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.

① Non-drilling
② No vibration / low noise (electric motor noise)
③ Construction possible in narrow space (minimum floor height 1 m, width 0.5 m)
④ Check all files (100%) bearing capacity
⑤ Verification of foundation proof strength at construction
⑥ Drilling at the basement level 1 or 2 without bracing
Construction after extension of section on side(from the left)
Extension of cross section (reclamation of steel pipe slabs and lower anchor) -> Pressurized frame construction -> Individual compression ->Current pressure-when necessay -> finish
