In a soil nail application, the Soil Screw Retention Wall System constructs a gravity wall to reinforce the in-situ soil with screw anchors nearly horiziontal. Anchor sizes and grid spacing are determined by soil conditions and load requirements.

A reinforced-shotcrete veneer often is applied to the face.

Screw anchors can help prevent wall movement by holding the wall when soil swells and the resulting pressure pushes against the wall.

Retaining walls can be designed using screw anchors with a modest increase in cost. Proven and building code accepted, these anchors will keep retaining walls from moving.

Basement walls can be repaired using helical screw anchors. This is accomplished by drilling a small hole for the anchor rod to pass through the basement wall, and then excavating a hole outside to place the bearing plate. A small high torque motor then rotates the screw anchor system into the soil. Once depth and predetermined torque is achieved, the anchor is terminated and a plate is mounted inside the basement wall to hold the wall in place. If the wall needs to be moved, then sufficient soil must be removed to allow the wall to move.

The CHANCE Screw Anchor saves time, money and is a proven answer to wall retention.
