Installation Instructions

CLIFTON STRAIGHT
Step 1 - Grid Placement
Cut geogrid to required lengths and place the grid as close to the face of the wall without exposing it
when following the contour of the curve. Place the next course of SRW block, taking care that the grid sits
flat and is secured between the units. Each geogrid length should be laid perpendicular to the wall face
and pulled tight to remove any slack. The geogrid should never overlap on top of the Clifton or Denver
Units.
Step 2 - Successive Grid Layers
After the next course of block is placed, lay the grid to cover the area of non-reinforced soil below. This
will ensure 100% coverage. Place the next layer of infill soil on top of the geogrid by beginning near the
wall fascia and spreading it back across the grid. Backfill in 3"-6" lifts, using only vibratory plate compac-
tors within a 3' area from the back of the wall. Place soil in the rest of the infill area in maximum lifts of 6"
based on the rating of your compaction equipment and compact to obtain a 95% Standard Proctor densi-
ty. Repeat these steps for successive specified grid layers.
