MSE walls are typically more cost-effective than conventional reinforced-concrete retaining structures-in some cases by 50 percent or more. Reinforcement penetrations from various civil site improvements. The components of a mechanically stabilized earth (MSE) wall. vehicles, buildings), seismic events, and water. The MSE wall system relies on self-weight of the reinforced-soil mass to resist lateral pressures from earth, surcharges ( e.g. In most systems, reinforcement is connected to facing elements. Compacted soil backfill is interlayered with soil reinforcement, together forming a reinforced-soil mass. The growth of MSE wall construction, the wide selection of materials, and variable delivery methods can create many design and construction challenges and potential pitfalls.Īn MSE wall employs facing elements, soil, and reinforcement that work together to form a gravity-retaining structure (Figure 1). The contract delivery methods vary, often confusing the roles and responsibilities of various project team members. DiFiore, PEĪdvantages in economics, ease of construction, and an abundance of proprietary wall systems have increased the popularity of mechanically stabilized earth (MSE) walls.
