Structural and semi-structural close-fit PE lining systems

Opt for our Rolldown and Subline PE pipe lining systems, the epitome of strength and resilience, for unmatched corrosion resistance and capacity retention. Perfectly suited for water, wastewater, utility gas networks, and oil and gas systems. Tailored precisely to your project's needs, our PE liners boast specific SDRs, backed by our team of experts who ensure excellence at every stage.


Our RollDown system is the pinnacle of pipeline renovation, boasting thick walls and full pressure ratings to strengthen weakened mains. Using standard PE pipe, it undergoes a diameter reduction of approximately 10% through roller sets, seamlessly integrating into host pipelines via conventional sliplining techniques. With polyethylene pipe sizes from 100mm to 500mm, RollDown ensures maximum flow capacity, making it a cost-effective and environmentally friendly alternative to open-cut replacements.
