Chemical grouting is
a low cost alternative to complete rehabilitation of
pipelines.
It is the best and most economical method for battling
infiltration of sewer systems. Sewer Technologies can
help eliminate infiltration at joints, laterals, or cracks
using chemical grouting procedures.
For the repair of joints a
"packer" is pulled through the sewer line, stopping at each
joint or crack. A pressure test will then be performed. If
the pressure test passes the packer will move to the next
joint or crack. If it fails the test, Urethane grout will be
injected.
These chemical grouting
processes are televised and recorded by a CCTV camera truck
on site. "Before and After" videos are provided on Compact
Disc and/or VHS tapes to the customer.
