1. Nu Flow, the world’s leading inside-infrastructure corporation, avoided destruction and occupant displacement at
the Grossmont Shopping Center in La Mesa, California, while rehabilitating a failing cast iron piping system with a
pipe retrofit.
Project: Retrofit the lateral sewer line located
inside a mall under a Starbucks and Barnes &
Noble store, without disruption to tenants.
Customer: CB Richard Ellis, a global leader in
real estate services and property manager for the
Grossmont Shopping Center.
Site: Grossmont Shopping Center, La Mesa,
California, a 939,000 square foot, single-level
outdoor center.
System: The lateral sewer line consists of 60 feet
of 4” cast iron pipe installed in 1961. The line runs
under the middle of the Barnes & Noble sales floor
to the Starbucks.
Situation: Corrosion of the cast iron sewer line
resulted in chronic failure including clogging and
multiple backups that required a plumber to clear.
Camera inspections revealed that the bottom of
the pipe had a large hole.
Solution: First, Nu Flow cleared the corrosion
inside the pipe, returning it to its original inside
diameter. Once complete, the pipes were retrofitted
with the patented Nu Flow process by pulling a
seamless structural liner into place, extending
the pipes useful life. Nu Flow performed the work
after mall hours to avoid disruption to the mall’s
operations with a procedure that did not require
digging through the floors and foundation.
Aged and failing pipe systems are common in commercial, industrial and residential buildings. Whether you are
experiencing problems now or are interested in preventing the inevitable failure of your plumbing system, Nu Flow
is available to restore your peace of mind.
“As opposed to using traditional methods
of replacing the failed portion of pipe and
inconveniencing our tenant, we chose to hire
Nu Flow to line the interior of the pipe with
an epoxy. We completed this work over two
years ago and have not experienced an issue
since.”
