At TrenchFree, we prioritize sustainable infrastructure solutions that protect the environment and your community. Our Cured-in-Place Pipe (CIPP) rehabilitation technology eliminates the need for wholesale excavation, reducing soil disturbance, traffic disruption and carbon emissions. By re-using existing pipe routes and minimizing energy use by machinery with trenchless repair, you’re choosing a greener, cleaner option.
What is Cured-in-Place Pipe (CIPP)?
Cured-in-Place Pipe (CIPP) is a cost-efficient, jointless rehabilitation method that extends the life of existing sewer lines without digging. This trenchless solution restores pipe integrity, improves flow quality and eliminates infiltration and exfiltration at the repair site—all while preserving the surrounding environment.
Unlike full pipeline replacement, CIPP spot repair targets only the damaged sections. For example, if a 300-foot sewer line has just 18 feet of damage, CIPP allows precise restoration of that segment alone, saving time, money, and resources.
The TrenchFree CIPP Process
Our streamlined CIPP rehabilitation process minimizes downtime and disruption:
• Access & Preparation – Technicians enter the pipeline via the nearest manhole or cleanout.
• Cleaning – A high-velocity jetter removes all debris from the pipe.
• Inspection – A video camera locates the exact damage.
• Repair – An uncured resin-saturated felt tube is inserted and positioned at the damage site.
• Curing – The tube is pressed against the pipe’s inner wall using hot air or water pressure, then cured in place (typically 2–4 hours).
• Completion – The bladder is deflated, removed, and the repaired pipe is ready for service.
Key Benefits of CIPP
✅ Environmentally Friendly – Reduced excavation means smaller carbon footprint, preserved landscaping and minimal community disruption
✅ Cost-Effective – Lower labor and material costs compared to traditional replacement
✅ Extended Lifespan – Adds 50+ years of service life to existing pipes
✅ Minimal Disruption – No digging, traffic delays or damage to structures
✅ Precision Repairs – Targets only the damaged sections, not the entire pipeline
Testing Standards & Quality Assurance
At TrenchFree, we ensure every CIPP installation meets the highest industry standards. Our materials and processes comply with rigorous third-party testing, including:
• ASTM F1216 – Standard Practice for Rehabilitation of Existing Pipelines and Conduits by the Inversion and Curing of a Resin-Impregnated Tube
• ASTM D790 – Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics
• ASTM D5813 – Standard Specification for Cured-in-Place Thermosetting Resin Sewer Pipe
• ASTM D3567 – Standard Practice for Determining Dimensions of Fiberglass (Glass-Fiber-Reinforced Thermosetting Resin) Pipe and Fittings
• ASTM D2122 – Standard Test Method for Determining Dimensions of Thermoplastic Pipe and Fittings
As an ISO 17025-accredited partner, we guarantee that your CIPP installation not only meets regulatory requirements but also protects your infrastructure and the environment.
