    Patent number: 4222685
    Abstract: A method of providing a substantially impermeable lining to the bottom of an earthen pond using native soil. Such soil is classified and formed into a slurry containing fine particles of predominately five or less micron size. The pond bottom is covered with a first layer of the slurry which is allowed to dry to a point where large crack patterns develop. The cracks are filled with a second layer of the slurry. More layers may be applied to form a final lining having the desired permeability for the particular application.
