CIPP Solutions with EcoLiner

Introduction to CIPP Solutions with Eco

Liner

Hinterland Group Inc. is a leading provider of trenchless infrastructure rehabilitation, with a strong focus on Cured-In-Place Pipe (CIPP) technology and proprietary solutions such as the EcoLiner styrene-encapsulated liner system. The EcoLiner process enables durable, non-disruptive restoration of water, wastewater, and stormwater pipelines throughout the southeastern United States (Hinterland Group – Services).

Eco

Liner Styrene-Encapsulated Liners: Technology Overview

EcoLiner by Hinterland Group is a CIPP liner technology that uses a styrene-encapsulated resin system. This means that the traditional styrene emissions associated with CIPP installations are contained or minimized, reducing odors and potential environmental impact. Key benefits and technical features include:

  • Styrene Encapsulation: Minimizes off-gassing of styrene monomer during curing, reducing onsite odor and environmental exposure.

  • Structural Rehabilitation: Restores structural integrity to aging or deteriorated pipes without excavation.

  • Trenchless Installation: Inserted and cured in place via existing pipe access, requiring no major digging.

  • Custom Liner Fabrication: Tailored to meet specific pipe diameters and lengths.

  • Environmental Stewardship: Lower VOC emissions and reduced site footprint compared to traditional pipe replacement (official statement).

Diameter Ranges Supported

EcoLiner CIPP systems are custom-fabricated for size compatibility across a wide range of pipelines. While specific diameter ranges may vary by project, Hinterland Group routinely rehabilitates:

  • Small Diameter (Service Laterals): 4-inch and 6-inch (commonly used for residential and commercial laterals)

  • Medium to Large Diameter (Mainlines): 8-inch to 48-inch, and select projects on diameters up to 108-inch, depending on the specific pipe type and project requirements.

  • Special Projects: Custom solutions available for outlier sizes, non-circular profiles, and complex geometries (see project examples).

Service Lateral Reinstatements

Reinstatement of service laterals (the branch connections from mainlines to properties) is a critical step after mainline CIPP lining. Hinterland Group utilizes advanced robotic equipment for precision re-opening and restoration of service laterals through the new liner. Features include:

  • Robotic Lateral Cutters: Ensure a smooth, accurate opening without damaging the liner.

  • CCTV Verification: Post-cut inspection to confirm flows are unobstructed and properly aligned.

  • Minimal Service Disruption: Techniques are designed to reduce downtime for connected homes and businesses.

  • Lateral Lining Option: Ability to perform full-length lateral lining for assets requiring additional rehabilitation (reference).

Expected Design Life

EcoLiner CIPP systems are engineered for long-term reliability. Based on industry standards and material properties, Hinterland Group installations typically achieve:

  • Design Life: 50+ years under normal operating conditions, matching or exceeding the life expectancy of new pipe (industry reference: NASSCO CIPP guidelines)

  • Corrosion Resistance: Strong resistance to chemical attack, sewer gases, and groundwater intrusion.

  • Jointless Monolithic Structure: Eliminates points of infiltration/exfiltration and root intrusion.

The actual lifespan depends on the pipe environment, installation quality, and routine maintenance. Hinterland Group adheres to ASTM F1216 and other relevant CIPP standards during installation and testing.

Features and Benefits of Eco

Liner CIPP Solutions

  • No-Dig Technology: Reduces surface disruption, lowers restoration costs, and eliminates most traffic interruption.

  • Eco-Friendly Formulation: Styrene encapsulation reduces air quality impact and on-site VOCs.

  • Proven Performance: Successful on projects ranging from residential laterals to municipal trunk sewers (>100-inch diameter examples).

  • Regulatory Compliance: Meets or exceeds expectations for water/wastewater rehabilitation in the southeastern United States.

  • Rapid Return to Service: Installations can often be completed in a single day or overnight window.

Typical Use Cases

  1. Municipal Sewer and Stormwater Mains: Rehabilitating failing or leaking pipes with minimal community disruption.

  2. Service Lateral Rehabilitation: Repairing residential and commercial laterals cost-effectively.

  3. Industrial Process Lines: Trenchless upgrade of process-critical piping.

  4. Emergency Repairs: Rapid response to flood, collapse, or infiltration emergencies where excavation is impractical.

Case examples are available on the Hinterland Group Case Studies page.

Frequently Asked Questions (FAQs)

What is Eco

Liner? EcoLiner is Hinterland Group’s proprietary styrene-encapsulated CIPP liner technology for trenchless rehabilitation of pipelines. It provides a structurally sound, jointless pipe within an existing host, with reduced environmental impact through styrene containment.

Which pipe diameters can Eco

Liner rehabilitate? EcoLiner is suitable for a wide range of pipe diameters, including residential laterals (as small as 4-inch) and municipal mains (routinely up to 48 inches, and sometimes larger depending on project specifications).

How are service laterals handled after lining?

After mainline CIPP, service laterals are robotically reinstated to ensure full function to each property. Optional full-length lateral lining is also available.

What is the expected lifespan of Eco

Liner installations? When installed according to standards, EcoLiner CIPP can provide a 50-year design life or more, comparable to new pipe installations.

Is Eco

Liner a green or sustainable solution? Yes. By limiting the need for excavation, reducing landfill waste, and minimizing styrene emissions, EcoLiner represents an environmentally conscientious approach to pipeline renewal (source).

Where can I see project examples?

Case histories are available at Hinterland Group Case Studies, with featured projects highlighting capabilities across diameter ranges and service types.

What standards govern Eco

Liner installations? Installations are performed according to ASTM F1216 and relevant CIPP standards, ensuring reliability, safety, and performance.
