‍LINER

The Pro Line UV-CIPP liner is designed to deliver exceptional structural performance and longevity, with a certified Service Life of 100 years (in accordance with ISO 7684). This rigorous standard ensures the liner has been independently tested and validated to withstand long-term loads, aggressive environments, and real-world operating conditions. By significantly extending the functional life of underground assets, Pro Line helps municipalities and asset owners reduce total lifecycle costs and minimize the frequency of disruptive interventions.

For installation contractors, a certified 100-Year Service Life offers a major commercial advantage—supporting stronger project bids and instilling confidence in clients seeking dependable, long lasting rehabilitation solutions.

Pro Line’s UV-CIPP liner is engineered with a high glass content, multi-layered construction that delivers superior mechanical strength while maintaining a slim wall profile. Manufactured using precision-laid fibreglass mats and advanced resin systems—this design enables the liner to meet demanding static load requirements, even under high groundwater pressure or deep installations. The result is a robust yet efficient solution that allows for reduced wall thickness without compromising structural performance.

In accordance with ISO 7684 testing standards, the liner demonstrates excellent short-term circumferential modulus values, making it a dependable choice for both standard and high-load rehabilitation projects. Whether installed in shallow urban mains or deep trunk sewers, Pro Line provides the strength and reliability asset owners and engineers demand.

The Pro Line UV-CIPP liner features a permanent inner foil option that remains securely in place after curing, delivering both functional and operational advantages. This integral layer creates a smooth, abrasion-resistant surface that enhances hydraulic performance by improving flow efficiency and reducing the risk of debris buildup.

In deep or large-diameter pipelines, where access is often limited and confined space entry poses significant risks, the safety benefits of a permanent inner foil become even more pronounced. Because there is no need for personnel to enter the pipe to perform additional surface work after curing, overall risk exposure is minimised. This contributes to a safer working environment, helps meet stringent health and safety standards, and supports more efficient project delivery under challenging conditions.

The Pro Line liner is widely recognised throughout the trenchless rehabilitation industry for its exceptional ease of installation. Its lightweight design, flexible structure, and smooth handling characteristics make it easier for contractors to maneuver and position—especially in tight or challenging work environments. This user-friendly nature translates into faster installation times, reduced labor requirements, and increased on-site efficiency, ultimately lowering project costs and minimizing disruption to surrounding communities.
