PARTS OF AN MSE WALL
Face Pieces– Precast Panels/Wire Facing/C.I.P. Concrete
Retains Soil Between Reinforcing Mat Layers
Connection for MSE Soil Reinforcement
Soil Reinforcing Mats – Galvanized Welded Wire Mesh
Y or H-mat (2 Wire)/W or K-Mat (3 Wire)
Y or H-mat at corner or obstructions
Backfill – Select Granular/Cement Stabilized/Coarse Aggregate
Non-Corrosive Backfill to Limit Corrosion of Soil Reinforcing Mats
Unit Weight/Friction Angle
Limits from Top of Leveling Pad to Top of Top Panel
Foundation Soils
Allowable Bearing Capacity Provided by Owner (Geotechnical Engineer)
Applied Bearing Pressure Determined by TEG - Applied < Allowable
Increasing Mesh Length (up to about 1.5xH) can Reduce Applied Bearing Pressure and Increase Sliding Resistance
Recommend Undercutting Existing Soils if Allowable Bearing Pressure cannot be met

Match up Plan and Elevation/Corner Stations/Kinks/Begin End of Wall
Wall Alignment Line (Face of Panel/Face of Coping/Face of Barrier)
Panels Finish
Wall Cross Sections – Coping/Moment Slab/Min. Mesh Length
Coping Type(C.I.P./Standard Precast/Half Connector)
Coping Height/Embedment of Panel into Coping
Backfill Limits/Requirements for Soil Mat Lengths
Design Cross Sections (Flat/Broken Backslope/Infinite Backslope)
