When the Grass Stops Growing Out of the
Wall
Straw-Clay Building Technique Grows in Canada
By Wendy Priesnitz
It
was a cloudy June morning in north Toronto, Ontario. A couple of dozen kids
dressed in green garbage bags were gathered in a shady park pouring muddy
water over piles of straw like dressing onto a salad, then tossing the straw
around until both kids and clay were coated with the clay slip. A creative
way to dampen pre-summer break energy? A devious plot to sell laundry
detergent?
Actually, I was watching the
construction of what may be Canada’s first straw-clay building, a ten-foot
diameter structure that builder Dan Boileau hopes will launch this ancient,
natural building technique into this country.
Once the kids had finished
mixing the straw and clay together, they stuffed it by handfuls into
two-foot high by one-foot thick plywood vertical forms around the perimeter
of a round stick frame structure. The mixture was compacted and poked
tightly into the corners of the forms. Many of the young builders
appeared
to enjoy this compacting process the most, some of them taking off their
shoes and socks, climbing inside the forms, and delightedly stomping the
straw and clay into submission. Later, the forms were removed and re-nailed
higher up the wall so the process could begin again.
Boileau took a break from mixing
clay slip and supervising his construction crew to describe the process. In
a month or two, when the wall has dried – “when the grass stops growing out
of the wall” is how he will know it’s ready – clay plaster will be added
both inside and out. The result will look like...
