14 GSI Fellows Announced for 2018 – 2019

Ten years ago, the Geosynthetic Institute (GSI) Board established the GSI Fellows program. Since then, the institute has provided an exceptional level of support to student-centered research and development projects involving geosynthetics. The investment helps spur the next generation of understanding with geosynthetics and the impact of the program is recognized in the field today. The 2018 R... »

Carbon Footprint Advantages of HDPE Geomembranes

By José Miguel Muñoz Gómez – High-density polyethylene liners are renowned for containment performance in landfills, mining, wastewater, and other vital sectors. Less discussed but meriting evaluation is the superior carbon footprint rating that HDPE geomembranes provide versus traditional barriers like compacted clay. A 1.5mm (60-mil) HDPE liner can provide a seal similar to 0.6m of high-quality,... »

Reinforcing Megastructure Foundations with Geosynthetics

The 74m-high reinforced soil structure at the Sikkim Airport (India) is one of the largest geosynthic megastructure projects in the world.  The 50m-high reinforced, vegetated wall at the Shennongjia Airport in Hubei Province (China) is another. Both projects have been engineered with Maccaferri soil reinforcement solutions. MAKING MEGASTRUCTURE DESIGNS POSSIBLE High-performance geogrids reinforce ... »

Slideshow of Whales - Geomembranes

A Primer for Preventing HDPE Geomembrane Whales

By Ian D. Peggs, Ph.D., P.E., P.Eng  – There continue to be failures of HDPE geomembrane lining systems in waste water treatment plant (WWTP) lagoons and farm manure ponds. These geomembrane whales, which are bubbles that develop under the geomembrane, are generally caused by leakage through the liner, the inability to remove leakage, the generation of methane, and the subsequent inability to vent... »
