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. The second sheet member overlays at least part of the stabilizer element such that at least a portion of the second sheet member bottom surface abuts the stabilizer element. After positioning the various components of the barrier member in abutting stacked relation, they may all be bonded together along at least a portion of their abutting surfaces to form an interconnected laminate wherein the stabilizer element is in contact with and bonded to both the first and the second outer sheet members.
