Ground anchors

Ground anchors

Ground anchors are highly versatile methods for slope stabilisation and earth retaining structures, which can be used in a wide range of ground conditions with low environmental impact.

Benefits

  • Lightweight and corrosion resistant
  • Can be stressed accurately to required capacities
  • Minimal soil disturbance, with low environmental impact, ideal for sensitive sites

Applications

  • Slope stabilisation
  • Retaining structures
  • Difficult access sites

Technique

Ground anchors are typically installed into pre-drilled boreholes, although some are self-driving, and grouted into place. Boreholes are formed using rotary bored and rotary percussive rigs, down-the-hole hammers and augers, depending on ground conditions. Multi-strand anchors are post-tensioned after installation and temporary anchors may be de-tensioned and removed.

Capability

Van Elle offers a complete range of hollow bar and self drilling soil nails and strand, solid bar and double corrosion protection ground anchors, installed using tracked or wheeled Soilmec and Casagrande drilling rigs.
