  • Low permeability geosynthetic clay liner and method of manufacture thereof
    Patent number: 5776547
    Abstract: A geosynthetic clay liner with a low permeability or controlled permeability intermediate sheet is provided. The liner includes two outer sheets with two layers of bentonite and an intermediate sheet disposed therebetween. The intermediate sheet may be rippled or deformed to enhance the structural stability of the liner. The intermediate sheet may be chosen from a material with low or ultra-low permeability characteristics or may be chosen from a material with controlled or directional permeability characteristics.
    Type: Grant

  • Geosynthetic clay liner with modified edges for improved sealing
    Patent number: 5529438
    Abstract: A clay liner is provided for use in constructing low permeability barriers in the bottom of landfills and man-made bodies of water. The liner is provided in the form of a layer of bentonite preferably disposed between a primary carrier sheet and a cover sheet. At least one outer edge of either the cover sheet or the primary carrier sheet is made from a material that allows substantial bentonite migration through or includes a slit that enables bentonite to migrate through while the remaining areas of the cover sheet or primary carrier sheet are fabricated from a fabric that does not permit substantial bentonite migration. When two liners are disposed adjacent to each other in the bottom of the landfill or pond, the two liners are overlapped so that the more open portion of one liner engages the adjacent liner. Upon activation, the bentonite migrates through the more open fabric to create a seal between the two adjacent liners. The result is a self-sealing geosynthetic clay liner system.

  • End fabric woven fence
    Patent number: 5201497
    Abstract: A barrier fence comprising a leno fabric woven from thermoplastic yarns, and a series of stripes of a thermoplastic resin in a warp direction integrally adhered to the leno fabric, having gaps therebetween, wherein the stripes adhered to the leno fabric have a Tensile Strength in the warp direction at least equal to or greater than that of the gaps.
