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.

P1~P7's pier were under the same condition but the damage was focused on P4 pier. The expansion length of the water ways caused by the changing temperatures mostly affected the P4 pier. Without the water way support being changed, the damage extends to P3 and P5. This is the reason why 30% of the aqueducts built with concretes that have 100 years of life expectancy breaks and falls a part within years of construction. The aqueduct was jacked up with a stake and the metal panel was removed due to its corrosion. Instead, we used a highly elastic rubber support that does not corrode to reinforce the aqueduct. The aqueduct is till stable to this day.
