Depending on the degree of deterioration in the existing pipe and the extent of structural repair and rehabilitation, the CFRP liners can be designed as follows:
  • Stand-alone system:
    • CFRP Stand-Alone system is required when the existing host pipe is severely deteriorated and does not have the required capacity to resist the applied external and/or the internal loads.
    • The CFRP system is designed to fully support the following loads:
      • External hydrostatic pressure
      • Soil fill and any other surcharge loads
      • The internal pressure
      • The internal vacuum pressure (if any)
  • Composite system with the existing pipe:
    • CFRP system can be designed as a composite system with the existing host pipe in cases where the host pipe is partially deteriorated.
    • The host pipe and the CFRP system share the applied external and internal pressure.
    • Composite design of CFRP requires a smaller number of CFRP plies and leads to a more economical design. Usually two or three layers of CFRP is adequate to resist the applied loads.
  • Protective coat:
    • The thickness of the CFRP is determined based on the project’s service life and the severity of the aggressive environment inside the pipe. Generally, the number of CFRP plies does not exceed two.
    • Protection of Waste Water Facilities against aggressive chemicals.
    • CFRP or Glass Fibre Reinforced Polymers (GFRP) liners can be applied to provide a protection layer against aggressive environmental conditions.
    • The host pipe is assumed to be able to fully resist the applied external and internal loads with no load sharing with the CFRP liner.

Infrastructure includes all Public Work systems that every City needs to function properly, such as water & waste water transmission lines, treatment plants, roads, tunnels, railways, bridges, energy plants, telecommunication towers, and many more. These structures require large capital investment and various maintenance programs that can be very costly in the long-term. In most cases, very tough decisions have to be made when renewing/rehabilitating infrastructure while keeping it in service.

TCI offers a wide range of repair and environmental protection materials that can save municipalities budgets at the time of construction and as well as the operational phases of infrastructure projects. TCI’s high-strength products offer strong environmental protection, and long-service life and allows engineers to select the right material for the right goal.

Whether you are repairing an existing bridge, a silo structure, renewing existing pipeline, upgrading water or wastewater plant, contact TCI to connect you with our professional engineers to discuss your needs and get advice and help you to select the right and most suitable product for your project.

Water & Wastewater Pipes

Water transmission pipes & Wastewater trunks are major arteries in our Cities. Beside the tremendous capital cost to construct water & wastewater piping systems, maintaining the functionality of these systems at all operational & environmental conditions is very costly, and sometimes, it’s difficult to keep these systems in service while doing the repair work. Hence, proper initial design and protection measures allows these systems to stay in-service for a long time.

TCI has developed special structural repair and environmental protection products that allow:

  • Protection of pipes from harsh environments usually found in sewer headspace.
  • Restore the structural capacity of deteriorated pipes through trenchless technology application.
  • Complete renewal of fully deteriorated pipes through trenchless technology application.

TCI offers products for protective liners as well as products for structural repair and complete renewal of existing pipes, culverts, and sewer trunks using Carbon-Fibre Reinforced Polymers (CFRP) and structural liners. 

Extremely high bond strength to existing moist/damp concrete surfaces allows TCI coating system to stay adhered to the substrates under high negative hydrostatic pressure. Our products were proved to resist at least 14 bars of negative hydrostatic pressure with at least a safety factor of 2.

Consult our professional engineers to get advice on the most suitable products for your needs. Get more detailed information about TCI ProTecStrong SPL and TCI CarbonStrong SPL.

Manholes & Chambers

Manholes & chambers are auxiliary elements in the water and wastewater systems that allow access and maintenance of underground structures. Chambers usually accommodate very expensive equipment. Therefore, proper design and protection of new manholes and chambers can extend the service life of these structures and lower the operation cost on the long run.

Existing manholes and chambers, especially those built decades ago, may exhibit severe deterioration and may need rehabilitation, upgrade, repair, or sometimes complete renewal. TCI products are formulated to provide the best protection barrier as well as structural strength to your concrete (precast or cast-in-place), brick, or masonry manholes & chambers.

Damp substrate or leaking cracks in existing manholes or chambers are not obstacles for proper application of TCI products. TCI has the right product for you. Extremely high bond strength to existing concrete surfaces is one of our high-end goals, allowing TCI products to be applied on damp/moist substrates.

Whether you have a new project for manholes & chambers, or repairing/rehabilitating existing ones, consult TCI technicians to discuss what products are most suitable for your needs.

Reservoirs & Wet Wells

Concrete reservoirs & wet wells may exhibit deterioration problems due to corrosion of steel rebar, embedded in the concrete. Waterproofing of concrete surfaces in direct contact with water will help extend the service life of your reservoir.

Waterproofing of internal concrete surfaces in reservoirs and wet wells provides damp-proof barrier on the other side of the walls (in dry wells and equipment rooms)

TCI ProTecStrong SPL as well as TCI CarbonStrong SPL are NSF 61 certified and approved for potable water applications, offering one of the best options for the rehabilitation, repair, and strengthening of concrete surfaces in potable water structures such as reservoirs and wet wells.

Experience the high strength, high tensile modulus, and high chemical protection of your concrete surfaces by using TCI products.

Extremely high bond strength to existing concrete surfaces ensures permanent adhesion of our coating system under the effect of high negative hydrostatic pressure.

Consult TCI technicians to discuss what products are most suitable for your needs.

Settling Tanks

Settling tanks (Clarifiers) are major parts of wastewater treatment plants, in which suspended particles in the wastewater are allowed to settle and providing a level of purification. The accumulated sludge at the bottom of the tanks is periodically removed.

Concrete surfaces in settling tank are exposed to harsh conditions from the biological and chemical components in the wastewater. Chemical protection of concrete in settling tanks is one of our major goals in extending the service life of your wastewater treatment plant.

Call TCI and ask about ProTecStrong SPL, our high-end product which passed a comprehensive testing program and proved to be one of the best protective liner in the industry. Our products can be used to protect concrete surfaces in the construction phase of your plant as well as in the rehabilitation/upgrade phase of existing plants.

Damp or moist concrete surfaces, leaking cracks, deteriorated concrete, corrosion of steel bars, high negative hydrostatic pressure, and many more unfavorable conditions ARE NOT a problem in applying TCI products.

Consult TCI technicians to discuss what products are most suitable for your needs.

Aeration Tanks

Aeration tanks in a wastewater treatment plant are used to clear water in a stage known as secondary treatment process, where high levels of oxygen are introduced by pumping air into the treated water mass. The concrete surfaces in aeration tanks, if not properly protected, may suffer from bio-deterioration.  

Bio-deterioration can lead to damages in the concrete surfaces due to acid attack caused by the nitrifying biofilm covering the tank surface. Therefore, chemical protection of aeration tanks is vital to preserve concrete and extend the service life of a wastewater treatment plant.

TCI offers exclusively high chemical resistant coating system, which has proved to be stable and resistive to chemical environment and acid solutions usually found in the wastewater treatment plant environment. TCI protective coating systems passed many Extreme Wastewater Analysis Tests (SWAT), which is an accelerated test of the harsh environment in wastewater treatment plants.
