Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the gd-system-plugin domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

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.
