Rock anchoring is typically adopted where more significant restraining forces are required to stabilise large rock masses or structures, and where the failure of an anchor is considered unacceptable.
Permanent rock anchoring demands double corrosion protection and a stringent acceptance testing regime prior to imparting the design load into each tendon.
CAN installs both monobar and multi-strand rock anchors, whilst our plant and equipment has been developed to enable this work to be carried out in almost any location. In badly voided ground, measures such as grout sock and polymer modified grouts are used to limit grout losses. Portable pneumatic/hydraulic power packs allow CAN to carry out cyclic testing efficiently on large cliffs.
