TechWall™ is a precast counterfort retaining wall system which combines counterfort design advantages with thequalityandefficiencyofprecastconcrete.Keytotheoverallefficiencyofthesystemisthesuperiorityofcounterforts, 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.

CONSTRUCTION SEQUENCE:• Precast panels are set, each with its two vertical legs resting on a
leveling pad or shear key
• Lateral bracing is installed
• Footing forms are erected
• Reinforcing steel is placed and tied
• Footing concrete is poured
• Structureisbackfilled
TechWall is used when space or design constraints favor a cantilever type wall. Types of constraints include limited right-of-way, roadway widening, large utility zones, construction in cut conditions, soundwall freeboards and more.
