Abstract
A method of constructing a means suitable for directing or holding water is described. A depression suitable to direct, transport, or hold water, such as a water catchment or irrigation ditch is covered with cloth, any seams are fastened together, then the cloth is coated with a liquid silicone elastomeric composition curable at atmospheric conditions. The coated cloth edges are stabilized. The method yields a depression having a surface impervious to liquid water that has a long expected life due to its resistance to damaging effects such as weathering and exposure to wandering animals.
