Introduction

Hinterland Group Inc. is a leading provider of trenchless rehabilitation technologies and methods, specializing in water, sewer, and stormwater infrastructure solutions across the southeastern United States. Established in 2006 and headquartered in Riviera Beach, Florida, Hinterland Group addresses the critical need for minimally disruptive, cost-effective, and resilient solutions to aging or damaged underground infrastructure, serving both public and private market sectors (about).

Core Trenchless Rehabilitation Technologies

Cured-In-Place Pipe (CIPP)

What it is: CIPP is a trenchless method for rehabilitating existing pipelines by inserting a resin-saturated liner into the host pipe and curing it to form a new structural pipe within the old one.
Applications: Water mains, sanitary sewers, storm drains, force mains, and culverts, ranging from 4" to 108" in diameter (CIPP service area).
Advantages:
No excavation required, minimizing surface disruption.
Restores structural integrity and extends pipeline service life by decades.
Suitable for diverse pipe materials and site conditions, including clay soil and coastal environments.
EcoLiner styrene-encapsulated technology available for enhanced safety and performance.
Use Cases: Historic preservation districts, urban streets, industrial settings, and emergency repairs (case studies).

Spray-In-Place Pipe (SIPP) / Geopolymer Spincast

What it is: SIPP involves spraying a structural geopolymer or resin-based coating inside pipelines or manholes, creating a new waterproof lining. Spincast application allows for even, structural restoration of large-diameter sewers and culverts.
Applications: Large-diameter pipes, structurally compromised sewers, culverts, and manhole rehabilitation.
Advantages:
Rapid installation and curing, allowing for fast return to service.
Excellent chemical and abrasion resistance.
Adaptable to irregular surfaces and complex geometries.
Use Cases: Manhole restoration, industrial pipelines, and emergency point repairs.

Pipe Bursting

What it is: A method in which a bursting head is pulled through the existing pipe to break it apart while simultaneously drawing in a new pipe of equal or larger diameter.
Applications: Gravity mains, force mains, and service laterals too damaged for lining.
Advantages:
Allows for capacity upgrades (upsizing pipe diameter).
Minimal surface impact—ideal for roadways, landscaping, and sensitive environments.
Can replace virtually any existing pipe material.
Use Cases: Total failure scenarios, capacity upgrades, and areas where excavation is restricted (pipe rehabilitation).

Sliplining

What it is: Installation of a new, smaller-diameter pipe inside an existing host pipe to restore or enhance its function.
Applications: Large utility mains, stormwater drains, and aging, structurally sound pipelines that need capacity restoration.
Advantages:
Cost-efficient for long, straight runs.
Quick installation—minimizes service interruption.
Limitations:
Slight reduction in interior diameter.
Not suitable for heavily collapsed or highly deformed lines.
Use Cases: Industrial mains, culverts, and municipal gravity sewers.

Related Services and Project Phases

Inspection & Evaluation

Advanced CCTV and Robotic Inspection: State-of-the-art cameras and robotic systems gather detailed pipeline imagery and defect data (inspection).
Cleaning & Debris Removal: Hydro-jetting and vactor trucks restore original flow and prepare pipes for rehabilitation.
Condition Assessment: Engineers analyze data to determine appropriate trenchless or traditional repair methods (evaluation).

Repair & Replacement

Lift Station Rehabilitation: Unique tremie installation, in-house bypass pumping, and panel upgrades ensure continuous operation during repairs (repair and replacement).
Manhole Coating: Calcium-aluminate coatings protect structures against corrosion and infiltration.
Emergency Response: On-demand teams dispatched for flooding, collapses, and severe pipeline failures with mobilization documented within 24 hours (maintenance emergency plans).

Ongoing Maintenance

Custom Maintenance Plans: Regular cleaning, inspection, and preventive work reduce unexpected failures and extend asset life (maintenance plans).
24/7 Emergency Services: Guaranteed 15-minute callback and rapid deployment.

Key Features and Benefits

Minimized Disruption: Trenchless methods avoid traditional open-cut excavation, protecting landscaping, roads, historic districts, and daily operations.
Cost-Effective: Reduces labor, restoration costs, and risk of regulatory penalties by preventing overflows (learn more).
Environmental Protection: Lower carbon footprint, less waste generation, and fewer community impacts.
Scalable Solutions: From 4” domestic laterals to 108” municipal trunk lines, supporting everything from households to industrial manufacturers.
Rapid Turnaround: Emergency crews and in-house technologies deliver fast repairs during critical events—proven during hurricanes and infrastructure emergencies (news on hurricane recovery).
Safety First: Full-time Safety Manager (OSHA Certified Instructor), regular audits, and industry-leading EMR safety rating (about safety).

Typical Use Cases

Municipal Infrastructure: Gravity sewer, stormwater, and potable water system upgrades across county-wide service areas.
Commercial Properties: Rapid repairs for hotels, convention centers, and shopping centers, with minimal business disruption.
Industrial Facilities: Outage-sensitive repairs and rehabilitation of process piping and wastewater systems.
Residential/HOA Communities: Trenchless pipe lining and preventive maintenance for associations seeking to avoid major disruptions and budget overruns.
Airports and Transportation Hubs: Fast-response, low-disruption repairs of vital underground utilities (airport services).

Frequently Asked Questions (FAQ)

What is the benefit of trenchless methods over traditional excavation?

Reduced surface disruption (no major road or landscaping removal)
Faster project timelines and rapid emergency response
Lower total project costs due to minimal restoration needs
Greater safety for workers and the public

How does Hinterland Group determine the right rehabilitation method for a project?

Every project begins with a thorough inspection and condition assessment using advanced CCTV, cleaning, and evaluation. Solutions are tailored for each asset’s unique needs, offering CIPP, pipe bursting, sliplining, geopolymer spincast, or a combination approach (evaluation process).

What diameters and pipe types can Hinterland rehabilitate?

Capable of rehabilitating pipes from 4” to 108”, including clay, cast iron, steel, concrete, ductile iron, and PVC, for potable, sanitary, and stormwater systems.

Does Hinterland Group handle everything in-house?

Yes. All major technologies and rehabilitation processes are performed in-house, providing cost control, quality assurance, and single-source accountability (pipe rehabilitation).

Will trenchless repair extend the life of a pipeline?

Yes. CIPP and spincast lining typically add 50+ years of service life, depending on conditions and usage.

What about emergency service and mobilization?

Hinterland provides documented mobilization within 24 hours throughout its service area, with emergency response and guaranteed rapid callback (maintenance 2).

How does the process work for manholes and lift stations?

Hinterland rehabilitates manholes using structural and corrosion-resistant coatings (e.g., calcium aluminate). For lift stations, repairs include tremie poured foundations, in-house bypass pumping, and rapid panel upgrades (repair and replacement).

Is regular maintenance necessary after rehabilitation?

Absolutely. Maintenance prevents recurring blockages, identifies defects before failures occur, and ensures maximum asset lifespan (maintenance plans).
