What are mechanically stabilized earth walls?
What are mechanically stabilized earth walls?
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.
How is mechanically stabilized earth constructed?
An MSE wall employs facing elements, soil, and reinforcement that work together to form a gravity-retaining structure (Figure 1). Compacted soil backfill is interlayered with soil reinforcement, together forming a reinforced-soil mass. Reinforcement penetrations from various civil site improvements.
How is soil reinforced in mechanically stabilized earth?
In a typical MSE wall, compacted granular soil is reinforced by horizontal layers of steel strips or geosynthetic materials. The use of reinforced elements significantly increases the strength of the system.
What are reinforced soil slopes?
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. For a stone faced structure, we provide a Biaxial geogrid face wrap with extra carbon black for UV protection.
How strong is rammed earth?
The compressive strength of rammed earth is dictated by factors such as soil type, particle size distribution, amount of compaction, moisture content of the mix and type/amount of stabiliser used. Well-produced cement-stabilised rammed earth walls can be anywhere between 5 to 20 MPa.
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 MSC wall?
MSC is a composite wall panel system combining regular hardrock concrete, approximately two inches thick on the exterior, and standard light-gauge steel framing on the inside.
How much does an MSE wall cost?
Typically MSE walls materials only are about $12 to $13 per square foot. This is for the panels and hardware. You must include the installation of the MSE materials, furnish and installing the backfill behind the MSE. There are different types of backfill ranging from aggregate to lightweight foam concrete.

How do you stabilize steep slopes?
There are several options now available for steep slope stabilization consisting of Coir matting, TRMs, soil nailing, concrete, and Geoweb systems. These techniques are utilized on near-vertical faces. Concrete slope protection is the only one of these techniques that will not allow for vegetation to grow on the slope.
Why is rammed earth so expensive?
Plaster was a common finish treatment. Over the past few decades, rammed earth has grown in popularity, with an increasing number of professional builders developing the requisite skills. Contrary to the law of supply and demand, however, in which competition reduces prices, rammed earth has become more expensive.
