Stabilized Containment Facility Liner

US Patent:
5662983, Sep 2, 1997
Filed:
Aug 30, 1995
Appl. No.:
8/520803
Inventors:
Timothy D. Stark - Urbana IL
Assignee:
Geosynthetics, Inc. - Miami FL
International Classification:
B32B 2714, B32B 312, C02F 100, E02D 1918
US Classification:
428117
Abstract:
The invention relates to a stabilized fluid barrier member and to methods of forming the same. The fluid barrier comprises a first outer sheet member having a top surface and a bottom surface, with a stabilizer element overlying at least part of the first sheet member top surface and abutting the top surface along at least a portion thereof. The stabilizer element contains a plurality of interstitial apertures adapted to contain a quantity of a selectively fluid-impervient barrier material and for substantially preventing displacement of the barrier material from the apertures, notwithstanding the angular inclination at which the fluid barrier member is oriented during manufacture, transport, installation and/or use. The barrier material is chosen for its ability to prevent passage of one or more particular fluids, in liquid or gas form, depending upon the application for which the barrier member is intended. The fluid barrier member of the invention may further comprise an optional second outer sheet member also having a top surface and a bottom surface.

Stabilized Fluid Barrier Member And Method For Making And Using Same

US Patent:
5501753, Mar 26, 1996
Filed:
Sep 1, 1994
Appl. No.:
8/299778
Inventors:
Timothy D. Stark - Urbana IL
Assignee:
Geosynthetics, Inc. - Miami FL
International Classification:
B32B 312, B32B 3114, E02D 1700, E02D 1720
US Classification:
156 70
Abstract:
The invention relates to a stabilized fluid barrier member and to methods of making and using the same. The fluid barrier comprises a first outer sheet member having a top surface and a bottom surface, with a stabilizer element overlying at least part of the first sheet member top surface and abutting the top surface along at least a portion thereof. The stabilizer element defines a plurality of interstitial apertures adapted to contain a quantity of a selectively fluid-impervient barrier material and for substantially preventing displacement of the barrier material from the apertures, notwithstanding the angular inclination at which the fluid barrier member is oriented during manufacture, transport, installation and/or use. The barrier material is chosen for its ability to prevent passage of one or more particular fluids, in liquid or gas form, depending upon the application for which the barrier member is intended. The fluid barrier member of the invention further comprises a second outer sheet member also having a top surface and a bottom surface.
