Depending on the size of your wall, you may
need a permit if you are in the city limits, check with your
local building officials. |

Determine where your wall is going to be
installed, using a hose or string laid out on the ground to
get a visual idea what shape you want. If you are building an
actual retaining wall, you will want to bury at least half of
the first layer of stone. This will provide stability to your
walls, and make them less susceptible to moving. Dig a trench
wide enough to accommodate the width of the stone you are
planning on using, and deep enough to allow for about 6-7” of
base material and half the height of the stone. |

Install a base material of crushed Limestone or a
class 5 gravel approx 6” thick, and tamp it. Then install about an
inch of sand on top, which will be used for leveling each stone.
Place each stone in a row, tamping the stones into place with a dead
blow hammer. After your first row of stone is in place, you should
install a drain tile behind your wall. This will allow any water
that get behind your wall to drain out. Water behind a wall is one
of the most common reasons for a failed wall. Cover the draintile
with a washed crushed rock for back fill. After each row of stone is
installed, back fill using the crushed rock, and tamping it every
layer, or every other layer. Cover the last 6-8” of backfill with
topsoil. This will allow rainwater to run over your wall, instead
of behind it. |
