The outer membrane forms the actual protective construction and is always under a for the statics necessary positive pressure. Through a built-in viewing window the operations inside can be observed at any time. The actually usable holder forms the inner membrane. This membrane moves up or downwards depending on the filling level. In the gas holder with base plate a bottom membrane seals the storage space to the concrete foundation. With the help of the anchoring ring, the membranes are attached to the foundation.
