Ground Anchorages are used to resist tension forces and can be installed for a variety of applications. They are typically used for slope stability, as tie-backs in retaining structures, or to resist uplift forces in structures.
Anchorages can be either passive or active in type and are used in both temporary and permanent situations.
They are formed using a variety of drilling and auguring techniques depending on their application and the ground conditions.
With solid bar and strand anchors, when the bore has been advanced to its predetermined design length, anchor tendon is inserted and the pile bore is filled with grout.
Depending on the application of these elements, a detailed stressing and testing regime may be necessary after the grout has cured. As anchors are required to be installed at a variety of angles, heights and on sloping surfaces, the specialist equipment used to install these elements has to be versatile to suit the environment.
