1. Jack Pile (JP) — Foundation reinforcement
NET No. 629 Foundation
Korea E&C’s innovative press-in approach reinforces foundations with minimal excavation waste, vibration, noise, and dust. Applications include foundation reinforcement, underground/above-ground extension support, unequal/differential settlement restoration, parallel movement & rotation, and structure lifting/lowering. Related methods: JPG and grouting.
- Minimal vibration / noise / spoil vs conventional underpinning
- Real-time load monitoring for documented QC
- Suited to occupied and vibration-sensitive sites
- English NET materials available in Resources
2. Bolt Tension (BT) — Seismic & structural reinforcement
NET No. 682 lineage Structural
Columns
Non-adhesive column strengthening without surface chipping patterns typical of older methods.
Slabs
Effective slab strengthening with non-adhesive concepts for occupied structures.
Beam shear
T-beam shear reinforcement above the neutral axis with enclosure where possible.
Column removal
Open space by removing central columns and reinforcing beams / adjacent columns.
3. Vibration-free rock breaking
Specially designed cylindrical hydraulic jacks fracture rock without the vibration and noise profile of conventional blasting — ideal for urban and sensitive facilities.
4. Two-way excavation method
Pulls from both sides without traditional massive temporary support layouts, improving constructability and economy on qualifying projects.
