Edge Restraints are essential components for maintaining your interlocking paving stone project. Without a proper edge restraint, the project will fail. The pavers shift out of place, the joints open and interlock along the perimeter deteriorates. There are several different edge restraints including: plastic, aluminum, wood, poured concrete, brick or stone. The most common and successful edging is a restraint made of High Density Polyethylene, such as SnapEdge or Barrier Edge.
Edge restraints should be used on every side of the pavement that is not supported by a solid structure. For example, for a residential patio, an edge restraint would only be needed for the exterior edges, and not for the sides that are along the home.
Reasons to use Paving Edging:
- they prevent the interlocking stones along the outside patio perimeter from pulling away.
- they eliminate the need to cut blocks at the edge of a patio or driveway
- Strong, durable and easy to install
- they form a frame to the pavement that gives it definition and shape.
These ‘L’ shape edgers can be used for straight and curved edging. Easy to handle pieces that require no extra connectors, just install with common 8-12” landscape spikes. Snap and spike together ends to create a continuous secure connection and extra support. The molded plastic ensures the strongest edge designed for commercial, vehicular, and patio/walkway applications. Can be installed before or after the pavers have been laid. Plus, it’s open base design allows for grass growth along paver edge creating a strong yet invisible edge.
1. Snap Edge – 8’ pieces
2. Barrier Edge – 6’8” pieces
- Can be used as a paver edge restraint, as well as a to create a permanent barrier between different landscape materials
- Creates a professional edge around planting beds and gardens
- Holds landscape fabric and weed barriers firmly in place
3. Aluminum Brick Edge – 8′ pieces
Step 1: It’s crucial when installing your paver base to extend the base a minimum of 8? beyond the perimeter of the pavers. Otherwise, when you install your edging your edging spikes would be placed in soil. When the ground freezes, the expanding soil will push out your spikes causing your edging and eventually your pavers to fail.
Step 2: You can either install the edging first, and then install the sand bed and pavers up to it. Or, some installers like to lay the pavers first and install the edging last. To do this, firstly pull away the bedding sand, then using a shovel cut straight down the side of the pavers to reach the base gravel and then pull back all the sand. Place the edge restraint on the base material and push the lip under the pavers and bedding sand.
If you have curves or radiuses, snip the outer plastic piece as shown above (or simply bend the aluminum unit) to make the edging flex to match the shape of the patio and cut to your desired length.
Step 3: Install 10? metal spikes about every 8? apart. For curved lengths, space the spikes more closely together for stronger support.
Step 4: Once the pavers are laid, backfill the area around the perimeter with topsoil and cover the edge restraints. This will allow for grass to grow through and hide the edge restraint
