Saskatoon reaps the
rewards of resin relining
IVIS, located in Alberta, is a company pioneering new developments in underground infrastructure
solutions and pipe rehabilitation. IVIS recently embarked on a new project in Saskatchewan that placed
the company at the forefront of the western Canadian relining industry.
The project was initiated because
the City of Saskatoon’s potable water line
had experienced major failures, and was
becoming an on-going issue for residents.
It was evident the water line was in need of
repairs, and the City decided cured-in-place
pipe (CIPP) relining was an effective and lowcost
solution. The non-invasive technique
was selected because it would minimise
disruption to residents. Additionally, because
CIPP minimises the amount of excavation a
repair jobsite requires, worksite hazards for
installation crews are greatly reduced.
Size matters
The project required relining approximately
3,500 m of different sized pipes in the
city of Saskatoon, using CIPP technology.
This included the use of epoxy resin and
NordiTude liners.
The most challenging part of the project
was the distance between the wet-out
shop and the project site. Resin-filled liner
has a limited shelf-life; to avoid liner failure
on-site crews had to work efficiently and
complete all preliminary work before the
liner arrived at the project site.
Another issue the project faced was
the small services, which ranged in size
from three-quarters of an inch to one
inch. Locating these service holes and
reopening the connection in such a
small pipe requires superior skill that
few companies possess. Because of the
immense size and challenging nature of
this project, IVIS crews and management
came together to develop an innovative
solution.
About IVIS
The City of Saskatoon project expanded
IVIS into new markets. New production
strategies such as Just-In-Time and
reorganising the work system helped IVIS
expand its relining capabilities. IVIS is
a growing company that is expanding
its services throughout western Canada,
utilising new technologies in underground
infrastructure.
