Geosynthetics for severe geotechnical problems
High Strength Geotextiles
High Strength Geotextiles incorporate both polypropylene and polyester components. High Strength Geotextiles are used in environments where the subgrade is extremely weak and high tensile modulus is necessary. High Strength Geotextiles provide great drainage and flow properties to support an aggregate base that is free of hydraulic saturation.
Geogrids are used for two primary reasons. They provide tensile load support on soil slopes, berms and MSE walls. Grids also allow multi-directional long term stabilization on roadways and parking lots.
Uni-Axial Geogrids were developed to reinforce steep slopes and support MSE or retaining walls. Uni-Axial Geogrids are comprised of either polyester or polypropylene yarns woven into an interlocking grid. These geogrids have unparalleled strength in one direction. This one-directional strength makes it purposeful in tie back applications for MSE walls, berms, and other geosynthetic structures. Uni-Axial Geogrid is available in assorted levels of tensile strength and aperture size.
Bi-Axial Geogrids were designed to provide a simple-to-install, high strength product to stabilize roadways and job sites. When designed and installed properly, the geogrid essentially reduces the thickness of the aggregate base by confining soil and stone particles. This confinement prevents lateral shearing, allowing the tensile load to spread over a broader plane, ultimately decreasing the pressure applied to the subgrade level. Bi-Axial Geogrids are available in a number of different tensile strengths and aperture sizes.
