Remember, for every action there is an equal and opposite reaction. The reaction to a live load is the pumping of fines into the stone above. Over...- OldGeoGuy

The lack of knowledge about geosynthetics is astonishing. The strongest common geosynthetics are geotextiles (GT). Geogrids (GG) fall off the chart pretty quickly. The FHWA and most knowledgeable people use the term "Geosynthetic Reinforcement". For slopes and walls, it doesn't matter what...- OldGeoGuy
