It makes the difference, the Keystone Landscape Pin.
Why Pins?
Pins matter because you care about…
Performance
Keystone interlocking pin system adds strength and structural integrity to a retaining wall far superior to that of a rear lip system. Keystone
interlocking pins are designed to provide the best wall performance – they ensure the wall unit is installed in alignment and maintains alignment
and stability for years to come.
Installation
Allowing for secure installation with ease, Keystone interlocking pins take the question out of proper block placement, reducing time
and improving your installation experience. Keystone pins easily slide into the pin channels of Keystone 2-PC Country Manor® and the
front cores of the Insignia™ wall units; securing them in place. (See product specific installation instructions for additional details.)
No Maintenance
Keystone interlocking pins are weatherproof, allowing the wall to withstand the freeze-thaw process, and other weather challenges.
Savings
Using Keystone interlocking pins saves you time and money. Keystone pins reduce the cost of concrete adhesive and simplify the
installation process. Projects using Keystone pins require little, to no, repair over their lifetime.
Try the Keystone interlocking pin system with your next Keystone wall project
and see what a big difference these little pins can make.

installation instructions
Step 1: Site Preparation
Step 2: Base Course Install
Step 3: Pin Placement
Step 4: Backfill
Step 1: Site Preparation
Begin by digging a shallow
trench 12” Deep by 20” wide. Add
4-6” 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).
Start at the lowest point of the
wall and place the first unit of
Country Manor, leveling it front
to back and side to side. Level
each additional unit on the base
course independently and with the
adjacent units.
Insert Keystone interlocking pins
into the desired pin holes in the
outside holes of the block for either
a 1” positive or negative setback,
or in the middle pin hole for a
vertical wall.
For retaining walls use a 1/2”-3/4”
clean crushed stone 12” deep
behind the wall to backfill. Fill open
spaces between blocks and inside
open cores after the installation of
each course.
Step 5: Adding Courses
Step 6: Capping the Wall
Stagger the bond from the
previous course as shown. Pins
from the lower course will secure
into the pin receiving channel
in the bottom of the unit being
installed.
Finish the wall with a Country
Manor 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.
