Rock Anchors

Rock Anchors

Rock anchors are generally post tensioned tendons installed and secured into the underlying rock. The anchor force is transmitted to the rock by cement grout, resin or mechanical means. They can be installed in drill holes with any inclination. The bars or strands are subsequently tensioned. This provides lateral or vertical force to resist movement of a retaining structure.

Rock anchors are often used for excavation support, or as a part of permanent retaining walls, or to resist up-lift forces on foundations, stabilization of slopes and rock walls or cuts and eccentrically loaded foundations.
