TechWall - Precast Counterfort Retaining Wall - Flyler

TechWall is a precast retaining wall system which combines a full height facing panel and counterfort into one unit. The system is designed and detailed to meet project-specific requirements. Key to the overall efficiency of the system is the superiority of counterforts, acting as equivalent cantilever beams, in resisting lateral earth pressure. While the counterforts are heavily reinforced, the moments in the facing panel are minimized and a relatively thin concrete facing panel may be used. To further enhance the system’s material efficiencies the counterforts in a TechWall panel may be specifically fabricated to approximate the shape of the bending moment diagram and are generally tapered from top to bottom of each panel.
