A retaining wall is generally used to create level surfaces. This is especially useful as level land is increasingly harder to come by in established communities. All remaining undeveloped parcels usually contain steep slopes or development has come up against hilly or mountainous terrain at the outskirts of towns.
Other more specific reasons include:
Homeowners attempting to create a level space for a patio or backyard that is currently too steep require a retaining wall.
Cities, Counties and State DOT widening road or constructing highway interchanges.
A developer needs a level surface for a parking lot and/or building pad.
Private mining companies creating a truck dump pad for a crusher.
There are generally 2 types of walls, cut and fill walls. There are a multiple kinds of retaining walls including gravity, embedded walls, and tie-back walls. MSE walls are tie back walls and generally easier to construct as fill walls. Cut (cutting into the existing ground) walls require excavation for soil reinforcement. Due to the possible high cost of excavation or property line limitations a different kind of wall may need to be considered in a cut wall situation.
