Shoring Walls

Shoring walls that utilize piling, often referred to as shoring walls, are unique because they stabilize not only the surface soils but also the intermediate soils which may be susceptible to instability. Steel “I” beams or round pipe may be installed by means of drilling or hammering. After the piles are placed, wood timbers are set between the pile elements. These shoring walls are often utilized on slopes, soils subject to liquefaction in a seismic event, or when excavation must be done adjacent to a neighboring property or building.

A geotechnical engineer typically recommends a pile based shoring system only after it has been determined that traditional cast-in-place shoring walls, rockeries, or other shoring wall systems are not appropriate for the site.

The primary components required to estimate cost is:

  • Pile depth
  • Pile diameter
  • Equipment access
  • Equipment size and type required to install the pile elements

A pile based shoring wall system is best because it provides deep seated slope stability while adding minimal weight to the slope. These pile based shoring wall systems are designed and engineered to perform for the long term.
