This variation is a conventional and economical choice, especially when compared to that of the traditional cantilever system design. This variation increased the material efficiency of the traditional cantilever system. This allows there to be a thin wall facing between them and for a more efficient footing design. These counterforts act as the cantilever beams that resist the aforementioned lateral pressure. Instead of designing the whole length of the facing stem to resist the Earth’s lateral pressure, there are one or two counterforts on the backside. Facing units that have been precast are secured into a precast or cast-in-place footing. Precast ModularĪ precast modular retaining wall is a variation of a cantilever stem wall. Suitable design criteria are also required to assess deterioration and corrosion of materials. This means that there is no standardization for this structure. This could exponentially raise the price of construction.įinally, processes relating to these structures are still evolving. In such a case, you would need to import it to the location. Depending on the area, there may not be a lot of this available. These walls require a relatively large area behind the wall to ensure internal and external stability is achieved.Īnother consideration when speaking on MSE is the amount of granular fill needed. While there are plenty of great things about MSE, there are some drawbacks to consider. Flexibility enough to accommodate several feet of the total settlement.Rapid construction with predictable and repetitive processes.Free-draining because of granular backfill with open panel joints.Aesthetically speaking, they can be customized to be quite appealing with murals or other materials. They can be built to incredibly large wall heights and special design allows for nearly any geometry. This type of retaining wall is also very versatile. In addition to their load-bearing, they have great strength to stand up against seismic and other dynamic forces. MSE walls have the ability to accommodate extreme loads such as cranes and bridge abutment footings. Its bearing pressure is spread out over a very wide foundational area. One of the most apparent of these includes its stability and strength. There are plenty of advantages when it comes to MSE. These structures can carry heavy loads and are considered a coherent gravity structure. The stability of these types of retaining walls is derived from the friction and tension involved with the soil reinforcements and compacted backfill. Its function is mostly related to the protection of the structure and erosion. These elements are then fixed to a wall facing which is relatively thin. These are composite structures with altering layers of soil reinforcement elements and compacted backfill. MSE stands for mechanically stabilized earth. Wondering how to choose a retaining wall material? Read on to discover the advantages and disadvantages of MSE vs Precast Modular vs Segmental Block retaining walls. One of the most important considerations is the types of retaining walls. When designing and building one, there are several factors that come into play. These walls are also practical and eye-catching additions to any home or businesses’ landscaping. Retaining walls are built to contain the soil that rests behind them.
