As a result of removing the salt (leaching) beneath the city of Tuzla, there was a large subsidence. Partially subsidence is 12.5 m and a total volume of subsidence is approximately 5,000,000 m3.

Buildings that have been corrected had the differential settlement between two points from 10 to 70 cm. After correction, the building became vertical and in use.
