Hark Drilling brings over 20 years of experience in soil nailing in the Intermountain West. We have the equipment and expertise to complete projects from start to finish.

Specialized Soil Nail Solutions for Slope Stabilization

At Hark Drilling, we provide expert soil nail wall services, ideal for both commercial and residential projects, as well as public infrastructure developments. Soil nailing is essential for ensuring structural stability and safety in projects involving excavations near property lines or existing buildings. Our soil nail walls are specifically engineered to stabilize slopes and prevent soil displacement during deep excavation works, offering a robust and reliable solution for challenging construction environments.

What Are Soil Nails?

Soil nails are a versatile solution used in both temporary and permanent applications. The process involves drilling and installing high-strength all-thread bars, grouting the holes, and applying a facing consisting of mesh and/or rebar with shotcrete/gunite.

Hark Drilling has the expertise to install soil nails using both the cased drilling method and hollow bar installation, depending on ground conditions. This allows us to offer the right solution for any soil type or stability requirement.

How Soil Nails Work

Soil nails act as retention nails, providing soil retention by stabilizing hillsides and retaining walls. They can be used to support roads and bridges, making them a practical solution for infrastructure projects, both temporary and permanent.

The Soil Nail Installation Process:

01

Preparation

Creating a pad for machinery when necessary, excavating down to different lifts of the soil nail wall.

02

Drilling

Installing soil nails, with either solid bar or hollow bar options.

03

Concrete Work

Grouting the holes, applying rebar and wire mesh, and spraying shotcrete.

04

Finishing Touches

Providing architectural finishes and completing final grading.

Soil Nails in Action

Soil nail walls can function as:

Shoring: Temporary or permanent shoring for construction projects, such as building foundations, bridge abutments, or retaining walls.
Remediation: A remedial solution for existing retaining walls that can help avoid a full rebuild.
Slope Protection: Preventing erosion and landslides, offering slope stability.

Soil Nails | Frequently Asked Questions

What equipment is used?

Specialized machinery for soil nailing, including standalone machines and attachments for excavators.

How much space is needed for soil nailing?

Space requirements vary by technique. Solid bar nails need a level machine, while hollow bar nails offer more reach with an excavator attachment.

What is a solid bar soil nail?

A solid bar of metal is installed in either an open hole or in a cased hole, with grout pumped around the nail inside the casing, then the casing is extracted.
