Installation Instructions

Step 1 - Grid Placement
On an outside 90° corner, it is important that
grid layers do not overlap at the corner. Place
the first grid layer at the correct elevation
and length. Each geogrid length should be
perpendicular to the wall face. Lay the first
geogrid corner section perpendicular to one
side of the corner. Lay the second geogrid
section perpendicular to the other side of the
corner but not overlapping the first geogrid
section.
Step 2 - Successive Grid Layers
In the corner and on the next course of
blocks, place a layer of grid perpendicular to
the previous layer of grid. Repeat these steps
for successive specified grid layers.
Step 1 - Grid Placement
Each geogrid length should be laid perpen-
dicular to the wall face. Extend the grid past
one edge of the wall by a minimum of 2'.
Along the other edge, place the grid perpen-
dicular to the corner, but don’t allow the grid
to overlap.
Step 2 - Successive Grid Layers
At the next designed grid layer, alternate the
edge on which the grid is extended a mini-
mum of 2' past the corner. Repeat these steps
for successive specified grid layers.
