Trenchless Technologies (CIPP)

Industry Leader in Trenchless Pipe Rehabilitation

IVIS Construction Inc. is a Canadian industry leader in trenchless pipe rehabilitation, using Cured-In-Place-Pipe (CIPP) to repair existing infrastructure in manholes, storm lines, sanitary lines, culverts, laterals, and catch basins.

No-Dig Trenchless Pipe Rehabilitation

  • Trenchless pipe rehabilitation offers a minimal impact on the surrounding environment and provides a long-term solution to pipe corrosion, infiltration, and ex-filtration.
  • This process involves complete structural rehabilitation, as the cured pipe assumes the shape of the existing pipe and forms a joint-less, seamless, tight-fitting liner within its host pipe.
  • At IVIS Construction Inc. we are capable of rehabilitating pipes ranging from 3in to 72in in diameter and can re-line main and lateral line connections.
  • With the trenchless pipe rehabilitation method, the pipe is returned to service within hours as opposed to days with other rehabilitation methods.

Trenchless Rehabilitation: Lateral Renewal Systems

IVIS Inc. is an LMK Technologies We can provide our customers with a watertight, root-tight lateral pipe repair solution that is engineered to a service life of up to 100 years.

Performance Liners (ASTM 1216)

LMK performance liners are structural, stand-alone liners that are saturated with resin, inserted into the pipe, and then cured. These liners are installed in secondary services from the house to the main line.

What are the benefits?

  • Lateral Renewal System.
  • Spot repairs from 100mm up to 600mm.
  • The liner can be inserted anywhere in the pipe with no trimming or cutting.
  • Watertight, root-tight.
  • Resin saturated, inserted, and cured.
  • Structural stand-alone lining.
  • An engineered service life of 100 years.

T-Liners (ASTM F2561)

LMK’s T-Liners are a one-piece homogeneous main and lateral Cured-In-Place-Pipe (CIPP) connection liner saturated with resin. Both the mainline and lateral sections are formed as a structural cylinder that renews 360-degrees of the mainline and extends up the lateral pipe as one continuous lining.

What are the benefits?

  • Non-disruptive, effective, and efficient.
  • Watertight, root-tight main/lateral lining.
  • Resin saturated felt liner that can be air inverted.
  • Renew laterals up to 61m in a continuous inverted liner.
  • Structural stand-alone lining.
  • An engineered service life of 100 years.
  • Custom tailored for pipe transition from one size to another
  • Uniform Wall Thickness.
  • Compressible material at the ends creating a smooth, tapered transition to the host pipe.
  • Lateral lining up to 200 feet long.

Additional Clean Out


At IVIS Construction Inc., we use LMK’s VAC-A-TEE clean-out system when there is no access to the line inside of the building. This system provides us with an alternative clean out to the main line, prior to installing the T-Liner.

This trenchless clean-out system is a clean and safe method for installing a new clean out, which provides access to the sewer lateral pipe for cleaning, lining, root removal, CCTV, and more.

What are the benefits?

  • A trenchless clean-out system for pipes ranging from 100mm – 600mm.
  • Main pipe (140mm – 600mm).
  • Lateral pipe (75mm – 200mm).
  • Clay PVC, non-corrode, and cast iron.

Potable Water

SEKISUI Liners (ASTM 1216)

Sekisui liners are a high quality, glass-fibre reinforced Cured-In-Place-Pipe (CIPP) liner. IVIS Inc. recommends the use of these liners when dealing with issues regarding potable water.

This liner is saturated with a specially designed thermosetting resin, inverted into the deteriorated pipe with water or air, and cured to a superior liner of high stiffness and quality.

This liner can withstand high internal and external pressures, is available in a variety of sizes, and is proven to improve flow characteristics.

What are the benefits?

  • Reinforced pipe liner will withstand high internal/external pressure.
  • Pipe re-lining from 150mm to 600mm in diameter.
  • Up to 244m per installation.
  • They are manufactured in lengths over 1,000 feet.
  • Liners can withstand pressures of up to 200 PSI.
  • Liners can bend up to 45 degrees.
  • Granted potable water approved with AS/N Zs3020, BS6920, NSF61, BNQ applications.

Manhole, Catch Basin, Lift Station, and Culvert Relining

MCNEIL Technologies Triplex Liner Renewal System

The Triplex liner is recommended for manhole and culvert rehabilitation. This triple layer protection liner is proven to solve issues with deterioration and infiltration.

Installation takes only a few hours, which means we can install an average of 2-4 manhole/ culvert structures per day.

Triplex Liners are made of structural fibreglass and polyester felt, with an internal non-porous membrane, providing a flexural strength that is bonded to the host structure. The structural integrity of the host structure is restored, and further infiltration and chemical deterioration is prevented.

What are the benefits?

  • Custom designed manhole liner.
  • 10-year warranty on materials and labour.
  • Reduces the volume of wastewater treated.
  • Eliminate 100% of the groundwater infiltration.
  • Lift stations, catch basins, manholes, and culverts.
  • An engineered service life of 100 years.
