Step by Step: How to build a retaining wall
- Dig a level-bottomed trench wide enough for the base stones to fit into. Compact the bottom of the trench with a hand tamper.
- Lay landscape fabric in the trench.
- Start the wall’s second layer using a staggered pattern.
- Make sure the wall is level.
Can I build a retaining wall myself?
While retaining walls taller than four feet should be engineered by professionals, you may be able to DIY a solution for a tall slope by creating two or more shorter “tiered” retaining walls as opposed to a single tall wall.
How deep should the footing be for a retaining wall?
Concrete retaining wall footing size
The depth to the bottom of the base slab should be kept at a minimum of two feet. However, it should always be below the seasonal frost line, and that often is much deeper in northern climates.

Rules of thumb commonly used by designers to establish the geometry of the wall include (refer to diagram): Base width = 1/2 to 1/3 of the height of the wall. Base thickness = 1/8 of the height of the wall but not less than 12 inches. Stem thickness = 6 inches + ¼ inch for each foot of wall height.
