The 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.
