Trenchless Pipe Rehabilitation Solutions (SIPP·CIPP)
Trenchless SIPP·CIPP Lining for Pipeline Rehabilitation
Restores the performance of old pipes by forming a seamless lining inside them using trenchless robotic technology. Unmanned installation is possible for pipe diameters from 30 to 3000mm and lengths up to 150m.
Why Rehabilitate Aging Pipes Instead of Replacing Them?
Replacing pipes requires excavation, but rehabilitation preserves existing pipes without excavation.
Since excavation is not required for pipe replacement (trenchless method), there is no need for surrounding area control during construction, and it is highly efficient socially, economically, and time-wise compared to traditional replacement methods. Road closures are avoided, and the construction period and costs for backfilling and pavement restoration are eliminated.
What is Trenchless Pipe Rehabilitation?
It is a method that forms a special polyurea lining inside the pipe, creating the effect of a new pipe.
Despite polyurea being a high-performance advanced material with excellent waterproofing, hardness, tensile strength, and corrosion resistance, in Korea, it is primarily used as a flooring material and waterproofing agent for buildings. However, in the U.S. and Europe, it is already widely used for industrial special coatings, particularly for internal and external lining applications aimed at protecting, strengthening, and restoring aging and corroded pipes in water and sewage facilities.
HIGHCOATIC utilizes special raw materials for pipe lining, not general-purpose polyurea used for flooring, providing not only corrosion-preventive coating for new pipes but also pipe restoration technology that utilizes existing aging pipes.
Why is a lining thickness of 19-51mm important?
Unlike thin coatings of 1-2mm, it creates a structural body inside the pipe, effectively creating a new pipe.
The most significant feature of HIGHCOATIC's lining technology is that it allows for lining thicknesses of 19mm to 51mm, unlike typical thin coatings of 1-2mm. This goes beyond simple waterproofing and corrosion prevention, as it forms a structural body inside the pipe, effectively creating a new pipe.
How is installation performed without human entry into the pipe?
Specially designed robots are remotely controlled from outside the pipe to perform unmanned internal lining.
HIGHCOATIC's pipe lining is installed without direct human entry, as it is remotely controlled by specially designed robots from outside, ensuring worker safety and achieving more uniform performance.

What are the related patents?
Three patents related to pipe lining and one for flexible leak mold, totaling four applications.
- Polyurea Resin Composition for Lining for Corrosion Prevention and Rehabilitation of Aging Pipes
- Polymer Spray Lining Method for Trenchless Pipeline Rehabilitation
- High-Pressure Automatic Spraying Device for Polyurea Lining Inside Pipes
- Pipe Maintenance Technology — Flexible Leak Mold
What is Flexible Leak Mold technology?
It is a patented technology that seals leakage points with molding, without pipe replacement or welding.
HIGHCOATIC's patented Flexible Leak Mold technology concerns a method for sealing leaks in pipes requiring high corrosion and acid resistance, such as those in semiconductor, pharmaceutical, and petrochemical industries, without pipe replacement or welding. It involves creating a mold using a flexible sheet, fastening it to the leaking pipe section, and then injecting and curing a special corrosion and acid-resistant polyurea into the mold to repair the leak. This technology is applicable even in situations where replacement or conventional repair methods are impossible due to the diverse shapes of pipes and extremely confined spaces characteristic of semiconductor facilities.
What are some international installation cases?
Large-diameter pipeline rehabilitation has been performed in Canada, the U.S., Australia, and Saudi Arabia.

What is trenchless pipe rehabilitation?
This is a method for rehabilitating deteriorated pipes by forming a lining inside them without excavation. While pipe replacement necessitates excavation, the trenchless method utilizes the existing pipes, eliminating the need for site control during construction, and proving significantly more efficient in social, economic, and temporal aspects.
What is the maximum pipe diameter that can be rehabilitated?
Pipes ranging from 4 inches in diameter up to 3 meters can be lined autonomously. Since the 360 Ringtech Robotics System allows for remote control from outside, personnel do not need to enter the pipe, ensuring worker safety and more uniform performance.
What is the lining thickness?
19mm to 51mm. Unlike typical coatings that are 1-2mm thick, this thickness forms a structural layer inside the pipe, effectively creating a new pipe rather than merely providing waterproofing or corrosion protection.
What are the differences between SIPP, CIPP, and PVC lining methods?
CIPP is a cured-in-place method for large pipes, SIPP is a spray-in-place method for small pipes, and PVC lining involves adhering an internal sheet. While most companies specialize in only one rehabilitation method, HIGHCOATIC can handle all three, allowing us to select the optimal method tailored to specific site conditions.
What is polyurea?
It is an elastic coating material developed by Texaco in the early 1980s in the United States. It boasts an elongation of over 400%, concrete adhesion of over 3.0 N/mm², and heat resistance of 120°C for gases and 85°C for liquids. It is widely used for waterproofing, abrasion resistance, chemical resistance, and corrosion protection.
Do you hold environmental certifications?
All products have received eco-friendly certification for use in drinking water and food facilities. They contain 0% volatile organic compounds (VOCs) and have completed certification for use in drinking water and food facilities from relevant authorities in the US, Singapore, Canada, China, and other countries. Additionally, they hold ASTM E84 Class 1 flame spread certification.
What is HIGHCOATIC's relationship with NUKOTE?
