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.
