Rock Anchors

Rock and Soil Anchors
Thomas Drilling & Blasting has many years of experience installing and testing rock and soil anchors and tie-backs for ground support for the foundation, tower, construction and wind power industries.

Rock Anchors
Rock anchors are high strength steel bars or strands that are drilled and grouted into the underlying rock and are generally used to:

  • Anchor uplift forces
  • Anchor tipping forces
  • Stabilize slopes foundations rock walls and cuts

Soil Anchors
Soil anchors are high strength steel bars or strands that are drilled and grouted into the underlying soil and are generally used to:

  • Support structures for excavations such as sheet pile walls, soldier piles and lagging.
  • Transfer external forces to the ground; e.g., wind, earthquake
  • Stabilize material or excavated slopes

Both types of anchors can be pre-stressed.  A design load tension is put on the anchor.  In order for the anchor rod or the structure it is anchoring to move the tension force has to be exceeded.
