoam for mining and energy

August 1, 2018  |  Features

The complexities of the built environment continually challenge the limits of engineering and construction. For infrastructure built-in areas with settlement-prone soils or other hazardous geological conditions, assembling a team of experts to plan for challenges is essential. Industries like mining…
Deploying a geosynthetic mattress ballast layer at an ore-processing site

August 1, 2018  |  Features

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…
Testing a new method for mining-waste storage using polymer-enhanced geosynthetic clay liners

July 31, 2018  |  Features

Geosynthetic clay liners (GCL) and polymer-modified geosynthetic clay liners (PMG) are gaining favor for use in industrial waste disposal and ore-processing applications (Athanassopoulos et al. 2015, Donovan et al. 2016a, Donovan et al. 2016b). The GCL or PMG can be a component of a composite liner …

Monitoring the performance of Louisiana’s first GRS–IBS bridge

June 1, 2018  |  Features

Over the decades, soil mass reinforced by layers of geosynthetics has been used widely and successfully in a variety of earth structures, such as mechanically stabilized earth (MSE) retaining walls, embankments, slopes and shallow foundations. Due to the proven benefits of geosynthetic reinforced so…
Springtime failure of a cold-climate geotextile riprap slope

June 1, 2018  |  Features

Geotextiles play an essential role in geotechnical projects. A significant use for geotextiles is as a separator and filter in drainage and erosion control applications (Holtz 2002). A temporary erosion control application geotextile, such as silt fencing, is used to prevent soil erosion by containi…
Highway deep-patch geogrid applications

June 1, 2018  |  Features

Deep patch is a repair technique that has been widely used on low-volume roads in the Pacific Northwest as a cost-effective mitigation technique to address settlement and shallow landsliding of side-cast embankment fill slopes and natural slopes consisting of weak soils overlying stronger soils (Cue…
A next-gen basin liner solution for the U.S. Army Corps of Engineers
