A plant for pressurized storing of natural gases includes one or more rock cisterns with a rock cover where the rock mass has a weight at least corresponding to the inner maximum cistern pressure against the cistern roof. The inner rock surfaces (2) which are reinforced through anchoring bolting or similar are lined with a sprayed concrete layer (4-8), a sealing layer including at least one reinforced (14) and one unreinforced plastics layer (16) being provided thereon via a binding layer (12). |
