Pillar reinforcement technology does not require surface chipping and anchor drilling.
Slab reinforcement technology effectively reinforces with non-adherence method
This is a T-shape beam reinforce-ment technology that reinforces the shear strengthening steel to above the neutral axis
The central pillar was removed to maximally expand the central space, then the surrounding pillars were reinforced
The non-vibrating rock crushing technology crushes without noise or vibration with specially made hydraulic jacking device
Most of the existing methods uses installation of strut and using the strut to push, but Korea E&C's technology pulls from each side to improve construction and cost.

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.
