Wall Types
MSE Retaining Wall To date MSE walls are the walls most usually  faced with LOCK+LOAD modules.  MSE Walls  may use geogrid, metal mats, or geotextile as the  soil reinforcement. Crushed rock is compacted in  the counterfort zone and drainage placed at the  rear of the soil reinforcement to insure a drained  condition within the MSE zone.  Millions of square feet of LOCK+LOAD faced MSE  walls have been built and placed into service in  the last fifteen years.
Gravity Retaining Wall  LOCK+LOAD  modules may be used as stand  alone units to build gravity walls up to a height of  four to five feet depending on wall geometry and  soil conditions. For taller gravity walls a fill zone of approximately  one third of the wall height is backfilled, a row at a  time, with “No Fines” concrete; a lean mix of  cement and 3/4” crushed rock that maintains its  permeability while providing the necessary  strength to insure a stable retaining structure.
GRS Mass Retaining Wall This type of wall is typically used in situations  where very high loading is expected and is similar  to geogrid / geotextile reinforced MSE walls  except that soil reinforcement layers are placed at more frequent intervals (8” or less) to create an  extremely strong monolithic block of reinforced fill.   Again LOCK+LOAD provides an ideal facing that is  easily integrated into the GRS mass.
Soil Nail / Anchor Wall When LOCK+LOAD is used as a fascia for soil nail  walls it is used in conjunction with approximately  4 ft. lengths of wire matt soil reinforcement  spaced at 32 ‘’ intervals and that are attached to  the wall facing mat by way of wire coils.   Using soil nail top down construction faced with   LOCK+LOAD instead of the more typical shot-  crete allows the construction of tall walls in zones  where little or or excavation is possible. 
H-Pile & Lagging Wall Many projects use H-Pile & lagging as shoring  during construction that needs to be faced at the  end of the project. LOCK+LOAD can easily be attached to the H-Pile  using a “Nelson Stud” and horizontal reinforcing  steel cast into a grade beam on top of alternate  rows of LOCK+LOAD modules as depicted in the  adjacent sketch.
