Pipe Rehabilitation (CIPP)

Renew assets without replacement—CIPP liners and spot repairs for water, wastewater, and industrial lines.

Overview

Extend service life. Minimize disruption.

We install cured-in-place liners and sectional repairs to address infiltration, corrosion, and structural defects—without open-cut. Our crews manage bypass, reinstatements, testing, and handover so assets return to service quickly.

  • Full-length CIPP liners and sectional point repairs
  • Hot water, steam, or UV cure per project need
  • Service reinstatement with robotic cutters
  • Pressure/leak testing & full close-out documentation

Full-Length CIPP
  • Negotiates bends & diameter changes
  • Structural renewal for deteriorated mains
  • Water, wastewater, industrial applications
  • Design thickness per loads & ovality
Sectional Point Repair
  • Targeted defect repair (roots, cracks, joints)
  • Minimal bypass and short cure times
  • Cost-effective for isolated failures
  • Compatible with future full liners
Cure & QA
  • Hot water / steam / UV cure methods
  • Continuous temperature & pressure logs
  • Post-cure CCTV + coupon testing
  • Pressure/leak & mandrel tests (as required)

Process

From planning to reinstatement

Tight controls produce consistent cures and reliable records.

01 • Survey & Design

CCTV review, host pipe condition, liner thickness & resin selection.

02 • Bypass & Prep

Flow isolation, cleaning, calibration tube (if required), site controls.

03 • Inversion/Pull-In

Liner positioned and pressurized for uniform placement.

04 • Cure & Log

Hot water/steam/UV cure per spec with continuous data logging.

05 • Reinstatement

Robotic cutters open laterals/taps, edges dressed.

06 • QA/QC & Handover

Final CCTV, testing, cure logs, as-builts, and GIS package.

Case Study — 1.8 mi CIPP Program

Suburban trunk sewer rehab (18"–30") with multiple creek crossings. Steam-cured liners and sectional repairs minimized excavation and road closures.

  • All segments delivered with cure logs & post-CCTV
  • Bypass maintained service; no SSOs during works
  • GIS updates and PDF package used for close-out

Owner Benefits
  • Avoids open-cut restoration costs and community impact
  • Structural renewal with predictable service life
  • Data-rich close-out for easier future maintenance
  • Compatible with phased rehab programs
FAQ

CIPP questions, answered

Design, curing, and how services are reinstated.

We evaluate diameter, length, access, flow conditions, and resin system. Steam is efficient for many diameters; UV is excellent for precise, fast cures where access allows a light train.

Typically no. We plan bypass pumping or low-flow windows. Laterals are robotically reopened after cure and verified by CCTV before handover.

Cure logs (temperature/pressure), resin batch info, post-cure CCTV, test results, as-builts, and optional GIS deliverables—organized for your records.
