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:

• Residential and commercial laterals

• Gravity sewer and water mains

• Stormwater pipelines

• Industrial process piping

• Culverts and large-diameter infrastructure (Regional CIPP Specs; https://hinterlandgroup.com/services/)

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

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?

• Robotic lateral cutters reinstate every service connection with precision, fully restoring residential and commercial flows (see CIPP careers, tap cutter roles).

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.
