A Mechanically Stabilized Earth (MSE) retaining wall is a composite structure consisting of alternating layers of compacted backfill and soil reinforcement elementsDirt is probably the cheapest and simplest construction material out there, but it’s not very strong compared to other choices.

Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort – Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you’ll see MSE walls are everywhere.
The main advantages of MSE walls compared to conventional reinforced concrete walls are their ease of installation and quick construction.
They do not require formwork or curing and each layer is structurally sound as it is laid, reducing the need for support, scaffolding or cranes. They also do not require additional work on the facing.MSE walls stabilize unstable slopes and retain the soil on steep slopes and under crest loads.
