A concrete structure is lined with a statically self-supporting glass shell composed of shell segments which are themselves joined together by sealing strips. In a pipe embodiment of the invention, the shell segments form a ring spaced from the concrete body with the spacing being filled by a backfill mass so that a compressive prestress is provided to the arch shape. When used in a container, the shell may be a laminate of two or more glass layers bonded full surface together.

Fluid-impervious structure and method of making same

A narrow wall or slotted wall which is introduced into a geological substratum or foundation, including a sealing wall composition contained therein, and at least one sealing wall plate which, for example, is constituted of glass. The sealing wall plate which is fixed in the sealing wall composition or, the sealing wall plates, possesses or possess devices for the detection and recognition of leakages. These devices can be constituted from hollow profile members which are connected with the sealing wall plates; in essence, can be integrated therein.
