The present invention relates to improved bentonite barrier compositions, and more particularly, to the use of geosynthetic clay liners including these improved bentonite barrier compositions having enhanced low permeability over time in containment applications. A geosynthetic clay liner comprises at least one geosynthetic layer; and a bentonite barrier composition comprising bentonite and a polyanionic starch, wherein the polyanionic starch is carboxymethyl starch.

A coconut material comprising short fibers having a length in a range of 0.5 to 25 millimeters. A method to produce short fibers includes processing coconut husks to separate coir material comprised of pith and fiber from the husks, separating short coconut fibers having a length in the rage of 0.5 to 25 millimeters from the coir material, and packaging the short coconut fibers. The method may include softening the short fibers.

The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials according to the invention are suitable for manufacturing base interlinings which may be used for manufacturing base interlinings for sarking, roofing and sealing membranes, particularly for manufacturing coated sarking, roofing and sealing membranes.

A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure using a computer controlled robotic sprayer that applies a uniform coating. A system for coating secondary containment panels. An apparatus for spraying a coating on a secondary containment panels. The apparatus may be computer controlled and operate automatically to coat the surface of the panel.
