FIELD: construction.
SUBSTANCE: method to strengthen foundation bases in seismically dangerous zones includes indentation of injectors into soil and supply of a hardening mortar through them under pressure first along the periphery of the strengthened area until closure of adjacent sealing zones, and after hardening of the mortar - inside the produced contour. Previously the strengthened area is broken into equal parts of the rectangular shape. After supply of the hardening mortar along the periphery of the strengthened area they supply a mortar along the periphery of each part of the rectangular shape also until closure of the adjacent sealing zones. After hardening of the mortar they supply the hardening mortar inside the produced contours of the rectangular shape, besides, injectors inside contours are installed in the staggered order.
EFFECT: higher reliability of a foundation due to strengthening of a foundation base with increased coefficient of attenuation of seismic oscillations.
