More Photos of Kanuga Labyrinth Construction
|Left: Filling the lines with polymer concrete. On the last day, we had two extra workers to finish before the rain. We just made it.|
|Right: This close up of a lunation tooth shows the polymer concrete mix. (That's just a pencil line at the tip of the tooth, used to guide the cutting.) When viewed as a whole, the pattern seems to be inlaid deeply into the concrete, although it is really applied to the surface. Note how the shadow formed by the cut gives a dark outline to the tooth.|
|Left: Completed labyrinth. The color may look a little blotchy because it is still drying. Concrete takes several days to dry completely, and a month to reach full strength. The leaves are quite acidic, and left colored stains on the unsealed concrete, which will be permanent. The resulting appearance is fitting for the setting, as the labyrinth looks out to the woods, beyond which is Lake Kanuga.|
For those who know Kanuga, the labyrinth is located near the gymnasium. Our
thanks to Bob Haden, of the
Haden Institute, who was instrumental in presenting the idea of a labyrinth at Kanuga in a convincing way.
And to Albert Gooch, long-time director of Kanuga, who had the vision to see what a valuable addition the
labyrinth will be. For more information abut kanuga, see (www,kanuga.org).
Post script: Other than our prototype, this was our first polymer concrete
labyrinth. In the subsequent years,
we have honed our technique. In the heat of the day, when the concrete was getting very thick and hard to
manage, we added water to make it thinner. The hotter it was, the more water. This dilution may have led to
the fact that the color has faded considerably. (We did not do this on subsequent labyrinths, as we learned that
keeping the polymer concrete in an ice bath keeps it liquid and useable, at full strength.) So, in late June, 2009,
we re-colored the Kanuga labyrinth, six years after completion, at our own expense (they paid only for materials)
using a slightly different form of polymer material. Even though we don't offer a formal warranty, we stand by our
work. For routine maintenance, cleaning up the labyrinth and resealing, we charge a fee.
Here is a photo of the finished result:
