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

In March, Protech completed single line track renewals for our valued client BAM UK & Ireland at Ponts Mill Viaduct in Cornwall as part of their wider scope to renew the viaduct deck and provide further strengthening. 

We would like to thank our trusted partners – Explore Plant, Plantforce, Volker, Torrent Trackside, and GPX Engineering – as we successfully delivered our full scope of 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, our strength lies in our deep expertise and seamless project delivery. With dedicated in-house teams across rail and civils, engineering, monitoring, logistics, and support services, we offer a fully integrated approach to managing complex infrastructure projects from start to finish. This comprehensive capability – combined with our unwavering commitment to quality – is why clients trust us time and again.

Our scope of works included:

• Renewal of 145 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 metre 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. 

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