Simple ProcedureThe CHANCE® SOIL SCREW™ Retention Wall System reinforces the earth to construct gravity walls.In this "soil nail" application, a Chance screw anchor acts in a bearing mode compared to grouted anchor, which relies on friction. This gives the SOIL SCREW Retention Wall System economic advantages. Bearing plates are spaced along the entire length of SOIL SCREW anchors. They are ready for immediate loading as soon as installed. Backhoes and skid-steer loaders can quickly rotate SOIL SCREW anchors into place. Anchor size and grid spacing are designed to local soil conditions and load requirements. A reinforced-shotcrete veneer often is applied to the wall face. |
 Compatible with other materials and practices.

 Predictable results - Capacity is proportional to installation torqueHelical bearing plates are spaced along the entire length of screw anchors. These true-spiral helices install with ease and minimal soil disturbance. Monitoring torque during installation accurately indicates expected holding capacity.  Technical support and pre-engineered system for design flexibility and standards compliance.The SOIL SCREW™ Retention Wall System is based on more than 80 years of earth-anchor research and development by ISO-certified manufacturer A. B. Chance Company, which also markets to electric utilities, telecommunications and pipeline industries worldwide.
