Step 1 - Grid Placement
On an outside 90° corner, it is important
that grid layers do not overlap at the
corner. Place the rst grid layer at the
correct elevation and length. Each geogrid
length should be perpendicular to the
wall face. Lay the rst 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 rst 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 specied grid layers.
Step 1 - Grid Placement
Each geogrid length should be laid
perpendicular 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 perpendicular 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 minimum of 2' past the corner. Repeat
these steps for successive specied grid
layers.
