Trenchless Pipeline Rehabilitation
Cured-in-place pipe lining and slip-lining for commercial facilities, engineered to Canadian civil standards.
Commercial projects completed
Single-run structural liner capacity
Design life per CSA standards
Post-installation CCTV verified
Canadian civil engineering standards
Commercial facilities stay operational during repairs. No trenching means no lost parking, no blocked loading bays, and no disrupted tenant access.
Typical project: 2–3 night shiftsCured-in-place pipe (CIPP) and HDPE slip-lining meet CSA B182 and ASTM F1216 standards. The restored pipe carries full structural load without future corrosion.
Design life verified by post-install CCTVInternal lining eliminates root intrusion, joint displacement, and tuberculation. Hydraulic modelling confirms the renewed pipe handles peak storm and sanitary loads.
100-year event rating achievedEpoxy and liner materials used for potable water mains are certified for drinking water contact. Final water sampling meets Health Canada guidelines.
Lead solder concerns eliminatedTemporary bypass systems maintain sewer and water service throughout the lining process. Retail, office, and industrial tenants never notice a disruption.
Phased work per building scheduleEvery project follows OBC Part 7 and local municipal standards. Inspection reports and hydrostatic test results are submitted directly to the authority having jurisdiction.
Full documentation package includedStructural rehabilitation for commercial and municipal pipe networks — CIPP, slip-lining, and spray-applied epoxy systems engineered to Canadian civil standards.
Full structural liner for cast-iron, clay, and concrete mains up to 36-inch diameter. Installed through existing manholes with no excavation. Rated for 50-year design life per CSA B182.11.
Reinforced HDPE insertion for storm and sanitary lines with longitudinal cracks or joint displacement. Bypass pumping and robotic lateral cutting included. Meets Ontario municipal stormwater management criteria.
NSF/ANSI 61-certified epoxy for potable water mains and fire-suppression lines. Restores flow capacity and eliminates tuberculation without disrupting building occupancy. Complies with Health Canada drinking water guidelines.
Hydraulic bursting of existing brittle pipes to install a larger-diameter HDPE or ductile iron replacement. Suitable for undersized laterals and mains in dense commercial zones. Minimal surface disruption.
Precision cutting and sealing of service connections from inside the main line. No excavation at the property line. Restores full flow to building drains within hours.
Full-length camera inspection and pressure testing after every rehabilitation. Deliverables include digital log, defect mapping, and compliance report for municipal or insurance review.
Visual reference
Internal camera survey revealed severe corrosion and root intrusion in a 300‑metre main beneath a Toronto commercial tower. The inspection footage guided liner thickness and resin selection per CSA B181.2.
Structural felt liner impregnated with epoxy resin was winched into the existing pipe. Three night shifts allowed the 12‑storey building to operate normally during business hours. Post‑cure CCTV confirmed a jointless interior.
A 48‑inch concrete storm drain in Mississauga had longitudinal cracks from soil settlement. Reinforced HDPE pipe was pulled through the existing line without excavating warehouse loading areas. Bypass pumping kept the site dry throughout.
A 40‑year‑old ductile iron water main in Vancouver was lined with NSF/ANSI 61‑certified epoxy. The process restored flow and eliminated lead solder concerns while retail and residential units stayed operational. Final water samples met Health Canada guidelines.
After slip‑lining, a remotely operated robotic cutter reopened each lateral connection inside the storm drain. The process avoided excavation and maintained full drainage capacity for the industrial park’s 100‑year storm event design.
Every rehabilitated pipe underwent a full CCTV scan and hydrostatic pressure test. The results were documented per Ontario Building Code and CSA standards, providing the client with a 50‑year design‑life warranty.
