Introduction


Advanced Trenchless Solutions for Critical Infrastructure

Large-diameter pipelines are the backbone of municipal, industrial, and commercial infrastructure. When these systems begin to deteriorate due to corrosion, cracking, infiltration, or structural wear, the consequences can be severe. Repercussions include service interruptions, environmental hazards, and costly emergency repairs.

At Advanced Pipe Repair, we specialize in large-diameter pipeline rehabilitation using proven trenchless technologies that restore structural integrity without disruptive excavation. Whether you manage a municipal sewer system, stormwater conveyance network, industrial process line, or transportation drainage system, our team delivers engineered solutions designed to extend asset life and minimize downtime.

What Is Large-Diameter Pipeline Rehabilitation?


Large-diameter pipeline rehabilitation refers to restoring pipes, typically 36 inches and greater in diameter, from the inside rather than replacing them entirely. Instead of digging up roadways, facilities, or landscapes, trenchless rehabilitation renews the existing pipe structure using advanced lining and coating systems.

This approach allows infrastructure owners to:

  • Reinforce structural stability
  • Eliminate leaks and infiltration
  • Improve hydraulic flow
  • Prevent further corrosion
  • Extend service life by decades

Rehabilitation is often the most cost-effective and least disruptive alternative to traditional dig-and-replace methods, particularly for critical systems that cannot afford extended shutdowns.

Our Trenchless Rehabilitation Solutions


Advanced Pipe Repair offers specialized trenchless methods specifically suited for large-diameter infrastructure. These solutions are engineered to address complex structural deterioration, corrosion, and infiltration issues without the need for disruptive excavation.

By combining advanced materials, precision application techniques, and experienced project oversight, we deliver rehabilitation systems designed to restore strength, improve performance, and extend the lifespan of critical pipeline assets.

Below are our most common large-diameter pipeline rehabilitation solutions in more detail.

Spray-in-Place Pipe Repair (SIPP)


Spray-in-Place Pipe Repair (SIPP) is a high-performance rehabilitation method designed for large pipelines, including culverts, storm drains, and sanitary sewer systems.

Using robotic application equipment, we apply a high-strength cementitious or polymer coating directly to the interior surface of the pipe. This creates a seamless, corrosion-resistant lining that restores structural integrity and protects against future deterioration.

SIPP is especially effective for very large diameters, including pipelines up to 120 inches. It provides:

  • Uniform interior coverage
  • Structural reinforcement
  • Improved flow characteristics
  • Rapid cure times
  • Minimal surface disruption

Because the system is applied internally through existing access points, excavation is not required. This allows infrastructure to remain operational with minimal interruption.

Cured-In-Place Pipe (CIPP) Lining


Cured-In-Place Pipe (CIPP) lining is another core solution we use for large-diameter rehabilitation projects.

In this process, a resin-saturated flexible liner is inserted into the existing pipeline and cured in place using heat, steam, or UV light. Once cured, the liner forms a durable, jointless pipe-within-a-pipe that seals cracks, eliminates leaks, and restores structural strength.

CIPP is ideal for:

  • Large sewer mains
  • Stormwater systems
  • Industrial pipelines
  • Aging municipal infrastructure

The finished product is watertight, corrosion-resistant, and designed for long-term performance under demanding service conditions.

Our Proven Rehabilitation Process


Every large-diameter rehabilitation project begins with careful evaluation and engineering.

1. Robotic CCTV Inspection & Assessment
We perform high-resolution internal video inspections to assess pipe condition. This allows us to identify cracks, joint offsets, corrosion, infiltration points, and structural deficiencies. Accurate diagnostics ensure the right rehabilitation method is selected.

2. Cleaning & Surface Preparation
Before installation, pipelines are thoroughly cleaned using hydro-jetting and specialized descaling equipment. Removing debris and buildup ensures proper adhesion and optimal performance of the rehabilitation system.

3. Engineered Rehabilitation Design
Our team develops a tailored rehabilitation plan based on pipe diameter, material, condition, and service requirements. Structural considerations and material selection are carefully evaluated to ensure long-term success.

4. Trenchless Installation
Using existing manholes or access points, we install the selected system without major excavation. Controlled curing processes ensure proper bonding and structural integrity.

5. Final Inspection & Quality Assurance
After installation, we conduct a post-rehabilitation CCTV inspection to verify complete coverage and performance. Detailed documentation provides confidence that the pipeline has been successfully restored.

Why Trenchless Rehabilitation Is the Smarter Choice


Traditional pipe replacement requires extensive excavation, traffic control, environmental disturbance, and prolonged service interruptions. In contrast, trenchless rehabilitation offers significant advantages:

  • No large-scale excavation
  • Reduced traffic and site disruption
  • Lower total project costs
  • Faster completion timelines
  • Environmentally responsible solution
  • Extended infrastructure lifespan

For municipalities, facility managers, and infrastructure owners, trenchless renewal preserves both budgets and operations.

Frequently Asked Questions


What qualifies as a large-diameter pipeline?

Typically, pipelines 36 inches and larger are considered large-diameter systems.

How long does trenchless rehabilitation last?

When properly designed and installed, SIPP and CIPP systems can extend pipeline life by decades.

Can the pipeline remain operational during rehabilitation?

In many cases, yes. Our trenchless methods are designed to minimize downtime.

How long does a project take?

Project timelines vary depending on diameter, length, and condition, but trenchless methods are significantly faster than traditional replacement.
