Soil Screws & Tiebacks

SOIL SCREW® Retention Wall System uses screw anchors as bearing devices as compared to grouted anchors which rely on friction. To construct a gravity wall to reinforce the soil, SOIL SCREW® anchors have bearing plates spaced along their entire lengths. Anchor size and grid spacing are designed to local soil conditions and load requirements. A shotcrete-reinforced veneer may be added to wall face. Each SOIL SCREW® anchor is rated for 70,000 lb. minimum ultimate strength.

Chance™ screw anchors for tiebacks come with shaft sizes and single-or multi- helix plate diameters selected for job-specific requirements. Tiebacks are typically used for excavation retention bulkheads, retaining walls and roadway abatements. Chance™ tieback anchors are rated for 70,000 lb. to 200,000 lb. minimum ultimate strength.
