Abstract: Woven geotextile grid for earth reinforcement applications. The grid is formed of woven fabric which is coated with a suitable polyvinylchloride or other plastic coating. The fabric is formed of a plurality of spaced-apart pick yarn bundles which are interwoven with a plurality of spaced-apart warp yarn bundles. The pick yarn bundles are held in place in the warp yarn bundles with locking yarns which run parallel to the pick yarns and which are positioned adjacent to the edges of the pick yarn bundles. The warp yarns extend between the pick yarn bundles and locking yarns to lock the pick yarn bundles into place. A plurality of pairs of leno yarns oriented parallel to the warp yarns additionally strengthen the fabric by interlocking with one another in the spaces between pick yarn bundles and locking yarns. The result is a grid which has wide lateral and longitudinal members that lock together to form large interstices through which soil and water may penetrate.
