Pressure-treated landscape or cedar timbers make attractive, durable edging that’s easy to install. Square-edged timbers are best for geometric pavers like brick and cut stone, while loose materials and natural flagstone look best with rounded or squared timbers. Choose the size of timber depending on how bold you want the border to look.

Lumber or timber edging can be used with any patio surface material. Here, this lumber edging is not only decorative, it also holds all of the loose material in place.

How to Install Timber Edging

  1. During the site excavation, dig a perimeter trench for the timbers so they will install flush with the top of the patio or walkway surface (or just above the surface for loose material).

  2. Add the compacted gravel base, as required, including a 2" to 4" layer in the perimeter trench.

  3. Cut timbers to the desired length using a reciprocating saw with a long wood-cutting blade, a circular saw, or a handsaw.

  4. Drill 1⁄2" holes through each timber, close to the ends and every 24" in between. Cut a length of 1⁄2"-diameter (#4) rebar at 24" for each hole using a reciprocating saw and metal-cutting blade. 

  5. Set the timbers in the trench and make sure they lie flat. Use your layout strings as guides for leveling and setting the height of the timbers.

  6. Anchor the timbers with the rebar, driving the bar flush with the wood surface.
