Cantilever walls are built of reinforced concrete and are typically composed of a horizontal footing and a vertical stem wall. The weight of the soil mass above the heel helps keep wall stable. Cantilever walls are economical for heights up to 10 m (32 feet). Typical costs in 2005 is approximately 80/sf.
Mechanically Stabilized Earth (MSE) Walls MSE walls offer the most flexible, aesthetic and economical wall system when retaining walls are required in a fill condition or if there is enough lay back to make a cut approximately equal to the wall height. MSE walls consist of a well compacted granular backfill that can be reinforced with ribbed steel strips, geogrid or geosynthetic strip reinforcement.
• The MSE wall design engineer assumed soil strength parameters on the basis of local knowledge or on ideal values for imported fill that were provided by the MSE wall installers, rather than on sitespecific values provided in a geotechnical engineering report. (In some cases, the design engineer had not

MoDOT Internet site contains a listing of facing unit manufacturers, soil reinforcement suppliers, and wall system suppliers which have been approved for .
Call Today (352) . MSE is soil constructed with artificial reinforcing. It can be used for retaining walls, bridge abutments, seawalls, and dikes. Also, ideal for backfilling walls road design and construction, bridge construction, railroad construction and marine construction for retaining walls, bridge abutments, seawalls, and more.
MSE Walls Slopes Products EnviroGrid cellular confinement system (geocell) The EnviroGrid cellular confinement system (geocell) is produced from High Density Polyethylene (HDPE) and has three dimensional cells that contain, confine and reinforce a variety of fill materials including native fill, topsoil, granular or concrete.
Approach retaining walls are commonly needed in urban areas due to the lack of available rightofway for side slopes. The most common fill walls in this situation are mechanically stabilized earth (MSE) or concrete block. 2. Slopes. Fill walls placed on slopes require special consideration.
