Cover Structure Abstract of the Disclosure Described is a universally usable and durable cover structure formed of a framing and a flexible plastic sheet. The framing consists of a metal grid structure onto which the flexible plastic sheet is shrunk or welded. In a preferred embodiment shown in fig. 3, a thinner and closer-meshed mesh structure overlays the grid structure 1. This embodiment employs an upper and a lower plastic sheet 2a and 2b, respctively, connected to one another in such a manner that the grid structure and mesh struct- ure are sealingly enclosed therebetween. Further described are preferred uses of the cover structure as for the construction of water retention structures.
