Abstract
Abstract A liner or cover system is provided, which can at times have at least a portion of its area exposed to wind and/or ground fluid action and consequent damage, and which is held in position against dislodgement and therefore against damage by said action by an anchoring means or structure. The system is held anchored from under it at a plurality of loci by said anchoring means or structure which exerts at each said loci a force at least equal to the maximum force of wind and/or ground fluid expected to act at any time at said loci independently from any force acting at any time at any other of said loci of said liner or covering. Also, there is provided a method for constructing said system which includes among its steps bringing together at least two sections or laps to be incorporated to form said liner or cover, joining the laps to form at least a portion of said liner or cover or system, and anchoring said liner or cover from below it at a plurality of loci to form at least a portion of said liner or covering. The loci at which anchoring is effected are distributed at least across the exposed area of the liner or covering, preferably in a grid-like pattern. Several embodiments of the system are included within the description, drawings and the claims. In use, the system can contain, retain or fend off fluid or liquid from contact as with the ground or other substance to be covered as in an impoundment, channel and/or in the prevention of evaporation of a liquid, e.g., water, or collection of a fluid, e.g., geothermal steam, or e.g., storage of agricultural products.
