What are interlocking blocks made of?

Interlocking blocks made from cast concrete are specifically engineered for building block retaining walls. The blocks are molded so there is a downward-facing lip at the back of the block, which hooks over the previous course of blocks. This creates an automatic step-back with each course, causing the overall wall to angle backward into the hillside. Not only does this make the wall quite strong but it greatly simplifies construction since the necessary backward slope, or "batter," of the wall is set automatically by the shape of the blocks.

How deep should a trench be for a block?

Dig a trench twice as wide as the front-to-back measurement of the blocks (a 16-inch-wide trench for 8-inch-deep blocks, for example).

The bottom row of blocks is a foundation layer that will be entirely buried.
