Structural Works – Viaduct Deck Replacement & Strengthening at Ponts Mill, Cornwall

In March, Protech Infrastructure undertook a complex and rewarding structural project at Ponts Mill Viaduct in Cornwall. Working closely with our trusted partners – Explore Plant, Plantforce, Volker, Torrent Trackside, and GPX Engineering – we successfully delivered essential deck replacement and structural strengthening works on this historic section of the railway.

This was a challenging project, one that demanded specialist knowledge, seamless coordination, and precision delivery. It’s exactly the kind of work where collaboration across disciplines makes all the difference – and where Protech’s reputation for excellence comes to the fore.

At Protech Infrastructure, we pride ourselves on the depth of our expertise and speed of delivery. With multiple in-house departments dedicated to engineering, monitoring, logistics, and support services, we’re able to manage and execute complex infrastructure projects end-to-end. It’s this full-service capability – along with our commitment to quality – that keeps clients like BAM UK & Ireland coming back.

Our scope of works included:

• Renewal of 45 meters of single line track using composite sleepers, including two gathering panels and reinstatement of guard rails with MOW clip fastenings
• Tamping to achieve precise design geometry
• Installation of a new TTS troughing route through the viaduct
• Back-of-wall drainage installation at both abutments

But that’s only part of the story. Our structural and track monitoring teams were on hand throughout the works, deploying state-of-the-art technology to ensure safety, compliance, and performance. Meanwhile, our haulage division kept the project moving smoothly by delivering all required materials – including 18.288 meter rails – directly to site.

At the heart of a successful job like this is partnership: working with experts, sharing knowledge, and staying focused on the common goal – delivering for the client. We’re proud to have played a key role in this project and grateful to our partners for their professionalism and support.

We look forward to working together again soon on the next successful collaboration.
