Waterproof lining of pressure tunnels and pressure shafts with core rings
There is hollow space between concrete adjacent to rock and core ring; by pneumatic insertion of cement mortar into hollow space, surplus water is removed; filled space becomes prestressed, waterproof mortar ring; patented system produces waterproof lining without use of steel. (See also - n 23 June 10 1950 p 303-7)
