What should the thickness of a retaining wall be?
Retaining walls can be tricky to build as they need to be strong enough to resist horizontal soil pressure where there are differing ground levels. One of the things you must get right is the thickness of the wall. It should be at least 215mm thick and bonded or made of two separate brick skins tied together.
How are dead men attached to a retaining wall?
The dead men are 2×4 struts bolted to the wall studs and anchored to a perpendicular 2×4 sleeper (see Figure A). The weight of the soil on the dead men anchors the wall against the backfill pressure. It’s important to locate the bottom of the wall below grade a few inches so the earth in front of the wall will anchor the base in place.

Can a retaining wall run up a hill?
That little stone could eventually create an unattractive hump in the top course. If the wall runs up a hill, continue each base course into the hill until the top of the second course is level with the grade, and then start your second base course at that point.
What kind of lumber to use for retaining wall?
For durability, use only pressure-treated lumber rated for ground contact. Stake out the area where you plan to build the wall. Pound a stake at one end, then drive another stake exactly 16 feet away. Run the line from one stake to the next, pulling it tight. With your shovel, dig about 2 feet back into the slope.
