Overview of CIPP Solutions with Eco

Liner by Hinterland Group

Hinterland Group is a leading provider of advanced trenchless pipeline rehabilitation services across the southeastern United States. A cornerstone offering is Cured-In-Place Pipe (CIPP) rehabilitation, including the proprietary EcoLiner styrene-encapsulated liner system. This page details the technical specifications, diameter ranges, laterals approach, typical service life, and project applications of Hinterland Group’s CIPP with EcoLiner solution (source).

CIPP with Eco

Liner: Technical Summary

Technology Description

Cured-In-Place Pipe (CIPP) is a trenchless method for rehabilitating existing pipelines. It involves inserting a resin-saturated felt or fiberglass liner into a host pipe, inflating it, and curing in place (typically by hot water, steam, or UV light) to create a new structural pipe within the existing line.
Hinterland Group’s EcoLiner is an advanced CIPP liner, utilizing styrene-encapsulation technology for improved environmental performance and decreased odor migration during curing (source).

Environmental and Health Advantages

Styrene Encapsulation: Reduces potential emissions during installation, lowering environmental impact and improving safety for nearby residents, particularly in urban and sensitive zones.
Zero-Dig Approach: Minimizes surface disturbance; suitable for historic, commercial, airport, HOA, and critical municipal infrastructure (source).

Diameter Range and Application Scope

Hinterland Group installs EcoLiner CIPP in diameters from 4 inches (100mm) up to 108 inches (2,743mm), supporting a vast array of pipeline networks, including:
Sanitary sewer mains
Stormwater systems
Industrial lines
Water mains (select applications) (source, source)

Pipeline Type	Diameter Range Supported
Service Laterals	4"–8"
Gravity Sewers	6"–108"
Storm Drains	12"–108"
Culverts	as large as 108" (rectangular and round)

Service Lateral Reinstatement

Lateral Reinstatement:
After mainline CIPP installation, all lateral services (e.g., home or building sewer connections) are reinstated using specialized robotic cutters.
Hinterland Group employs trained "tap cutters" to reopen and ensure flow from each lateral into the lined main (source).
Laterals may also be relined with CIPP where needed, typically 4"–8" diameter.
Benefits:
No excavation required to restore laterals
Fast return-to-service for residents/businesses
Minimized risk of missed connections (robust QA/QC protocol)

Design Life & Longevity

Typical Design Life:
Standard CIPP installations, including EcoLiner, are engineered for a 50-year design life under industry norms (ASTM F1216), with proper material quality and installation.
Actual Service Life:
Real-world performance often matches or exceeds this period when pipelines are maintained as recommended.
Warranties Offered:
Hinterland typically provides a limited warranty (duration varies per project/spec), supported by documented installation and testing procedures (source).

Installation Process

CCTV Inspection and Cleaning – Pre-installation video and debris removal for QA.
Wet-out Preparation – Impregnation of EcoLiner with resin; managed at in-house or satellite facilities.
Liner Inversion or Pull-In – Liner positioned inside the host pipe using air or water inversion or pull-in methods.
Curing – Liner cured using hot water, steam, or ultraviolet light as specified.
Service Lateral Reinstatement – Robotic cutting of laterals, verified with post-cure CCTV.
Post-Installation Testing and Final Inspection – Ensure structural, hydraulic, and service connection integrity.

Use Cases & Project Applications

Municipal Sewer System Rehabilitation:
Citywide gravity mains, interceptors, manhole-to-manhole lining
Service laterals via open-cut or trenchless methods
Stormwater Pipe Restoration:
Large-diameter storm drains, culverts, critical flood infrastructure (source)

Quality Assurance: Documented testing, inspections, and digital reports as part of standard project closeout.

Frequently Asked Questions (FAQ)

What is unique about Hinterland Group’s Eco

Liner system?

EcoLiner uses styrene-encapsulated liners for better environmental safety during installation, reducing odor and vapor emissions, making it ideal for sensitive sites and communities (source).

What diameters can be rehabilitated with Eco

Liner CIPP?

Hinterland Group’s process supports any diameter between 4" and 108", covering residential laterals, municipal trunk mains, and even large culvert or stormwater structures (source).

How are service laterals managed during CIPP lining?

After the liner is installed and cured, specialized robotic cutters are used to reopen each lateral connection from inside the main, with each opening documented by post-installation CCTV.

Is the system certified or installed to recognized standards?

Yes. Hinterland’s EcoLiner installations are performed to industry specs (ASTM F1216), and meet or exceed municipal acceptance criteria.

What is the typical turnaround time for mainline and lateral reinstatement?

Varies by project length and number of service connections, but most small-diameter runs can be completed within several hours, with service restored the same day for infiltrated sections. Large-diameter runs or complex projects are scheduled accordingly.

Can laterals themselves be CIPP lined?

Yes. Laterals (commonly 4"–8") can be relined with CIPP as part of the rehabilitation, providing a seamless, leak-free connection all the way from building to main (source).

What is the expected lifespan of an Eco

Liner installation?

Typical design life is 50 years, in accordance with ASTM F1216 for CIPP applications. Real-world lifespan may exceed this with proper maintenance (source).

What is required for site access?

Minimal work area at existing manholes or access structures is typically required. No major surface demolitions or road closures unless otherwise specified.

How does Hinterland ensure quality control?

Comprehensive CCTV documentation, detailed pre/post-lining assessment, lateral mapping, robotic tracking of reinstatement, and full digital reporting. All phases are completed in-house by proprietary crews (source).
