Reinforced levees to induce seepage path around geogrid layers?

February 1st, 2022

FIGURE 1 Reinforced levee expansion over existing dike using geosynthetics The Geosynthetic Institute (GSI) has been asked many times regarding several applications for different styles of geogrids if reinforced levees will induce a seepage path adjacent to and around geosynthetic layers. At this point, GSI has no case histories where it can quantify such behavior […]

New standard will support measuring quality of cement in geosynthetic composite mats

June 29th, 2020

A new ASTM International standard will aid engineers and specifiers looking to understand the quality and strength of cement contained in geosynthetic cementitious composite mats (GCCMs). ASTM’s geosynthetics committee developed the new standard, which is needed to allow for a consistent industry method for the application of compression strength in GCCMs. GCCMs are flexible, concrete-impregnated […]
