ECONOMICAL ENGINEERED CONCRETE RETAINING WALL SAVES UP TO 30%

A new system for engineered concrete retaining walls could save as much as 25 to 30% compared to costs for conventional engineered retaining walls, according to projections by American Geo-Tech, Inc. The wall employes a tendon tie-back system. It does not depend on friction, and therefore can be used with on-site fill. Face panels measure 8 ft X 5 ft, 4 in. and weight 3,200 lbs, with custom sizes possible for special applications. They are typically precast. The tendon tie-back system joins panels together using A-36 steel tie rods with a fusion bonded A-775-81 epoxy coating for effective corrosion protection. The bolted connections are isolated from the soil environment. Horizontal and vertical joints are sealed with nonwoven polyester cushion materials.
