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.
