ABSTRACT:
A method and apparatus for covering substrates such as landfills, sewage, contaminated soil, sludge deposits, compost piles and the like. A protein based solution, preferably mixed from a foam concentrate, is mixed with air in a foam production nozzle and then spread to an approximately uniform thickness over the surface of the substrate.
In an alternative embodiment the present invention also relates to a method for providing a foam covering to substrates such as buildings and other natural and artificial structures to protect such substrates from adverse environmental conditions such as polluted air or water, insects, extreme hot and cold temperatures and toxic vapors or substances.
