PCT No. PCT/EP87/00794 Sec. 371 Date Aug. 15, 1988 Sec. 102(e) Date Aug. 15, 1988 PCT Filed Dec. 18, 1987 PCT Pub. No. WO88/04710 PCT Pub. Date Jun. 30, 1988.A hydraulic buffer, filled with a compound having the behaviour of a liquid to a certain extent, mounted beneath the foundation of buildings or other structures in order to sustain the structures during earthquakes. The buffer is made from reinforced flexible material and consists of two parallel circular plates (1,2), on the circumference connected to each other by a torus (5), in such a way that the torus and the drum-like space between the circular plates communicate freely, while the axis of the torus is upright, in order to permit the buffer to accommodate relative transverse movement between the circular plates.
