What Is Soil Nailing?
The soil nailing process is a relatively fast and involves fewer construction materials than what's needed with other methods used for the same purpose. With this type of installation, the soil is retained, and anchors are used. It's typically done with wire mesh and shotcrete to with slope stablization during building or foundation preparation. The soil nail technique is used to retain the natural slope during the construction process. Soil nail installation may also be used as a permanent solution in situations where it's important to prevent slope failure or erosion on a long-term basis. Make sure you hire a trusted soil nailing contractor to help with your soil nailing needs to make sure it gets done properly the first time.

What Are Common Uses for Soil Nail Installation?
Soil nail installation can be temporary or permanent. It can be done at just about any point during building or foundation preparation when it becomes evident that a slope will need to be secured to prevent safety risks. There is no need for structural elements below the bottom area of the excavation, allowing for a faster soil nail installation process and more versatility with possible usage. The soil nail method may be used for the following reasons:
- Excavation support: Removing soil to clear a site and prepare it for a new construction sometimes results in slopes that could present certain risks for construction personnel. One solution is to create a soil nail set-up.
- Landscape & Slope Stabilization: Landscapes or other areas of residential or commercial properties sometimes become unstable from exposure to the elements or because of issues with gravity. Slope reinforcement is a quick and easy way to provide some extra reinforcement.
- Retaining wall repair: Retaining walls sometimes become damaged over time from normal wear and tear or the deterioration of materials, especially wood. Soil nails can sometimes be installed to re-stabilize a retaining wall, which may eliminate the need for complete replacement.
What Is The Soil Nailing Process?
At Keystone Foundation Repair, we typically use hollow bar grouted rock anchors or helical anchors to provide the needed slope reinforcement. The soil nailing process is usually done in incremental stages. It's a convenient process that can be done from the top down as excavation work progresses. With excavation support, soil is usually excavated in 3-6 foot stages. After each stage, holes are drilled into the exposed face. Steel bars are then placed into the holes. After grouting the bars in place, a drainage system is usually installed before the application of shotcrete facing.
Bearing plates are attached to the heads of soil nails. This process is repeated until the preferred wall depth is reached. What will be left is an area of reinforced ground that's safe for construction workers or builders. A similar process is used for retaining walls. The equipment typically used is small enough to get into areas with limited access. With retaining walls and other existing steep slopes, soil nails can be installed from working platforms that are crane-suspended.
What Kind of Precautions Are Taken?
One of the most appealing benefits of soil nailing is that nail lengths, location, and inclination can be adjusted should any obstructions be encountered during foundation or building preparation (e.g., underground utilities, boulders, piles, or cobbles). Because installation involves several soil nails, it's easier to make adjustments with layout or nail placement. These adjustments can usually be made without compromising the site's safety, integrity, or stability. Soil nail wall use is also beneficial for the following reasons:
