Piano Wall - MSE Precast Retaining Wall with Traffic Barrier - Flyer

Piano Wall is a combination precast traffic barrier and MSE retaining wall which is a coherent gravity structure engineered to resist specific loading requirements. The primary components of a Piano Wall consist of alternating layers of granular backfill, and linear metallic, high-adherence soil reinforcing strips to which a full height 10-foot-long precast composite MSE wall/traffic barrier unit is attached. Its strength and stability are derived from the frictional interaction between the granular backfill and the reinforcements, resulting in a permanent and predictable bond that creates a unique composite construction material. A mechanical connection between the facing panels and the soil reinforcing strips is achieved by way of a special tie strip embed and high strength nut/bolt/washer assembly. This connection creates a system that is technically sound and highly reliable.
