Perforoc is specialized in developing cost-effective foundation solutions that meet the needs of our clients. Specialized in drilling and installing rock anchors, Perforoc also provides services for drilling and installing micropiles and strands.

Anchors are used to allow prestressing on a structure by holding a tension load in the anchor or strand. Those high-grade steel elements are then permanently bonded to the structure through the injection of a cementitious grout. Tensioning will help reduce structural movements.

Anchors are installed down to a maximum of approximately 50m through overburden and roc to hold loads of over 200tons. Whether you want to use conventional anchors (Dywidag, Skyline, Williams), tiebacks, hollow core bar systems, rock bolts with shell or soil nails, Perforoc can satisfy your needs in foundation solutions.

Furthermore, Perforoc can perform the necessary proof, performance, lift-off and permeability tests on his anchors.
