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.
