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 foundation of one site that was constructed with 500 PHC stake (100ton/stake) with dimension of 42m in depth, 120m in length (7.5m between the pillars) was settling. The foundation of this storage was very solid with N=100/30 on the 5-10m area, but the 30m below had N=15-30/03. The foundation was reinforced with load factor of 50ton (216x8.2) stake, pressurizing each with 100 ton. The stake was 35-45m indented. the JP indented stake and all of the indented stake's strengths are automatically measured by the pressurized gauge during indentation process, and thus does not need a separate load test. However, we completed a load test on the first indented stake and found that it was appropriate with 50 ton of load.
