Step 1: Planning
- Draw a sketch of the
retaining wall dimensions. This will enable our staff to
provide you with the proper amount of materials
required.
- Choose your wall block
type and size.
- Before digging,
carefully lay out and mark the area with spray paint. A
string line and stakes can be used to further mark the
area.
Step 2: Excavation
- Dig a trench. It should
be a minimum 3"- 4" deep by 12" wide. (Add a minimum 6"
width for Design Wall° installations.) Add a
minimum-leveling base of 1" of crushed stone and then
compact.
- Use a tamper and level
to ensure a properly constructed base.
Step 3: Install the First
Course
- If water pressure could
be a problem, a drainpipe should be installed along the
rear face of the trench to allow proper drainage.
- Lay the first block
level on top of the foundation. Level each stone to its
neighboring stone.
- Use a level to ensure
each piece of the first layer is level side-to-side and
front-to-back.
Step 4: Install the
Remaining Rows
- Start a second row with
˝ stone offset, placing each piece tightly together.
- If your wall is over 3'
high, plastic grid reinforcement should be installed.
- Backfill the area behind
the wall using frost-free granular material and then
compact it.
- If you will be planting
behind the top of the wall, cover the backfill with
landscape fabric before adding topsoil to the area.
Leave a flap of landscape fabric up the back of the wall
to ground level to ensure proper drainage.
- When the wall is brought
to final grade, secure the top two courses of stones,
including the cap, using butyl tape or a suitable
adhesive caulking. (Optional wall coping stones are
available).
