How do you create a structural edge to contain a walking meditation space made of concrete pavers? Here are three solid options.
Recently a client asked me to recommend a containment curb or edging around the perimeter of an installed paver kit labyrinth. I wanted to clarify this for her and for other landscape architects or designers who might consider using a paver labyrinth in upcoming projects.
The perimeter of a concrete paver labyrinth can be secured in one of three standard ways:
You can use below-grade poly "brick edge," which is an L-shaped extrusion sold in 10' lengths. There are many styles and brands - buy one specifically meant for curved edges, unless you're installing and octagonal design. Brick edge is secured into the compacted base with 10 - 12" spikes - this is the structural reason why your base extends beyond the finished pavement. The surrounding material - grass, gravel, whatever - covers this edging.
Another solution that some landscaping contractors prefer is to install a mortar ring with rebar below grade and then cover.
Others use a poured concrete curbing at grade instead. If a perimeter sidewalk is part of your design, it will serve the same function as the poured concrete curbing. I suggest you pour the concrete curbing or sidewalk first and cut the final row of pavers in the labyrinth plaza to fit - we can advise you on appropriate inner diameters to fit each kit. Be sure to watch your levels so that the surrounding sidewalk doesn't impede the natural flow of water off the surface.
