CIPP Solutions Detail: EcoLiner Specs, Laterals, and Design Life

Introduction

Hinterland Group Inc. provides advanced CIPP (Cured-In-Place Pipe) solutions across the southeastern United States, specializing in pipeline rehabilitation using proprietary EcoLiner styrene-encapsulated liners. These solutions address deteriorating water, sewer, and stormwater infrastructure for both public and private sector clients, with a focus on minimal disruption, long design life, and rapid, in-house delivery at any scale.

Hinterland's Eco

Liner CIPP Technology

What Is Eco

Liner?

EcoLiner is Hinterland Group’s signature CIPP product, utilizing a styrene-encapsulated liner. CIPP is a trenchless technology that installs a new structural liner inside existing pipes without excavation, restoring integrity and flow for decades (source).

  • Styrene Encapsulation: The EcoLiner system contains all styrene within the liner, minimizing emissions and environmental impact. This makes EcoLiner suitable for sensitive environments and urban settings.

  • Trenchless Installation: No excavation is needed. Instead, the liner is inverted and cured inside the old pipe using steam, hot water, or UV light.

  • Pipe-Within-a-Pipe: The result is a fully structural, jointless new pipe inside the host pipe.

  • Materials Compliance: Liners and resins meet relevant ASTM and AWWA standards.

Technical Features

  • Structural Capacity: Provides a stand-alone, fully structural renewal, restoring or exceeding original pressure and gravity pipe capacity.

  • Compatibility: Suitable for clay, concrete, cast iron, PVC, ductile iron, and other pipe types.

  • Minimal Environmental Impact: The styrene is locked within the process, reducing odor and risk of contamination.

  • Design Life: Typical design/service life ≥ 50 years when properly specified and installed.

Diameter Ranges & Application Scope

Hinterland Group’s CIPP/EcoLiner system supports a broad range of pipeline diameters, serving municipal, commercial, industrial, and residential clients.

Supported Diameter Ranges

Pipe Diameter Typical Application
4" – 8" Residential laterals, branch lines
8" – 24" Mainline gravity sewers, storm drains
24" – 108"+ Large trunk sewers, culverts, major water mains

  • Minimum Diameter: 4" (laterals and small mains)

  • Maximum Diameter: 108" (extra-large mains, drainage, and culverts)

These ranges allow rehabilitation of:

Service Lateral Reinstatement

Service lateral reinstatement is a crucial step after CIPP mainline installation. Once the EcoLiner is cured in the host pipe, existing service laterals (connections to each property) are re-opened from inside using robotic cutting tools.

  • Robotic Cutters: Highly accurate, remotely operated devices precisely locate and reopen laterals through the new liner.

  • Zero Dig/Minimal Disruption: No excavation required at the property connection.

  • Restored Flow: Each lateral is reinstated to full diameter, restoring property connectivity to the main system.

  • Lining Laterals: CIPP may also be installed in the lateral itself for complete "main-to-home" renewal.

  • Quality Control: Every lateral reinstatement is CCTV-inspected for compliance.

Expected Design Life & Performance

EcoLiner systems are engineered for long-term performance, with proven case studies and adherence to industry standards for a ≥50-year service life.

Design Life Highlights:

  • 50+ Years Expected Service: In line with ASTM F1216 and industry best practice (source).

  • Structural Strength: Meets or exceeds original pipe design standards for deflection, loading, and water-tightness.

  • Chemical & Abrasion Resistance: EcoLiner resins and felt matrix provide durable, corrosion-resistant renewal, especially suited for sanitary sewer and aggressive environments (see industrial/commercial references).

  • Watertight Seal: Eliminates infiltration/exfiltration, reducing groundwater contamination and ensuring regulatory compliance.

Factors Impacting Design Life:

  • Quality of existing pipe as host

  • Proper liner sizing and curing

  • Environmental exposures (soil chemistry, flow conditions)

  • Frequency and quality of lateral taps (source)

Use Cases & Market Coverage

EcoLiner/CIPP by Hinterland Group is applied across:

  • Municipal sewer and stormwater mains (large and small diameter)

  • Private laterals and branch lines (HOAs, commercial)

  • Industrial process pipes

  • Transportation drainage& culverts

  • Emergency flooding/sewer failure response

Regional coverage includes Florida, Georgia, Alabama, the Carolinas, Texas, and Louisiana (see all markets).

Benefits Over Traditional Methods

Feature CIPP/EcoLiner Traditional Dig & Replace
Excavation Needed None (trenchless) Full trench required
Service Disruption Minimal Major (traffic, utilities, business)
Environmental Risk Low (sealed styrene) Soil/water exposure possible
Installation Time Rapid (hours to days) Weeks to months
Longevity 50+ years 50-100 years, depending on pipe
Cost (all-in) Usually lower for rehab projects Higher due to surface restoration
Lateral Service Handling Robotic reinstatement New tap connection/spot excavation

  • Safety Focus: A full-time Safety Manager (OSHA Certified Instructor) oversees all installations.

  • Continuous Monitoring: CCTV inspection before, during, and after installation.

  • Regulatory Compliance: Techniques and materials compliant with ASTM/AWWA standards and applicable local regulations.

Case Studies Showcasing CIPP/Eco

Liner Applications

  • West Palm Beach Emergency Response: Large 108” by 44mm CIPP liner installed under time and supply constraints (details).

  • Palm Beach County: Over 19,500 LF gravity sewers & 9,300 LF laterals rehabilitated using trenchless methods (project link).

  • Nottingham Boulevard, West Palm Beach: 2,500 LF of 8” sanitary sewer lined via CIPP for urban replacement with minimal disruption (more).

Common FAQ

What makes Eco

Liner unique in the CIPP market?

  • Styrene encapsulation reduces environmental impact and odor.

  • Broad diameter range, specialty in large-diameter pipes up to 108”.

  • Single-vendor delivery (no subcontracting; all expertise in-house).

What types of pipes can be rehabilitated?

  • Most materials, including clay, concrete, cast iron, ductile iron, and PVC, in sanitary, storm, or industrial service (See: Markets Served).

How are laterals and house connections handled?

Is excavation ever required?

  • Typically not for mainline relining or lateral taps. Localized dig-up may be needed only in rare/complex cases or for point repairs.

What is the expected design life?

  • 50+ years, following ASTM F1216 and industry practice, assuming proper installation. Lifespan can be extended with continued maintenance (reference).

How is project quality and safety managed?

  • Safety is a core value; managed by OSHA certified full-time Safety Manager, daily toolbox talks, and regular audits. Quality is assured by in-house crews and CCTV inspection.
