Brick Paving Process
The concrete paving stones are purchased at the Paveloc Industries, Inc. factory in Marengo, Illinois. Nearly half of the pavers are hand sculpted to fit the intricate design before they are shipped to the installation site.
The concrete containment ring is constructed at the installation site. First, the entire area for the labyrinth is excavated 15 inches deep from finished grade. Then the containment ring is poured, using some steel rebar to provide extra support. The containment ring should be 4 to 6 inches wide and 12 to 15 inches deep. (If cost reduction is a major concern, we recommend using a local contractor and volunteers for this part of the process.)
Approximately 50 percent of the paving stones are hand sculpted for a labyrinth installation. Pencil lines are drawn on the pavers to mark the precision cuts for the intricate design.
Marty and his crew travel an average of 1,000 miles to each installation site and spend approximately 180 days of the year on the road.
The crew and the paving stones are scheduled to arrive at the installation site about the same time. LIS purchases base material from a local supplier to fill the containment ring. A quality foundation consists of 10 to 12 inches of base material, which is compacted in 4-
The complex process of labyrinth installation begins in earnest. Marty determines the placement of the labyrinth components (e.g., quadrants, entrance, lunations, trefoils). The concrete paving stones are then laid out in the design.
Sand is swept into the joints, and the process of compaction is completed. Compaction locks the pavers permanently into place, ensuring the durability of the labyrinth for generations to come. The surface is then thoroughly swept and cleaned, revealing the labyrinth’s stunning artistry.
What kind of color fading do the pavers experience?
Under normal conditions, concrete paving stones fade very little. They are even more resistant to color fading when coated with a high-
What kind of maintenance is required?
That is the beauty: there really is none! Depending on the foot traffic, a thorough once-
Can you use a shovel to remove snow without harming the pavers?
Yes, you can. In fact, a shovel will glide effortlessly across the labyrinth as if it were a wooden gym floor without snagging a single brick. The only time we have seen any damage from winter cleaning was when someone repeatedly stabbed at the ice with what appeared to be the corner of a shovel or a steel bar. No paved surface that we know of could have held up to that kind of abuse. For virtually effortless and safe ice removal, you might want to consider using a salt-
Do you use concrete or brick pavers?
We can use natural stone, clay pavers, or concrete paving stones. Natural stone is very beautiful, but it is also the most expensive. Clay pavers come in beautiful colors, but the pavers themselves are somewhat fragile. Most of our labyrinths to date have utilized concrete paving stones manufactured by Paveloc Industries. They are the most cost-
What about sealing vs. not sealing?
As noted below, pavers come with a lifetime guarantee from the factory. We suggest applying a thorough coat of high-
What material is used underneath the pavers?
We have learned over the years as we travel across the country that it is necessary to be flexible and use whatever granular material is used in the region for highway construction. (A reputable supplier’s phone number always comes in handy during this part of the process.) In Chicagoland, for example, we use crushed limestone.
