Soil Nailing

soil nailingWhen commercial businesses or homeowners are in need of a secure retaining wall, soil nailing is the solution and Matthews Structural Solutions has the best tools from Earth Contact Products (ECP). Soil nailing has been used for many years for a variety of repair jobs. It can be a permanent or temporary solution for multiple uses. Soil nails are used to support and stabilize the soil for plants, tunnels, buildings, and retaining walls.
ECP soil nails consist of a 1-1/2 inch or 1-3/4 inch shaft which is welded along the entire length of the soil nail. They are generally between five and seven feet long, but other lengths can be specially fabricated based on the job.
There are a few points that must be considered to determine if soil nail installation would be the effective solution to the stability problem.

  • Examine ground conditions
  • Discuss the pros and cons of soil nailing in the particular area and situation
  • Other options if soil nailing is ruled out
  • Cost

Soil nails can be inserted into a variety of soil types and conditions, but ideally the soil should be able to stand unsupported for a day or two when vertically cut. All soil nails should be located above the groundwater table, if not the groundwater will negatively affect the excavation site and the bond between the soil and the nail will be broken. If all conditions are favorable for the soil nail(s) to be inserted, the product will provide strong, reliable stability for many years.

The installation process is relatively simple. Holes are drilled into the ground at an angle, then steel bars are placed into the holes for stability. Next, a drainage system is installed with recast face panels or concrete facing. Finally, soil is removed 3 to 6 feet from the ground. These steps are repeated until the desired wall depth is accomplished.

Soil nails offers many benefits:

  • Used in confined areas
  • Repairs retaining walls
  • Installed beneath existing structures next to excavations
  • Stabilizes landslides and slopes
  • Quick and easy installation
  • Cost effective
  • Used for buildings, garages, and sheds
