PRODUCTSFor Better Construction & Safer Future


Soil Nailing is a construction technique that stabilizes slopes by inserting reinforcing bars into the soil and anchoring them to the soil strata.

Installation Flow

Bearing Type Nail Fixture (Wedge Grip Nut)

A bearing type nail fixture that consists of a wedge and a fixing nut maximizes connection with a steel bar and increases the life span of a reinforced slope or a retaining wall.


  • Easy installation that can reduce construction period
  • Using a wedge and a nut, a bearing plate seats tightly on slope surface and increases adhesion force
  • Assembled without screw threading the end of a steel bar
  • Compatible with various sizes and shapes of steel bars

Liner Screw & Nut (Ring+L/S)

After drilling a borehole and inserting a steel bar, a liner screw and a nut can easily be assembled with a steel bar fixing nut tightly to a bearing plate.
