Installation Guide

INSTALLATION INSTRUCTIONS
Begin by digging a shallow
trench 6"(152mm) deep
by 15"(381mm) wide. Add
2"(51mm) of crushed stone
and compact to create a
level base. Use sand (do not
exceed 1"[25mm]) as needed
to aid in leveling.
Backfill behind the completed
course, and each additional
course, with granular free
draining soil.
Optional: Fill unit
open cores with free draining
crushed stone aggregate.
Start at the lowest point of the
wall and place the first Insignia
wall unit (front face chamfer
up as shown), leveling unit
front to back and side to side
both independently
and with the adjacent units.
Stagger the bond from the
previous course as shown. Pins
from the lower course will
secure into the front pin
receiving channel in the
bottom of the unit being
installed. Push the wall unit
forward until the pins contact
the back edge of the
front open core.
Each Insignia wall unit
requires two Keystone
alignment pins. Pins should
fit easily into pin holes
Note: Install pins before
adding soil or stone fill.
Finish the wall with Insignia
cap for a professional look.
Depending on the design of
the wall, cutting of the cap
units may be necessary.
Secure the cap units with
exterior grade concrete
adhesive.
