techgrid geogrids are knitted, and polymeric coated polyester geogrids engineered for demanding soil applications. Superior grades of high tenacity, high molecular weight and low carboxyl end group polyester yarns are formed into a grid structure using a highly sophisticated warp knitting technology and coating technology. techgrid tgu : techgrid tgu series of uniaxial geogrids are available in a range of tensile strength and are suitable for applications, which require strength in one direction. techgrid tgb: techgrid tgb series of biaxial geogrids are available in a range of tensile strength and designed for applications where strength requirement is in both rections. they are used in reinforcement of granular road base, and sub base, area stablization, track bed stabilization, load transfer, platform etc.
