PREMIER UNDERGROUND RENEWAL INFRASTRUCTURE SOLUTIONS

LiquiForce

The Next Generation of Lateral Lining

LiquiForce, a PURIS company, has been a leading provider of trenchless pipeline rehabilitation across Canada since 1987, offering CIPP, UV-cured solutions, geopolymer applications, manhole renewal, and more. Our vertically integrated model ensures efficient project delivery, quality control, and rapid response across wastewater, stormwater, airport, and industrial markets.

In 2026, LiquiForce entered a strategic partnership with Per Aarsleff (PAA) to strengthen and scale lateral rehabilitation capabilities throughout Canada. The partnership combines LiquiForce’s strong Canadian market presence with PAA’s global expertise, technical leadership, and advanced equipment innovations. As part of the agreement, PAA becomes a part-owner in the newly structured LiquiForce partnership.

No-Dig Lateral Rehabilitation, Raised to a New Standard

At LiquiForce, we’ve advanced no-dig pipeline rehabilitation to a new standard. Unlike conventional methods, our lateral rehabilitation process is fully trenchless and environmentally friendly. It cleans the existing lateral connection, measures it for a custom-made liner, and installs the new liner, all through the existing manhole and mainline sewer. No excavation, no existing cleanout, and no access to the home or business are needed, which means significant cost savings, shorter repair times, and minimal disruption. Our liner is designed to meet or exceed the standards for new pipe in durability and service life.

 
  • Broader access to high‑quality lateral lining solutions
  • Faster, more efficient delivery using advanced curing technologies
  • Combined global‑local expertise for stronger project outcomes
  • Enhanced reliability and long‑term performance for municipal and utility clients

How It Works

  1. Inspect. Once our preparation crew is on site, specialized video equipment is deployed from our robotic truck through the manhole and into the mainline sewer to determine the extent of deterioration.
  2. Clean and measure. The existing lateral is cleaned and measured so the new liner is custom-made to the exact dimensions and diameter of the existing pipe.
  3. Install. A flexible liner with styrene-free resin is installed directly from the main sewer. A camera-assisted installation unit ensures correct positioning.
  4. Cure. Patented LED technology provides fast, consistent curing, creating a jointless structural liner and sealing the connection to the main sewer to reduce infiltration.

The Result

A fully trenchless, watertight, structural renewal of the service lateral and its connection to the main sewer: a new, seamless pipeline inside the original host pipe.

Benefits

  • Faster, more efficient delivery using advanced LED curing
  • No excavation, cleanouts, or property access required
  • Combined global-local expertise for stronger project outcomes
  • Enhanced reliability and long-term performance for municipal and utility clients

Markets & Solutions

With offices across Canada, we have the resources to properly serve your underground infrastructure rehabilitation needs in the wastewater, stormwater, airport, and oil & gas markets. Our solutions include lateral lining, mainline CIPP, UV-cured CIPP, geopolymer applications, manhole renewal, and bypass solutions.

Stamford Interceptor Phase II Trunk Sewer

The primary scope of work on this project was to reline 1,560 meters of existing 1050mm diameter sanitary sewer located within an Ontario Power Generation canal along the high traffic Millennium Pedestrian Trail in the City of Niagara Falls. The work involved rehabilitation of 14 sewer segments and manholes. Four sewage pumping stations and local connections discharge in to the Stamford sewer. CCTV was used to identify corrosion in these sections. LiquiForce was responsible for developing and operating a bypass pumping system for these connections. All water used in the cure process was treated to reduce the styrene concentration prior to discharge.

Calgary Sanitary Sewer Lateral

The City of Calgary put together a lateral program to take advantage of the benefits of trenchless technology, including reduced social and environmental costs, reduced inconvenience to residents and local businesses, and a lower cost than traditional dig and replace methods. After working with engineers, This project included approximately 512 laterals. Cleanouts or other private property access was strictly prohibited. PFM (Prep From the Main) technology was built to avoid the use of cleanouts.

Hespeler Trunk Sanitary Sewer

The Hespeler Trunk Sanitary Sewer was constructed in the 1970s and feeds the Hespeler Wastewater Treatment Plant. The sewer lays entirely within Grand River Conservation Authority lands and includes an underwater crossing of the Speed River. This project included 5,000 ft of 24-27 inch diameter vitrified clay sewer main, 11 CIPP inversions ranging in length from 141-686 ft, and 16 manholes varying in depths up to 15 ft. The project included the installation of a bailey bridge for bypass purposes. All construction was completed within 65 working days.

South Service Road (Eastern Interceptor)

This deep sewer (30 feet), rehabilitation consisted of 435m of circular 60” 66” Trunk Sewer on the Eastern Interceptor. This line was suffering from invert damage of the entire length. In one location, localized repairs needed to be performed to stabilize a hole in the invert that was previously identified (3 ft wide x 4 ft long x 4 5 ft deep). The chosen repair method for this pipe was CIPP. Due to the liner weights and thickness, this installation required two OTH CIPP inversions. LiquiForce set up approx. 10,500 ft of 18” HDPE pipe to maintain the flows within the Eastern Interceptor.
