A MSE Segmental Retaining Wall provides a flexible and appealing system that is easy on the pocket. Site plans that require a retaining wall for grade separation using a fill condition benefit from the MSE Segmental Retaining Wall system that is made up of concrete facing units connected to soil reinforcement composed of materials resilient to physical deterioration.
MSE Segmental Retaining Walls are quickly installed using the backfill product that can be placed and compacted behind the wall. If you are concerned about weather, Stone backfill can be used in place of soil during installation process. Segmental Retaining Walls are typically 20% to 40% more cost-efficient than conventional Cast-In-Place for walls over 10 feet high. Facing units can be radius or straight faced and are available in a variety of textures and colors.
The MSE Panel retaining wall system consists of a precast concrete fascia panel and reinforcing steel that is tied to the back of the fascia and extends horizontally into preselected and compacted earth backfill. The MSE Panel Retaining Wall system performs especially well in a variety of conditions, and exceptionally well in seismic zones because of the built-in flexibility of the system. The built-in flexibility allows for certain movement without causing distress to the structure or producing cracks. MSE Panel Retaining Walls can also tolerate a specific amount of settlement that makes it a desirable solution even in relatively poor subsoil conditions.
The primary interaction among the facing panels, reinforcing steel and the selected backfill forms a block-like structure that is a good support for elevated roads or similar construction. The precast fascia is available to be manufactured with many different textures and colors.
Not unlike segmental block retaining walls, MSE Rock Filled Wire Face retaining wall systems are ideal when your site requires a retaining wall for grade separation. For support, welded wire basket forms are used instead of the concrete facing units. The baskets are wrapped in a biaxial geogrid reinforcement that holds the crushed rock in place. The uniaxial geogrid product is used to reinforce the retaining wall structural backfill. MSE Rock Filled Wire Face retaining walls are a quickly installed because the crushed rock backfill can be placed and compacted behind the wall. Baskets come in a variety of materials and can be made of galvanized steel for applications near water that need to withstand and resist hydraulic forces of streams or rivers.
Similar to Segmental Block and Rock Filled MSE retaining walls, MSE Vegetated Retaining Wall systems will also work when your site requires a retaining wall for grade separation. Welded wire basket forms are used instead of the discrete concrete facing units. The baskets are wrapped in a polymeric geogrid reinforcement and are filled with soil. They can be planted with foliage or hydroseeded with grass providing a “green” alternative to conventional retaining walls. The retaining wall virtually disappears over time as the vegetation growth expands to hide the structure’s baskets.
For over 40 years, MSE Berms have been used in roadway applications. They have been used in landfill applications for approximately 20 years. As existing landfills are nearing capacity,significant utilization of MSE Berms has increased and finding new sites for landfills is very difficult. Owners and environmental agencies are now actively exploring ways to optimize the capacity of existing landfill footprints. Constructing a properly engineered perimeter berms around a landfill facility is one great option.
Another optimization technology is the use of mechanically stabilized earth (MSE) berms. MSE Berms consist of compacted earth that are reinforced with geosynthetic layers. MSE Berms provide extremely more disposal capacity on the existing footprint of a landfill by building a vertical structure (the MSE Berm) around the base of the landfill (or partly around the landfill), and using that space between the berm and the existing sides to fill with waste. MSE Berms may also create more capacity by increasing the height of the landfill.
MSE Berms can also used for vertical expansion of existing containment pods.
In a challenging terrain such as a steep terrain, excavation is required to establish suitable conditions for the construction of the MSE wall. Some sites do not allow for the installation of soil reinforcement for MSE Walls. In these cases, permanent or temporary shoring is often used to stabilize the backslope in mountainous, rugged, or steep terrains. Once the excavation has been shored, the construction of the MSE wall will be able to be completed.
Pressure Relief Retaining Walls can provide a faster, more cost-concious solution for addressing the critical construction need of large cast-in-place foundations that can support soil and building loads for below-grade construction, The system effectively reinforces surrounding fill, lateral soil loads against the below-grade structure and are eliminated. This allows for lower cost foundation walls that are structurally equivalent to conventional methods. Using low cost materials and speedy construction make pressure relief applications the system of choice when replacing counterfort walls or to reduce concrete reinforcement in structural foundation walls. An ideal alternative, the pressure relief retaining wall system is the ideal alternative to complete demolition and replacement of an existing structure to accommodate increased loads due to facility expansion.
