Soil Nailing

Soil nailing is a construction technique that is used to improve the stability of slopes and excavations. It involves the installation of steel or fiberglass rods into the soil, which are then grouted in place. Soil nailing can be used to reinforce both natural and man-made slopes.

It is an effective way to stabilize slopes that have been damaged by erosion or stormwater runoff. Soil nailing is also frequently used in the construction of retaining walls and other structures. The technique can be used to strengthen both new and existing structures. When properly installed, soil nails can provide a high degree of support for many years.

When is Soil Nailing Necessary?

Soil nailing is often used on slopes or embankments that are at risk of collapse. It can also be used to support structures built on unstable ground, such as cliffsides or sinkholes. In some cases, soil nailing may be used as an alternative to traditional foundation systems.

While it is typically more expensive than other methods, it can be less disruptive and faster to install. As a result, soil nailing is a versatile technique that can be used in a variety of situations.

Soil Nailing Techniques

Soil nailing is the technique of strengthening the soil to give it more stability. The process involves hammering steel bars into the soil, hence the name “soil nailing”. This process of soil nailing provides a resisting force against slope failures. The process is faster than other similar methods.

The procedure starts by drilling into the soil where the “nail” steel bar is going to be placed. After the drilling is completed, the exact depth must be provided by a geotechnical engineer, then the nail is inserted into the drilled hole. After that is completed, it is grouted into the soil to create a structure similar to a gravity wall.

My Foundation Repairs uses Earth Contact Products (ECP), for soil nailing. These ECP soil nails are 1-1/2″ and 1-3/4 square bars with both 6″ or 8″ helix flights. The shaft lengths are 5′ and 7′ with an ultimate tensions strength of 70,000 lbs. and 100,000 lbs. The shaft is a solid bar.

Soil Nailing For Foundation Repair

When you have soil failure, you will have foundation problems. The soil needs to be stabilized and secure in order for a foundation to be stable. Most foundation problems are caused by soil failure.

My Foundation Repairs installs ECP soil nails to stabilize the soil. These soil nails are installed in an evenly spaced close geometric pattern. When installing a soil nail stabilization project, the soil nail installation and the excavation must be accomplished in incremental depths of 4 to 6 feet until the final depth is accomplished. Immediately following the incremental excavation of the soil and the soil nail installations, the vertical face of the soil is covered with a steel reinforced coating.

Soil nails are passive structural elements and are not tensioned after installation. The soil nail gains pullout resistance from within the sliding soil mass in front of the slip plane and the stable soil mass located behind the slip plane. The geometric system of soil nail placements creates an internally reinforced soil mass that is stable. Figure 4 shows a sketch of a typical soil nail installation. Soil nails are not tensioned after installation. They gain pullout resistance from within the sliding soil mass in front of the slip plane and the stable soil mass located behind the slip plane.

Each soil nail has a great number of helical plates. These helical plates are evenly spaced along the entire length of the shaft (a tieback anchor only has a few helical plates attached).

Soil Nailing Contractors

The installation of soil nails is a specialized process that requires the use of heavy equipment and trained personnel. As a result, many homeowners and businesses hire soil nailing contractors to perform this work. Soil nailing contractors typically have a team of workers who are experienced in operating the equipment and performing the necessary excavation.

In addition, soil nailing contractors usually have a good understanding of the local geology and soils, which is essential for choosing the right type of nails and ensuring that they are installed correctly. As a result, hiring a reputable soil nailing contractor is often the best way to ensure that your project is completed safely and successfully.
