After a short retrospect on possible elasticity the intended purpose of stress controllers as rock support elements in shotcrete construction is described. Different types of stress controllers are briefly explained. The successful development as well as the technical versions of the stress controller type - HONEYCOMB - is explained in detail.
Experiences in first use at Tauerntunnel with its system components are presented. Further possible fields of application and developments are elaborated.
