SALOC specializes in UV Glass Reinforced Plastic lining (UV GRP). This is the dominant relining technology in Europe and is quickly becoming a market leader in North America.
Discover the applications of UV lining technology as we revolutionize the way culverts are restored and fortified. Culverts, vital for managing the flow of water under roads, railways, and trails, play a vital role in maintaining safe and functional transportation networks. Whether you're dealing with aging culverts, erosion-related concerns, or simply in need of preventive maintenance.
Manholes structures that are designed to allow maintenance personnel to enter, inspect, clean, and perform repairs on the underground infrastructure. UV lining technology utilizes ultraviolet light to cure a specially designed lining material within existing manhole infrastructure. Resulting in fully rehabilitated manholes with improved structural integrity and an extended lifespan.
Sewer & Water:
Sewers are an essential part of urban infrastructure designed to transport wastewater to treatment plants. This trenchless solution eliminates the need for extensive digging and reducing project timelines. UV lining technology effectively addresses various sewer issues, including cracks, leaks and corrosion, providing tailored solutions to meet specific requirements.
UV CIPP, or Cured In Place Piping, excels in environmental sustainability, efficiency, durability, safety and economic viability to rejuvenate underground utilities. The GRP (Glass Reinforced Polyester) liner arrives on-site factory-manufactured and quality control checked. It is installed in the host pipe and cured using specialized UV light equipment.
ADVANTAGES OF UV CIPP
The meticulous process before construction involves a comprehensive evaluation of ecological and safety aspects. By understanding the ecological context, appropriate measures can be devised to minimize disruption and mitigate any potential harm to the environment.
If any obstructions or damages are identified during the inspection process, appropriate measures are taken to address them before the construction begins. This may involve removing blockages using specialized tools or repairing any damages using appropriate techniques.
Planning and implementation of flow bypass measures are undertaken to redirect the sewage flow during the lining process. Flow bypassing ensures uninterrupted functionality of the sewer system and prevents any service disruptions to local residents or businesses.
Roles and responsibilities are defined, and briefings are provided to ensure all team members are well-equipped and informed. Liner is checked for defects or damage and the equipment for construction is prepared. Specialized machinery, such as winches and robotic systems, is inspected, calibrated, and tested to ensure it operates smoothly and accurately.
This involves carefully aligning the liner and securing it to the insertion equipment, such as a winch, which will facilitate the pulling process. The pulling process requires a skilled and experienced team to ensure precise execution and avoid any potential disruptions or damage to the liner or host pipeline. Effective coordination, and adherence to safety protocols are paramount throughout the operation.
Once the liner is deemed ready, pressurization commences. Air or other pressurizing agents are introduced into the liner, exerting controlled pressure that forces the liner against the interior surface of the host pipeline. This pressure facilitates the liner's adhesion to the pipeline walls and helps to eliminate any potential wrinkles or voids, ensuring a tight and secure seal.
Once the liner is in place and properly pressurized, various methods may be employed to facilitate its setting. One common approach is UV curing, which involves the use of ultraviolet lights to initiate a chemical reaction in the liner material, causing it to harden and solidify. UV light is applied evenly across the liner's surface, promoting rapid curing and ensuring uniform strength throughout.
The excess liner material, if any, is carefully trimmed away using specialized cutting tools or equipment. This trimming process ensures a smooth transition between the lined section and the remaining pipeline. In cases where the sewer system requires additional fittings or connections, such as bends, branches, or access points, the installation of fittings becomes crucial.
The final video inspection is a crucial step in trenchless sewer lining construction, serving as a comprehensive assessment of the completed work. Through the use of advanced video inspection technology, the lining quality, structural integrity, and the absence of obstructions or defects are verified. Recordings can be sent to customers for proof of finished work.
Efficient commissioning not only accelerates the overall project timeline but also minimizes disruptions to local communities and reduces the environmental impact associated with construction. It allows for a smooth transition from construction to operation. At SALOC we can confirm lining a minimum of one pipe per day, depending on the project.
