masonry edging

Common Options

Concrete A formed concrete edging is the best retainer of patio materials. Dig a 6-inch-deep trench, tamp, add 2 to 3 inches of gravel, build forms, and pour concrete.

Upright bricks or pavers Bricks or pavers should rest on a concrete footing. Set them in wet concrete or set them in mortar after the concrete cures.

Tilted soldiers To set a tilted edging of bricks or pavers dig a trench 8 inches deep, tamp, add 2 to 3 inches of sand, and set the bricks. Backfill firmly.

Flagstone edging Flagstones simply can be set in well-tamped ground. Make adjustments as you go, digging or adding soil to make the top edges of the stones fairly even.

Other edging materials

Landscaping timbers or railroad ties This edging is quick to construct and strong. Dig a trench, tamp, and add 2 inches of sand. Place the timber, drill holes, and drive in spikes or rebar.

Upright logs Cut the logs with a chainsaw; 16- to 24-inch lengths work well. Treat the bottoms to prevent rot. Dig a trench, add gravel and sand, and install logs.

Lumber Choose pressure-treated lumber or heartwood of redwood or cedar. Set 2x4s in a shallow trench and support them with metal stakes.

Steel ribbon This works well for curves. Mark a curved line on the ground and tap the metal into the ground. Pound in retaining stakes through premade slots in the edging.

Plastic edging Plastic is cheap and easy, but seldom holds its shape and may crack. Slice a line in the ground with a shovel and push the edging into it. Reinforce with stakes.
