Installation Instructions

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. Behind the Clifton or Denver Units, the geogrid will overlap because of the convex curve. In these
areas place 3" of fill material to separate. Never compact directly on the geogrid.
Step 2 - Successive Grid Layers
Repeat Step 1 when installing additional layers of grid. Fill cores and the drainage zone with aggregate
material on every course. 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 compactors
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.
