Product Description
Description of Combined Geogrid with Geotextile
Composite geogrids are a multifunctional geogrid designed to reinforce weak subgrades.They’re manufactured by heat bonding a polypropylene biaxial geogrid to a needle punched nonwoven geotextile or polyester filament nonwoven geotextile.Composite geogrids are used extensively for road and railway construction, landfills, airports and hydraulic engineering and also to provide crack control and pavement reinforcement of roads.
