How is an MSE wall constructed?
A 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 result is a coherent gravity structure that is flexible and can carry a variety of heavy loads.
What are MSE walls used for?
Description. MSE walls stabilize unstable slopes and retain the soil on steep slopes and under crest loads. The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement.
What is MSE panel?
MSE (Mechanically Stabilized Earth) walls are used to stabilize slopes and retain soil. They’re generally made from precast segmental blocks, panels, or geocells that are designed to tolerate movement. The precast forms are filled with soil to create a strong structure that is able to retain the soil backfill.
What is an RSS wall?
Reinforced Soil Slopes (RSS) are compacted fill embankments that incorporate the use of horizontal placement of geosynthetic reinforcement to create a stable, oversteepened slope structure.
Who invented MSE wall?
Henri Vidal
Henri Vidal is credited with inventing modern MSE retaining wall technology. Operating as a separate entity in the United States since 1971, we are affiliated with the global group Terre Armée. French for “Reinforced Earth,” Terre Armée was established by Henri Vidal after he patented modern MSE in 1963.
What are the types of retaining wall?
Types of retaining walls
- Reinforced Retaining Wall.

- Counter-fort / Buttressed retaining wall.
- Cantilevered wall.
- Reinforced Soil Retaining Wall.
- Soil nailed wall.
- Anchored wall.
- Sheet Piled wall.
What is Flex MSE?
Flex MSE is a Patented system with a design life of over 120 years that leverages Mechanically Stabilized Earth (MSE) principles along with geotextile technology to create strong and easy to install Geomodular block structures that can be planted.
What is a gravity retaining wall?
Gravity Retaining Walls A retaining wall that relies solely on it’s own weight to stand up is called a gravity wall. Allan Block combines the basic engineering principles of setback, leverage and total unit mass with simple mechanics to make highly stable gravity walls.
What is gabion retaining wall?
A gabion wall is a retaining wall made of stacked stone-filled gabions tied together with wire. Gabion walls are usually battered (angled back towards the slope), or stepped back with the slope, rather than stacked vertically. Galvanized steel wire is most common, but PVC-coated and stainless steel wire are also used.
What is a temporary MSE wall with mesh facing?
Similar to a conventional MSE wall, but with relaxed design requirements and a shorter service life, a temporary MSE wall with wire mesh facing can be left in place or easily removed after use. Temporary MSE walls can also be incorporated into the permanent structures, allowing for extra efficiency in design of the overall project.
Why choose terratrel® wire MSE wall?
A TerraTrel® wire MSE wall is constructed in a fill location, for carrying Class I Railroad during phased bridge construction. Lightweight facing material, no heavy lifting needed. Inextensible soil reinforcements allow for predictable installation.
What are the options for temporary solutions to wire mesh walls?
For temporary walls, black steel is also an option. For temporary solutions, geotextile is placed on the back face of the wire mesh, to allow for drainage and to prevent loss of backfill.
What is the design life of a wire mesh wall?
Corrosion protection in the form of galvanization, or occasionally stainless steel, is included to achieve a design life of 75 years, 100 years, or more. For temporary walls, black steel is also an option. For temporary solutions, geotextile is placed on the back face of the wire mesh, to allow for drainage and to prevent loss of backfill.
