Tufted Geotextile With Intermediate Diverter Tufts For Increased Resistance To Infill Displacement

摘要

A tufted geotextile cover system, comprising a backing sheet tufted with first tuft lines of tufts on a first spacing and second transverse tuft lines of tufts on a second spacing greater than the first spacing to dispose the second tufts intermediate opposing pairs of the first tuft lines that define interstices for receiving infill, the tufts in the second tuft lines increasing resistance of the infill to displacement and dry flow movement in response to loading on the geotextile overlying a surface for covering a ground site. A closure system is disclosed using the tufted geotextile as a component overlying an impermeable geomembrane for resisting inflow of water below the ground surface.
