Once you have completed the footing hole, fill it with crushed stone and compact it with the backhoe or a plate compactor. This will ensure a stable footing base to support the retaining wall.

Using concrete landscaping blocks, place a row of them along the top of the footing. Use a level or a string to ensure they are level along the entire length of the retaining wall.

Apply a second row of concrete landscaping blocks, making sure to stagger them relative to the lower row. Stagger them such that the middle of the upper block sits above the seam of the two lower blocks.
