Abstract
A sprayable composition and a method of protecting material with the composition is disclosed. The composition comprises a bulking/setting material, a water soluble polymer and water to provide a cover layer which, after spraying, is tough, flexible and water-repellent. Other materials such as clay, fibrous material, a foam producing agent and a hardening retarder can be included in the composition. The composition is effective as a cover layer over material such as soil, refuse at a dump site, stockpiled material, a temporary cover for remediation sites, or tire piles.
Claims2
A landfill cover layer formed by a foaming composition comprising:
- (a) a foaming agent,
- (b) a bulking material comprising a clay, the clay being water absorbent, and the clay comprising crystalline, finely divided earthy particles having a particle size within the range of 60 to 325 mesh, and
- (c) a water soluble polymer, the composition when mixed with an aqueous carrier forming a foamed sprayable aqueous slurry suitable for providing a cover layer over a selected landfill material.
