flowing through the pipe - the products
bond monolithically into one solid piece.
" We're using the pipe in the ground, in
this case the culvert, to be a mold, if you
will, " said Michael Osborne, president
of Nukote. " The existing culvert that's
failing can continue to fail and when the
host pipe structure ceases to exist, we become
the pipe. "
The initial project bid, won by Aqua
Tech Solutions, was for a cementitious
product, which is typically sprayed on,
according to Waldron. Aqua Tech proposed
the use of Nukote polyurea, explaining
the benefits and that it's a relatively
new product in Ontario.
Nukote Coating Systems first approached
the city of Toronto in 2019
about reviewing its PP300 structural
liner. Trials conducted in July and
December 2019 went well, and when
this project was tendered, York Region,
which borders Toronto and is considered
part of the greater Toronto area, was
already familiar with the trials.
" It's kind of a multi-year build-up of
getting the product and lining system recognized
and then accepted for use within
the region, " said Aidan Logan, a sales
representative for IMC Distributors,
the US-based company's distributor in
Canada.
When Aqua Tech won the tender for
this culvert rehabilitation project, York
Region leadership decided to allow it to
proceed with using the polyurea. " This
was, as far as I know, the first culvert in
York Region that has been sprayed with
polyurea, " Waldron said.
