The building went through fundamental reinforcement with 50 micro pile, but the tilted degree was 1/74, a grade E standing, before restoration. The stake supports the weight shifted to the foundations of the building, so it must be assessed with compression test rather than tension test, and must be able to support twice the weight of the actual load. The tension strength was probably over 100 ton, but the axial strength was less tan 30 ton. The building that had 160mm of drooping was raised to 145mm and was restored to 1/786, grade A. However, the building could not be restored to a vertical state as the micro pile was holding the building with a lock anchor.
