PRODUCTSFor Better Construction & Safer Future
Overview
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.
Features
- 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.
