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.

This was a reinforcement constructions done on Dongsongjeong station that was settled due to matt basic construction on the weak ground. The most certain solution in dealing with a weak ground is to drive in a stake through the hard ground and building a building on top of that. This station previously reinforced by adding cement on the hole that was drilled on the outside of the building through the ground once the building started to tilt. However, the building continued to tilt 1mm every week. The problem was fixed by indenting steel stake inside the building.
