Repairing Gabion Walls with Soil Nails
Access Limited teams use soil nailing to repair and stabilize gabion walls when possible. Soil nailing involves inserting thin reinforcing bars, or nails, slightly downward into slopes at various depths determined by engineers.
We use a compressed air cannon called the Soil Nail Launcher™ to shoot 20-foot steel or fiberglass nails into the soil at 250 miles per hour. This innovative technique can be much more economical than using conventional soil nailing procedures or creating concrete gravity walls.
This method of repair works best when the facing of the retaining wall is still somewhat intact. If it isn’t intact due to erosion or crumbling rock, we’ll use soil nailing alongside other methods of stabilization, and we may carefully restack the salvaged stone.
