Installation Guide

INSTALLATION INSTRUCTIONS
At wall location, dig shallow trench for
wall base (see Typical Wall Section). Place
granular leveling pad material. Compact
and level the base pad. Place and level
the first course units. If grade changes
along base of wall, create stepped
leveling pad as required. Always start wall
at lowest elevation, working to highest.
Complete base course before proceeding
with additional courses.
Backfill first course units with clean
granular fill material (i.e. crushed
stone/gravel). DO NOT USE PEA
GRAVEL! Compact with hand tamper
or appropriate mechanical compactor.
Backfill and compact behind each course
before installing additional courses.
Starting at straight wall area, place units
centered over joint of units below to form
a running bond pattern. Build through
curves in similar manner.
Capping: If using a cored unit, complete
your wall with the appropriate cap* unit.
Use exterior grade construction adhesive
on the top surface of the last course
before applying cap units. Backfill and
compact to finish grade.
LANDSCAPE WALL | 6-IN X 16-IN WALL BLOCK
Use clean granular backfill such as gravel or crushed stone for drainage and to
prevent soil from leaching through the wall. A commercial filter fabric (stocked by
most garden supply stores) may be used when existing site soils are used for backfill.
Curves as small as 3' in radius can
be built with 6-in x 16-in Wall Block.
Convex & concave course
bonding will adjust sideways. If
stack bond occurs, remove rear
interlock lip as shown or cut
units accordingly to get back to
running bond.
Building Curves
Typical Wall Section Remove Edges
To remove outside lugs or edges of retaining lip,
hold unit securely or place at angle on ground.
Strike the lug firmly with a hammer. Always wear
safety glasses to protect eyes from chips.
