Project Summary

A large trenchless contractor from Ontario was installing Cured in Place Pipe (CIPP) in lateral sewers to homes when they had a liner failure that blocked of a homeowners sewer.  The contractor didn't have any means to cut out the failed liner, so they were going to have to excavate the front of the property.  The upset homeowner got the city's project management team involved and they contacted Revive Pipes.  We used on of our robotic cutters through the homes cleanout access and cut out the complete blockage created by the other contractors Cured in Place Pipe (CIPP) liner.

“A Trenchless contractor should have specialized equipment to be able to correct most mistakes without resorting to excavating as a first option.  As with all contractors, we’ve made mistakes. We’ve just made an expensive and conscious decision to minimize disruption to our clients when correcting them.”Brendan Macfarlane, President, Revive Pipe Restoration Inc.

Situation

A lining contractor had a contract with a Western Canadian city to install liners in several residential service laterals.  Unfortunately, the contractor couldn’t get a liner to expand properly prior to curing it and the sewage flow from a home was completely blocked off.  The lining contractor didn’t have any trenchless means to fix the problem and so was going to have to excavate to repair the mistake.  The mistake was in a very challenging location and would have been prohibitively expensive to excavate and the property owner had no desire to have their yard dug up.

Typical Invasive Repairs

The NON-Trenchless repair that the Trenchless Contractor was planning to employ was an excavation in the front yard of the property.  This would have involved:

  • Tearing down the decorative picket fence
  • Removing retaining walls in the terraced garden
  • Digging down to the section of the sewer that was blocked off by the other contractors Cured in Place Pipe (CIPP) liner
  • Cutting out the sewer pipe
  • Installing a new sewer pipe
  • Backfilling the excavation and compacting it
  • Rebuilding the retaining walls
  • Hiring a professional landscaper to try to replicate the homeowners care and attention to detail in planting and nurturing the ornamental garden that was torn out
  • After a year, there likely would have been settling of the blackfill and it would have to be refilled
  • Rebuilding the fence
