Tricosafe 30 Geogrid As the subsoil can only absorb very low or no tensile forces, the slope angle and load-bearing capacity of the soil are limited. TRICOSAFE® geogrids absorb the occurring tensile forces and enable steeper slopes and more resilient foundations and counteract ground failure. Application Securing exposed slope fronts until vegetation has taken hold, steep slopes, supporting structures, embankment foot reinforcements and foundation reinforcements are typical areas of application for TRICOSAFER® geogrids.
