Zusammenfassung:FIELD: building, particularly for increasing load-bearing capacity of foundation built on earth base in the case of foundation load increase or in the case of natural structure of earth base damage. ^ SUBSTANCE: method involves digging out pit and arranging reinforcement means under foundation bottom along the full length thereof. Microtunnels filled with hardening material are used as reinforcement means. Microtunnels are arranged so that sides of each microtunnel are in contact one with another or with foundation bottom. Microtunnels are formed by driving drilling auger in ground under foundation bottom along the full auger length. Drilling auger has through channel for pumping hardening material into microtunnel formed past auger end after extraction thereof out of ground. ^ EFFECT: increased load-bearing capacity. ^ 2 dwg
