A method of constructing a means suitable for directing, transporting, or holding water is disclosed. A silicone elastomer coated cloth (31) is used to cover the surface of a depression suitable to direct, transport, or hold water. Cloth can be coated by laying it upon a surface convenient to a depression suitable to direct, transport, or hold water. The cloth is coated with a liquid silicone elastomeric composition curable at atmospheric conditions. The composition cures to an elastomer having a modulus which provides sufficient flexibility to the coated cloth so that the coated cloth will assume the contour of the depression, the coated cloth being impervious to liquid water. After curing, the coated cloth is moved to the depression and placed into the depression to cover the surface of the depression. The coated cloth is then bonded at any seams and the perimeter of the coated cloth is stabilized. The method yields a structure that is economical to manufacture, yet has a long, useful life with a high reliability in such applications as catchments, irrigation ditches, and holding ponds. |
