Step 1: Site Preparation
Begin by digging a shallow
trench 6” Deep by 12” wide. Add
2” of crushed stone and compact
to create a level base. Use sand as
needed to aid in leveling (No more
than 1” of sand should be used).
Step 2: Base Course Install
Start at the lowest point of the wall
and place the first unit of Insignia
Wall (Chamfer up as shown),
leveling it front to back and side to
side. Level each additional unit on
the base course independently and
with the adjacent units.
Step 3: Pin Placement
Each Insignia Wall unit requires two
Keystone Pins. Pins should fit easily
into pin holes and align parallel
with the front and back of the unit.
Step 4: Backfill
Backfill behind the completed
course and after the installation
of each additional course with
crushed stone aggregate. Optional:
Fill the unit channels with crushed
stone aggregate.
Step 5: Adding Courses
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 back until the
pins contact the outside edge of
the channel.
Step 6: Capping the Wall
Finish the wall with Insignia Cap
for a polished look. Depending
on the design of the wall, cutting
of the cap units may be necessary.
Secure the cap units with concrete
adhesive.

TECHNICAL TIP: Create half units as needed by scoring and splitting the stones with a masonry chisel
and small sledge hammer, or cut using a circular saw with a masonry blade.
