Rock Anchors

Mat Footing Uplift

When highly loaded structures bear on shallow rock, a mat foundation is often used. These mat foundations also sometimes carry uplift requirements. Grouted anchors drilled from the bearing surface into the rock and cast integral with the mat is an efficient solution to this problem.

Drilled Pier Uplift

Design of drilled piers sometime requires rock anchors extending below the pier tip into bedrock for uplift capacity. This can be accomplished either during construction or after construction of the drilled pier as a retrofit. These anchors are grouted with reinforcing steel. Grout to rock bond provides the required uplift capacity.
