Soil Nails

Soil nails are part of our geotechnical service offering and are a highly versatile method for slope, embankment, and landslide stabilisation. Soil nails are a cost-effective ground stabilisation technique that can be used in a wide range of ground conditions with low environmental impact.

Soil nails are one of the geotechnical engineering techniques we specialise in.

We offer a complete range of hollow bar and self-drilling soil nails and strands, solid bar and double corrosion protection ground anchors, installed using tracked or wheeled Soilmec and Casagrande drilling rigs.

Key rig capabilities:

  • Rig loadings: 1.5–34 tonnes
  • Bore diameter: 50–300mm (nails)
  • Maximum depth: 35m (nails)
  • Working load: 10–500kN (nails)
  • Maximum depth: 25m

What are the advantages of Soil Nails?

  • Lightweight and corrosion resistant
  • Can be stressed accurately to required capacities
  • Minimal soil disturbance with low environmental impact
  • Ideal for sites with difficult and restricted access because the rigs that are utilised are usually smaller
  • Temporary works and platforms requirements are reduced
  • Often a more cost effective and faster solution for temporary excavation support
  • Soil installation and excavation can progress concurrently

Common Uses

  • Soil nailing uses grouted steel bars to reinforce in-situ soils to create a gravity retaining wall for permanent or temporary excavation support allowing soils to stand at steeper angles than they would naturally.
  • To treat slope failures or slip circles.
