MSE WALL REINFORCEMENT

Mechanically Stabilized Earth (MSE) retaining wall is a composite structure consisting of alternating layers of compacted backfill and soil reinforcement elements, fixed to a wall facing. The stability of the wall system is derived from the interaction between the backfill and soil reinforcements, involving friction and tension. The wall facing is relatively thin, with the primary function of preventing erosion of the structural backfill. The result is a coherent gravity structure that is flexible and can carry a variety of heavy loads. Soil reinforcements are typically steel or geosynthetic, in the form of strips or ladders. All soil reinforcement options have unique characteristics for pullout and tensile capacity, corrosion, and durability. Select backfill allows for reliable construction and performance of the wall, in which the gradation, plasticity, electrochemical properties, and overall durability should be closely analyzed.
