(About Us)

Core Trenchless Rehabilitation Methods

Cured-In-Place Pipe (CIPP)

• Overview: CIPP is a trenchless technology that lines existing pipes with a resin-saturated felt tube which is then cured to form a new, jointless pipe within the old structure. No digging is required except for access points (CIPP Georgia).

• Applications: Wastewater, sewer, stormwater, and potable water mains.

• Advantages:

• Minimally invasive—reduces surface and community disruption

• Extends pipe life by decades

• Suitable for pipes from 4” up to 108” diameter (EcoLiner technology)

• Result: Restores structural integrity, prevents infiltration/exfiltration, and improves flow characteristics.

• Environmental Impact: Significantly reduces carbon footprint compared to open-cut replacements (Maintenance Plans).

Spray Applied Geopolymer (SIPP/Geopolymer Spincast)

• Overview: Spray-in-place pipe (SIPP) or geopolymer lining involves applying a high-strength, corrosion-resistant geopolymer layer to the interior of failing pipes or manholes (Services).

• Best For: Large-diameter pipelines, manholes, stormwater culverts, and structures with structural deterioration or chemical attack.

• Key Benefits:

• Extremely fast curing for rapid return to service

• Restores original structural capacity with seamless layer

• Exceptional chemical, abrasion, and corrosion resistance

• Use Cases: Emergency infrastructure repairs, long-term manhole/culvert protection, and restoring lost structural integrity.

Pipe Bursting

• Overview: Allows complete replacement of failing/broken pipelines by fragmenting the old pipe and simultaneously pulling in a new, often larger, pipe using a bursting head.

• Use Cases:

• Severely collapsed or undersized pipelines

• Areas where pipe capacity upgrade is required

• Advantages:

• Installs new pipe in place of the old path

• Minimal surface disruption, ideal for urban or developed areas

Sliplining

• Overview: Involves inserting a new, slightly smaller pipe liner into an existing host pipe, then grouting the annular space (Pipe Rehabilitation).

• Applications:

• Reinforcing structurally deficient pipelines

• Increasing hydraulic capacity

• Benefit: Quick, simple, and preserves existing infrastructure with little impact above ground.

Trenchless Manhole Rehabilitation & Coating

• Techniques:

• Geopolymer or calcium aluminate coatings (e.g., Refratta process)

• Epoxy or polymeric structural liners

• Purpose: Stops infiltration, reinforces structural components, and provides chemical resistance in corrosive sewer and storm environments (Repair & Replacement).

• Result: Sealed, extended service life for manholes with minimal disturbance.

PRIME Approach—Comprehensive Infrastructure Services

Hinterland's PRIME system encompasses:

1. Pipeline Rehabilitation (CIPP, SIPP, bursting, sliplining)

2. Repair & Replacement (lift stations, gravity mains, laterals)

3. Inspection (CCTV, vactor cleaning, robotic camera evaluation)

4. Maintenance (preventive cleaning, scheduled repairs, 24/7 emergency)

5. Evaluation & Assessment (risk, lifecycle, planning) (PRIME Services)

Materials Utilized

• EcoLiner (CIPP): Innovative, styrene-encapsulated felt/fiber composites with environment-friendly resins for durability and superior installation outcomes.

• High-Strength Geopolymers: Used for SIPP and spincast linings, providing chemical and structural resilience (ideal for sewer and storm applications).

• Calcium Aluminate and Epoxy Systems: Advanced coatings for manhole and lift station rehabilitation, combating hydrogen sulfide and corrosive conditions.

Applications & Use Cases

• Municipal Sewer and Water Line Rehabilitation: Extending life and compliance of city systems with minimal resident impact (Case Studies).

• Stormwater and Flood Control: Rapid repair and resilience upgrades after major storm events (ex: post-hurricane infrastructure recovery).

• Industrial/Manufacturing Sites: Minimizing production downtime by providing quick pipe, process piping, or lift station repairs without open excavation (Industrial Services).

• Commercial and Property Management: Scheduled maintenance, emergency flood response, and capacity upgrades for malls, airports, stadiums, etc. (Commercial, Property Management Firms).

• HOAs & Communities: Preventive maintenance programs, prioritizing repairs for property value and resident satisfaction (Homeowners & POA).

Unique Value Proposition & Differentiators

• All Technologies In-House: No subcontracting—direct quality control, best-value proposal per client's needs, efficient project execution (Pipe Rehabilitation).

• Industry-Leading Emergency Response: 24/7 availability with guaranteed 15-minute callbacks. Documented mobilization within 24 hours throughout the Southeast (Maintenance-2).

• Advanced Equipment: High-res CCTV, vactors, specialized CIPP curing and wetout facilities in both Florida and North Carolina (CIPP North Carolina).

• Safety Commitment: Projects led by OSHA-certified managers; rigorous safety culture and practices; industry-low EMR rating.

• Custom Maintenance Plans: Annual, ongoing preventive programs to extend asset life and lower lifecycle costs (Maintenance Plans).
