Retaining walls often times fail due to shifting & moving soils. Dwyer’s pre-engineered round-shaft anchors provide tremendous tension & lateral support, and our anchors can be grouted for even greater support. Once the helical anchors are installed to the proper length, threaded bars and plate steel caps are used to secure the anchor to the wall. The wall and the tieback are tensioned to one another to stabilize and/or straighten the wall. Additional tension can be applied to the tiebacks in the future should shifting occur.
