Abstract: The present invention provides a system and method for protecting buildings from damage due to seismic waves. The system comprises a bed of sand contained between two layers of polymer membrane, upon this sand bed a rests a first concrete slab, this first concrete slab supports, through a plurality of coil springs and shock absorbers, a second concrete slab. The structure to be protected is attached to the upward facing surface of the second concrete slab. In the event of an earthquake, the sand bed acts to slow the propagation of seismic waves, while the plurality of springs and shock absorbers isolates the structure from ground movements caused by the waves.

Abstract: 1°—A bed of sand, who are also a natural shock-absorber; when an eathquake with upthrust, it fight by balancing at the opposite side of upthrust and lating at the construction to be solid. 2°—Above the bed sand a first slab concrete iron are disposed springs and shock-absorbers. 3°—Shock-absorbers are organized in the center of construction and extremity ordering in triangularly (named by himself TRIANGULATION). They are for principal functions slow down—detain of masses movments the furious shocks, dodge at the construction savage of springs unbending. 4°—Springs are here to absorb oscillations, flutters, earthquake at 8, 9 RICHTER scale waves P and also wind provoke by waves S 425 km/h. 3a.4a.—The springs and shock-absorbers work agreement for stability of construction. They can be also take a different distance between them. 5°—The second slab concrete iron independent is holding springs and shock-absorbers; it is building foundation.
