Abstract
An economical method of constructing a means suitable for directing, transporting, or holding water based upon the use of an aqueous liquid silicone elastomeric emulsion to form a membrane on a depression surface which is suitable to direct, transport or hold water. The emulsion, which cures under atmospheric conditions, is sprayed on the depression surface, then dried. The construction is useful as a water harvesting structure with a long, useful life. Such structures are particularly useful in providing water for animals in arid regions.
