Trenchless Rehabilitation

IVIS Inc. provides trenchless sewer and pipe rehabilitation using cured-in-place pipe (CIPP) technology. CIPP by definition is a rehabilitation (of a damaged or defective pipe) technique whereby a flexible thermosetting resin impregnanted tube is installed (either by inversion or pull-in-place) into an existing pipe and then cured to a hard finish.  This cured pipe usually assumes the shape of the existing pipe and forms a jointless, seamless, tight fitting liner within its host pipe.  The fundamental principle behind the CIPP process is that the deficient underground infrastructure piping is relined as opposed to the conventional digging, removing and replacing with new pipe.

 

 IVIS Inc. has the capability to rehabilitate pipes ranging in diameter from 2 inches –120 inches. As one of the most widely used rehabilitation methods, CIPP has application in water, sewer, gas, manhole, culvert and chemical pipelines.[1]

 

IVIS Inc. has the capabilities to reline both main and lateral line connections.  All of our CIPP installations are environmentally friendly and socially responsible; services are fully functional within a matter of hours compared to days with other rehabilitative techniques. CIPP offers a cost effective solution for sewer line and manhole replacement compared to conventional dig and replace techniques. 

Trenchless pipe relining offers minimal impact on the surrounding environment and is a permanent solution to pipe corrosion, deformation, infiltration, inflow and exfiltration. It also provides the benefit of long-term, complete structural rehabilitation, even in scenarios where the host structure is fully deteriorated (as the lining can be manufactured to serve as a fully engineered pipe replacement). 

 

IVIS Inc. main and lateral line CIPP rehabilitations are compliant with ASTM standard F1216 - a flexible, resin impregnanted tube is installed in the conduit via inversion with air pressure and cured to a hard, continuous, tight fitting finish with steam.  Our T-Liner product is compliant with ASTM standard F2561 - in that is provides a one piece, full wrap liner seal for the main to lateral interface.

Types of sewer services we use Cured in Place Pipe

 

Lining a manhole or culvert
  • IVIS Inc. is the exclusive licensee of the Poly-Triplex® Liner System in Canada. The patented Poly-Triplex® Liner System is a cured-in-place structural liner that is designed to provide 100 years of structural integrity.

 

  • This solution includes design, engineering and installation of a CIPM liner made of multiple layers of load bearing laminates. Each liner is saturated in a thermo-setting, epoxy resin and is backed with up to a 20-year materials warranty.

Main Line CIPP - Lining storm sewer, sanitary sewer and other gravity or pressure mains (4" - 120" diameter)
  • For 4” to 120” diameter pipes we offer a resin impregnated, felt liner CIPP solution that is ASTM 1216 compliant. The liner is wet out with a thermo-setting polyester resin.  "Wetting Out" refers to dry liner impregnation with thermo activated resins - our liners are wet out inside out for inversion installation. 
  • We are capable of "wetting out" in-house and/or “over the hole”.

 

  • We also offer, as a preferred licensee of Pacific MultiLiner CIPP products, a "pull in place" fiberglass liner designed for outstanding structural integrity, minimized wall thickness and a fast curing time for 6" - 48" diameter pipe.

Lateral/serivce Line CIPP - Lining a storm sewer, sanitary sewer and lateral sewer lines (3" - 18")
  • For our lateral service installations, IVIS Inc. uses LMK Enterprises Performance Liner®, T-Liner® and Vac-A-Tee® technologies. These are all permanent repair solutions that allow for the cost-effective structural relining of existing service lateral sewer lines and lateral to main connections with a verifiable, non-leaking connection (VNLC) that is impervious to root intrusion and infiltration.

 

  • For circumstances when cured in place pipe solutions may not be applicable, we offer trenchless solutions for sewer, water and commercial lines from 3" - 12".

 

 

Pipe Bursting
  • A trenchless technology for the replacement of severely damaged factory-manufactured pipes. Pipe bursting involves the creation of both an insertion and pulling pit to facilitate fragmentation of the damaged piep and installtion of new pipe (of the same or larger diameter).  A hydraulically powered busrting unit is inserted into the defective pipeline and as it travels through the pipe it breaks up the old pipe into small pieces while pulling a new pipe into place.


The benefits of pipe bursting are:

  • Path and slope of the new pipe does not change. This technique offers minimal grade correction for sagging pipe.
  • Existing deformed pipe does not require disposal since it is displaced by the new pipe.
  • Pipe flow capacities can be substantially increased by “upsizing” to new pipe diameters.
  • There is minimal impact on the environment.
