Step 1
- Base Course Preparation
Beginning at a point of the wall’s
lowest elevation, excavate a trench
down the length of the wall that
will accommodate at least 6" of
compacted base material. We
suggest burying 10% of your wall
height below grade with a minimum
of 6" even on short walls. Step the
trench up or down with respect to
adjacent grade. The width of the
trench for both the Denver and
Clifton Walls should be a minimum of
24". Based on the type of application
and what is retained, the depth of the
leveling pad may vary. If necessary,
consult with an engineer. After
excavating the native soil and prior to
adding base material, remove loose
material from the trench
and compact.
Step 1 (Option 2)
- Pouring a Concrete Footing
Complete all steps described in Step
1. Then, a concrete footing should be
poured on top of the granular base
course. This step will require concrete
forms set in place to create the size
footing needed.
Step 1 (Option 1)
- Using an Edger
Add a concrete edger in front of
the retaining wall to act as a bolster
against grass and weeds. Retaining
wall must sit a minimum of 6" below
grade. Top of edger should match
top of grade.
