			'''Description.''' Mechanically stabilized earth wall systems consist of a reinforced soil mass placed behind facing units. Types of MSE wall systems include drycast modular block wall (DMBW-MSE), wetcast modular block wall (WMBW-MSE) and precast modular panel wall (PMPW-MSE). Information concerning the types, appropriate uses and design of MSE walls can be found in [[751.24 LFD Retaining Walls#751.24.2 Mechanically Stabilized Earth (MSE) Walls\|EPG 751.24.2 Mechanically Stabilized Earth (MSE) Walls]]. Contractors are responsible for performing the design of MSE walls. Only the wall systems shown in the [https://www.modot.org/bridge-pre-qualified-products-list Bridge Pre-qualified Products listing] will be available for use by the contractor.

	'''When NOT to Use MSE Walls.''' You must have adequate room behind the wall for the reinforcing straps (need horizontal clearance behind the wall of approximately 0.7 times the height or more if seismic loading is considered). You also can NOT use MSE walls in locations where the underlying soil cannot support the weight of the fill and the wall (rare occurrence). This is determined by the District Geologist/Geotechnical Director.		'''When NOT to Use MSE Walls.'''
