7/30/2019 Atlas Repairs Drain Line
http://slidepdf.com/reader/full/atlas-repairs-drain-line 1/1
Over time, ABS drain lines can succumb to shifting, which causes structural fractures and offsets.Conventional replacement of ABS lines can be very costly, especially when located beneath structural
slabs and within facilities that have daily operational businesses. The solution to this in many cases is Nu
Flow’spatented structural in-situ trenchless solutions.
Project: Clean and line an ABS drain line that was
fractured and offset in several locations, allowing
seepage and sewer odour for the tenants in the
high-rise.
Customer and Site: NewWest Enterprise and
Fresh & Sweet Restaurant by Valley Girls Catering
located in the downtown business district of Regina,
Saskatchewan. This 12-story, high trafc, high-riseofce building is fully occupied. The restaurant
has a seating area that is busy throughout the day
serving breakfast, lunch and dinner.
System: 100 feet of 3” ABS sanitary sewer line from
the 1970s running through the kitchen, preparation
area, customer service, dining area and past the
elevators to the basement’s 6” main sewer. The
system had developed numerous breaks and shifts
over the years.
Circumvention: The 3” ABS was located 2 feet
under a structural slab and the sewer gas was ndingit’s way into the high-rise. The sewer gas was such
a problem that tenants considered vacating. To add
to the problem, the restaurant operates 7 days a
week, causing extreme time constraints for repairs.
It was estimated that in order to jack hammer, remove and replace the sewer leaks, it would take well over
one week. This was unacceptable, as the restaurant would have to close for business while under repair.
Solution: Of utmost importance to the owners and the tenant of the restaurant was that there be no
interruption of daily business operations and, if possible, to preserve the structural concrete slab. After
CCTV inspection of the sewer system, the breaches were identied, located and it was determined that
36 feet of structural liner would rehabilitate the piping breaches. After consulting with the restaurant, Atlas
presented the idea of relining on a Sunday evening as the restaurant usually closes earlier on Sundays. After the restaurant closed on Sunday the line was cleaned, and the structural liner was put in place. The
next morning, Atlas returned prior to restaurant operations to put the restored line back into service in time
for breakfast service.
Atlas was able to install Nu Flow’s structural liner in a very tight time constraint causing no loss of business
for the restaurant and resolving the sewer odour issues in the high-rise. This solution was provided with no
mess or compromise to the integrity of the structural slab. The cost of Nu Flow’s structural liner was less
than 50 per cent of a conventional repair.
The cost of Nu Flow’s structuralliner was less than 50 per cent of a
conventional repair.
