Retaining and Keystone Walls
Performed by excavating a new trench 8”-12” in depth. Removing
excess fill material from the site. Compact new base material
using a vibratory plate compactor. Then we shall install geogrid
mesh every 2-3 courses depending upon requirements set forth.
All compaction shall be done in 2 to 4 inch lifts. Place stone
units side by side set level in all directions. Back fill wall
with clean granular fill or gravel as agreed upon. A
filter fabric shall be installed between fill and wall stone
to prevent wash through. Add
wall cap as desired and agreed upon.
