UV-GRP pipe lining
For larger gravity pipelines, we use UV-cured glass-reinforced liners installed and cured using specialist ProKASRO UV equipment. UV-GRP liners provide high structural performance with controlled factory impregnation, relatively thin wall sections and a smooth internal finish.
Our UV curing capability generally covers approximately DN150 to DN1500, subject to liner design, pipe geometry, access and installation conditions. The liner is inflated against the host pipe and cured by moving a controlled UV light train through the installation at the specified speed and lamp output.
Small-diameter UV and localised lining 2
For smaller drains and localised defects, we can install felt, glass-fibre and UV-LED cured repair liners. Our compact UV-LED systems are suitable for selected repairs in approximately DN100 to DN225 pipelines, including short liners, patch repairs and lateral junction rehabilitation.
Structural design
Where structural rehabilitation is required, the liner is designed for the specific asset. Design inputs may include pipe diameter and shape, host-pipe condition, depth, groundwater, soil and traffic loading, ovality, internal pressure where applicable, material properties and required design life.
Depending on the project, the liner may be designed as fully structural, semi-structural or non-structural. Specialist design is completed using recognised engineering methods, manufacturer design software and project-specific information.
