Drilled elements installed below grade that resist pull-out or uplift are categorized as tieback anchors, rock anchors, soil anchors, or soil nails. These geotechnical anchors work in combination with larger design systems to achieve the desired result. They can be designed to prevent shoring or retaining wall bending/ overturning, hold down large structural foundations, stabilize slopes, and as rockfall prevention. 

The common method of installation is via cased hole drilling and the subsequent grouting of a steel bar within the section of the anchor. Upon completion of grouting, the casing is removed and the anchor is load tested after curing. Earthcore has installed thousands of anchors in many different applications and design loads. The steel bar can be specified as temporary or permanent, with many different combinations of bar strength and corrosion protection available.

Many projects require extensive testing to confirm design assumptions. The schedule is adversely affected when anchors fail load testing and must be re-grouted or reinstalled. Earthcore has perfected many different methods of installation and has an extremely high success rate in production and success rate on load testing of installed anchors.
