RETAINING WALL
PATTERN OPTIONS
Catalina Retaining Wall Block, with its rear lip and split-face front,
is an attractive solution for retaining walls, tiered walls, tree rings,
and raised bed projects. Walls over 3’ tall require grid.
The wedge shaped backs of
Front of Block
the Retaining Wall Blocks,
when placed side by side,
create a space (highlighted
in yellow) which securely
holds the lip (highlighted
in red) of the block above.
Back of Block
For a natural look, simply follow no pattern. With random
placement, make sure to minimize the number of matching joints
to maintain a strong wall.

FREESTANDING WALL
Catalina Freestanding Wall Block has two split sides allowing it
to be used in freestanding walls. Freestanding walls are excellent
for sitting walls, patio barriers, or fencing. See the formula to
calculate the material needed for your freestanding wall project.
A 20 inch height is ideal for most sitting wall projects. Please note
that freestanding walls should not exceed 3’ in height.

2. Level Base Course Place the first layer of block on the
prepared foundation. Use a carpenter's level in all directions
and use a string line to verify straightness. Be certain the base
course is level and the blocks lay flat. Have a rubber mallet
handy for leveling blocks. Small handfuls of sand may also be
used for leveling.
3. Stack & Fill Backfill the wall with Multi-Purpose Gravel that
will let water drain through to the drain tile behind your wall.
For maximum wall strength and durability, use a landscape
adhesive on each course. If desired, use a standard retaining
wall cap to top the wall.
NOTE: Walls over 3' in height may require geo-grid and our
professional design service. For projects over 3', please fill out a
design service quote request.

1. Prepare Base Trench Calculate the depth of your base trench.
The base trench should be 4-6 inches deep to accommodate
Paver Base material with an additional inch per foot of wall
height. Sample 2' wall height: 2" + 4-6" base material = 6-8"
trench depth. When building on unlevel areas, prepare step
downs in increments of 5". Compact and level your Paver Base.
FREESTANDING &
RETAINING WALL
Customize your wall using varied percentages of each size block.
For a wall featuring larger block use a combination like 70% 15"
block and 30% 10" block in the formulas provided on this page.
The total must equal 100%. For example, if you want to work with
only one size block, use 100% of that size in the formula.
