Retaining Walls And Keystone Walls
Performed by first excavating a new trench at 8”-12” in depth. We then remove excess fill material from the site and compact new base material using a vibratory plate compactor. When the compacting is complete we install geogrid mesh every 2-3 courses, depending upon requirements set forth. All compaction shall be done in 2 to 4 inch lifts, followed by the placement of stone units side-by-side, set level in all directions. We back fill the wall with clean granular fill or gravel, as agreed upon. A filter fabric is installed between the fill and wall stone to prevent wash through. Finally, we add a wall cap as desired and agreed upon.
