Evaluation of the Keysystem(TM) I Retaining Wall

The report describes a HITEC evaluation designed to determine the basic capabilities and limitations of Keysystem I for use as a technically-viable precast MSE retaining wall system. The evaluation was conducted based on design, construction, performance, and quality assurance information outlined in the HITEC Protocol. Keysystem I features modular block facing (MBW) to which KeyStrips are attached. Keystrips are structural welded-wire, grid-type reinforcement produced from high-strength steel.
