CIPP Technology Overview

Cured-In-Place Pipe (CIPP) is a trenchless pipeline rehabilitation method in which a resin-saturated felt or fiberglass liner is installed and cured within an existing pipe. The process forms a jointless, corrosion-resistant, and structurally sound new pipe inside the old one, minimizing the need for excavation and reducing surface and environmental disruption.

• Trenchless: No need for open-trench excavation for the majority of pipe repairs

• Structural Renewal: Adds new load-bearing structure to deteriorated pipes

• Versatile: Can rehabilitate pipes of various shapes, sizes, and materials (concrete, clay, cast iron, PVC, etc.)

• Quick Return to Service: Curing and reinstatement is rapid, minimizing downtime (Source)

Eco

Liner Styrene-Encapsulated Liners (4"–108")

Product Description

EcoLiner is Hinterland Group’s advanced CIPP liner technology for diameters from 4 inches (100mm) up to 108 inches (2740mm). The EcoLiner system uses a styrene-encapsulated resin matrix which provides enhanced chemical resistance, environmental control, and installation performance compared to traditional CIPP resins.

Features

• Diameter Range: 4" to 108" (100 mm – 2740 mm)

• Styrene-Encapsulated Resin: Controls emissions and odors during cure

• Structural Design: Engineered for both pressure and gravity pipelines

• Corrosion & Chemical Resistance: Suitable for sanitary, stormwater, and industrial applications

• Minimally Invasive: Ideal for sensitive, urban, or environmentally critical locations

• Customizable Wall Thickness: Designed per project structural and hydraulic requirements (Source)

• Rapid Installation and Curing: Helps minimize service interruption

Benefits

• Environmental Safety: The encapsulation prevents styrene migration, reducing VOCs and odors

• Regulatory Compliance: Meets or exceeds industry and local utility standards

• Longevity: Extends useful life of pipelines by 50+ years

• Minimal Disruption: Installation can be completed with little or no digging, reducing impacts to communities, businesses, and natural habitats

• Versatility: Available for pipes of various materials, shapes (round, elliptical, box), and installation conditions (infrastructure, industrial plants, airports, etc.)

• Cost Efficiency: Typically less expensive and faster than traditional open-cut replacement

Frequently Asked Questions (FAQ)

What diameters can Hinterland Group line with Eco

Liner?

• EcoLiner liners are available for 4-inch through 108-inch diameter pipelines. (Source)

Where is Eco

Liner best used?

• EcoLiner is ideal for sanitary and storm sewers, culverts, industrial lines, and any infrastructure requiring enhanced chemical resistance or emission control – especially in urban, occupied, or environmentally critical settings.

Is Eco

Liner CIPP suitable for potable water?

• Potable water use requires project-specific review. Most applications are for non-potable lines. Contact Hinterland Group for details (Contact).

What is the installation downtime?

• Most lines can be rehabilitated and returned to service in less than a day, depending on length and diameter, minimizing community/business impact.

Is there open trenching involved?

• No open trench is needed except for limited access points; work is typically performed from manholes or small pits.

How is the structure verified after lining?

• All projects include pre- and post-installation CCTV inspection, with full documentation supplied (QA/QC).

Is Eco

Liner CIPP more environmentally friendly?

• Yes; styrene encapsulation reduces airborne VOCs and environmental exposure of chemical components during installation, making it suitable for regulated environments.
