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 mortar pillar placement was reinforced with indenting a stake on he weak ground, but when the soil was placed on top, the conduit box settled with the placed mortar pillar and the stake. Indentation of 216 steel stake of 1610ton was done to raise and reinforce. The soil on top of the box was removed during the reinforcement to decrease the weight of the reinforcement and placed again afterwards. The surrounding friction of the mortar pillar stake and the box made the reinforcement a hard process.
