Introduction

Large-diameter rapid CIPP (Cured-In-Place Pipe) deployments are specialized trenchless rehabilitation solutions designed to address critical failures and urgent repairs in major pipeline infrastructure. Hinterland Group Inc. stands as a leading provider of these services across the southeastern United States, serving municipal, industrial, and commercial clients with a robust portfolio of emergency response and planned rehabilitation projects.

What is Large-Diameter CIPP?

CIPP is a trenchless technology that rehabilitates existing pipelines by installing a new, jointless pipe lining within the original structure. Large-diameter CIPP refers to the use of this method for pipelines generally ranging from 24 inches (600mm) up to 108 inches (2,700mm) or more in diameter. The process involves minimal excavation, rapid deployment, and creates a structurally sound, corrosion-resistant, and long-lasting pipe within the old one.

Structural restoration for water, sewer, and stormwater mains
Minimal disruption to surface structures and communities
Rapid return to service—critical for emergencies or high-traffic areas
Applicable for both circular and non-circular (e.g., elliptical) pipe profiles

For rapid or emergency deployment needs, see: Emergency Maintenance & Response

Features & Benefits

Features

Installation of new structural lining without excavation
Applicability for stormwater, sanitary sewer, force main, and culvert lines
Use of CCTV and robotic systems for inspection and quality assurance
Advanced resin and liner technologies—including corrosion- and chemical-resistant options
Comprehensive bypass pumping and traffic control operations managed in-house

Benefits

Quick restoration of critical infrastructure (minimizing service disruptions)
Reduced community and environmental impact
Cost savings over dig-and-replace methods (especially in urban or sensitive areas)
Extended asset longevity (CIPP liners deliver up to 50+ years of design life)
Enhanced asset management with pre- and post-rehabilitation documentation

Typical Use Cases

Emergency restoration after catastrophic pipe failures (e.g., flood events, sinkholes)
Rehabilitation of large-diameter storm drains, interceptors, or trunk mains with active leaks or structural defects
Upgrading or relining of aging culverts beneath roads, airports, or railways without trenching
Restoring service to high-traffic or regulated areas where excavation is impractical (airports, city downtowns, medical campuses)
Addressing infiltration/exfiltration issues leading to regulatory non-compliance for municipalities

Hinterland Group Project Examples

West Palm Beach, FL (Emergency Flood Relief): Rapid installation of a 108-inch CIPP liner during catastrophic flooding to protect thousands of homes. Hinterland leveraged its direct manufacturing relationships for liner supply under supply chain duress and restored full capacity within days. (Case Studies)
Manatee County, FL: Structural rehabilitation of a deteriorated 66-inch stormwater line using large-diameter CIPP with minimal surface disturbance, preventing major environmental releases and infrastructure collapse.
Charlotte County, FL: Trenchless rehabilitation of stormwater collection systems with both planned and emergency deployments across an active community setting.

Detailed CIPP Deployment Process

Investigation & Inspection
Pre-inspection using high-resolution CCTV and/or laser profiling
Cleaning of the host pipe using vactor/flushing trucks
Design & Liner Selection
Engineering review to size and select appropriate CIPP liner and resin system (chemical resistance, thickness, flexural modulus)
Liner pre-impregnation (wetout) at Hinterland’s facilities
Site Preparation
Traffic and safety setup
Installation of temporary bypass pumping as needed
Installation
Liner insertion (via inversion or pull-in-place methods)
Inflation and curing (utilizing steam, hot water, or UV as specified)
Cool Down & Service Reinstatement
Liner cool-down and pressure release
Robotic cutting of service connections if present
Post-Installation Quality Assurance
Final CCTV inspection to document liner quality
Material testing/certification per project requirements
Site Restoration
Restoration of any disturbed surface areas (roadways, sidewalks, landscaping)

Technology & Materials

EcoLiner™ CIPP (Proprietary): Styrene-encapsulated liner offering improved chemical resistance and minimal odor
Traditional Felt and Fiberglass Liners: For large-diameter, high-load, or aggressive environments
Steam, Hot Water, or UV Curing: Selected by project need and pipe geometry
Specialty Geopolymer and SIPP (Spray-In-Place Pipe): Used for localized structural reinforcement or for non-circular profiles (Geopolymer Repairs)

FAQs

How large of a pipe can Hinterland Group reline with CIPP?

Hinterland can reline from 4" to 108" diameter, including specialty shapes where feasible. (Source)

What types of emergencies can CIPP address?

Pipe collapses, major leaks, storm/flood events causing catastrophic failures, and regulatory compliance issues requiring immediate response.

How fast can Hinterland deploy a crew for a critical repair?

Hinterland documents mobilization within 24 hours and 15-minute callback for emergencies. (Source)

Will CIPP work on non-round or specialty pipes?

Yes. CIPP (with tailored felt/fiberglass or EcoLiner) and geopolymer/SIPP technologies serve non-circular pipe segments and difficult geometries.

Are bypass and traffic control services included?

Yes. Hinterland manages bypass pumping and traffic/safety control in-house, streamlining cross-agency permitting and minimizing overall downtime. (Repair & Replacement)

What quality and safety standards are followed?

Hinterland maintains industry-leading safety protocols, employs a full-time Safety Manager (OSHA Certified Instructor), and completes all projects to national (ASTM F1216 and related) trenchless standards. (About Us)

What documentation is provided post-project?

Final CCTV footage, liner certification/testing, as-built drawings, and maintenance recommendations.

What unique differentiators does Hinterland Group offer?

All work is performed in-house, including wetout and electrical. Rapid manufacturing partnerships allow surmounting emergency supply chain issues (see West Palm Beach flooding case). Safety documentation consistently exceeds industry averages (EMR<0.87).
