How to Edge a Brick Pathway

Excavate the ground alongside the pathway where you plan to install the edging. Measure it carefully to ensure that the width of the space corresponds with the size of the wooden blocks you want to use. For example, if your redwood or cypress blocks are 4-inches by 4-inches by 2-inches thick, you need a space of 2 1/2 inches on either side of the pathway.

Dig the edging channel to a depth of approximately 2 inches below the level of the pathway. This enables you to sink about one-third of the wood blocks diagonally into the ground. Place the excavated soil on the ground on the opposite side of the edging channel for use in shoring up the edging after installation.

Water the channel slightly, just enough to dampen the soil. Press the corner of the first wooden block into the damp soil, supporting it against the edge of the brick pathway. Once you have the angle that you want, position the additional blocks one by one, leaning each against the previous one to create a jagged-tooth pattern with the top corners.

Finish the placement of the edging blocks along one side of the path, then push the excavated soil back in behind the blocks, pressing them against the pathway. Pack the soil as tightly as possible.

Repeat the process for the other side of the pathway. Use a broom to brush any remaining loose soil from the pathway in-between the wooden blocks. Water the edges lightly and allow the soil to dry; this provides support for the bricks and sets their position over time.
