Sewer Rehabilitation Using CIPP Lining for City Development

Applied Felts - CIPP Lining Manufacturer

Sewer rehabilitation at the city development level is an enormous undertaking. Many things can impact the structural integrity of sewage systems and their intricate networks of pipes. Traditional solutions require invasive installation, community complications, plumbing downtime, and high costs.

Cured-in-place pipe (CIPP) lining technology exceeds all other methods by providing a more affordable sewer and pipe repair solution with a minimally invasive installation that increases flow capacity and performance metrics. Once installed, the versatile solution can seal seams, strengthen joints, repair corrosion, eliminate root intrusion, and support the host pipe without any complex digging requirements. 

How a Cured-in-Place Pipe (CIPP) Liner Works

CIPP Composition and Process
Cured-in-place pipe (CIPP) products repair leaking, cracked, and broken sewer pipes through an advanced internal insertion method that eliminates digging or drilling underground. CIPP liners include two critical layers: the resin-soaked felt tube and the impenetrable polyurethane exterior coating.

The installation involves inserting (or “shooting”) and inverting the flexible liner into the host pipe so the resin-soaked felt adheres to the host pipe. The CIPP liner results in a pipe within a pipe perfectly conformed to the existing diameter.

The UV or heat-curing process seals the resin-soaked felt to the compromised pipe lining to create a durable, leak-proof inner tube. Because of the simple installation method, cured-in-place pipe solutions provide complete repair, no matter the project complexities or challenges.


A Cost-effective Solution for Widespread Pipeline Rehabilitation

CIPP Liner Repairs
CIPP liners are the future of city development. As cities plan to expand, they must consider how the existing storm sewers and pipes will handle the new infrastructure. CIPP lining technology is the affordable, efficient, and environmentally friendly answer to any sewer rehabilitation project.

CIPP liners can repair the following:

  • Pressurized systems
  • Potable water
  • Gravity sewer lines
  • And more

Customers and communities worldwide rely on CIPP solutions daily because the equipment offers rapid and effective long-term results for fewer resources.


CIPP Liners vs. Traditional Pipeline Rehabilitation Methods

Sewer damage can cause negative ripple effects throughout a community. Cracks, leaks, and malfunctions within a pipe and sewer system lead to long-term environmental hazards and public health concerns. When cities develop and expand, sewage complications happen more frequently as the outdated system cannot meet modern demands.

Open-cut repairs, the traditional method, involve digging, cutting out the damaged area, and replacing it. Such jobs put contractors at high risk by dealing with hazardous materials, creating general safety concerns. Open-cut repairs also take enormous amounts of time, training, equipment, and money, which many infrastructures cannot accommodate.

The ramifications of closing a single street to replace one cracked pipe can include disrupted traffic patterns, closed business operations, upset customers, and more. The problems only amplify in hard-to-reach or hard-to-access locations, like under bridges or historical sites.

Pipe liners allow cities to resolve sewer concerns without complex, expensive repairs. The process offers immediate results that protect the health and safety of everyone involved.

Reasons to choose CIPP lining over repair cutters include the following:

  • Improved safety: The resin-sealing installation process within the tubes prevents contractors from coming in contact with hazardous materials, making the process safer.
  • Reduced costs: CIPP solutions typically cost 20% to 40% less than open-cut repairs, making them the preferred choice for many business, residential, and citywide applications.
  • Increased durability: Traditional repairs cut open the pipe system, which often causes hazardous materials to leak through the cracks, infiltrating the city’s groundwater. CIPP repairs use a jointless tube that prevents leaks and can last up to 100 years.
  • Versatile applications: CIPP liner solutions can repair many types of damages, including cracks, leaks, corrosion, deterioration, root intrusion, and more, across various pipe types and diameter sizes.

Our Manufacturing Process for Host Pipe Liners

As a 100% vertically integrated manufacturer, we guarantee that every process happens directly under our roof. We use a 28-stage testing system to maintain impeccable control and precision from the supplies we start with and the tools we use to the final tubes.

Our liner manufacturing system includes the following steps:

  • Inspection: Before production, we test all tools, equipment, and materials from suppliers, including polyester fibers and polyurethane granules, to ensure that everything meets our quality standards.
  • Production: Our five-stage pipe lining production process includes tests that measure felt thickness, density, fiber evenness, weldability, and strength.
  • Coating: We use a single-pass method to coat the felt and locate any pinholes that could cause issues within pipes. During the coating application, we test uniformity, weight distribution, and mass.
  • Testing: After coating, we test samples of each roll across nine characteristics for optimal quality. Completed items go through a final stage of seven tests before meeting our expectations.
