How it works

What to know about soil nailing, and when it's the right call.

A soil nail starts as a bar, typically single threaded, drilled into the hillside. Grout is then installed around it to encase the bar and lock the nail in. When the grout hardens, it creates additional skin friction, the grip between the grout and the surrounding soil, which helps hold the nail where it is. The nails are tied into a rebar cage or mat, and a concrete wall or a shotcrete wall (concrete sprayed into place) is built to tie them together into one system. The closest comparison is the similar helical tieback system, since both reach into the ground behind the face; the difference is that a soil nail is drilled and grouted. Soil nailing is one of the hillside stabilization methods we use, alongside drilled soldier piles.

The symptoms that usually lead to soil nailing are on the hillside repair problem signs page, alongside the other signs that point to the same underlying cause.

Installation Process

How we install soil nailing.

Step 01

Free evaluation

A specialist evaluates the slope and the signs of it moving, then explains the findings.

Step 02

Design for the slope

The soil nailing plan is part of a slope stabilization design made to fit the slope's current condition.

Step 03

Drill the bars

A single threaded bar is drilled into the hillside for each nail.

Step 04

Grout the nails

Grout is installed to encase each bar and lock the nail in place. As it hardens it adds skin friction that helps hold the nail.

Step 05

Tie them together

The nails are tied into a rebar cage or mat.

Step 06

Build the wall face

A concrete wall or a shotcrete wall is constructed, tying all of the nails together.
