Abstract:
A geocomposite with a geonet and a geotextile. The geotextile has a nonwoven fabric layer and a woven fabric layer, with the nonwoven fabric connected by needle-punching to the woven fabric whereby fibers of the nonwoven fabric extend through and beyond the woven fabric, and the woven fabric and fibers of the nonwoven fabric extending through the woven fabric are bonded to one side of the geonet.
