In the race to meet the UK’s ambitious net zero targets and secure energy resilience for generations to come, nuclear power plays a central role. But delivering this vital infrastructure is not just about reactor technology, funding, regulatory approvals, and skilled workforces. It also relies on something more fundamental: materials. At Tarmac, we know that getting the right materials, in the right place, at the right time is critical to successful infrastructure projects, and nowhere is this truer than in nuclear project delivery.
As the UK accelerates the rollout of new nuclear generation, from large-scale plants like Sizewell C to future Small Modular Reactors (SMRs), the scale and complexity of material supply cannot be overstated. Our experience shows that proven, tested, and traceable supply chains are not just a nice-to-have; they are nuclear-ready essentials.
From source to site: Consistent, nuclear-ready materials
Every nuclear project demands certainty. This certainty must be built in well before the first pour of concrete. Projects require the demonstration of consistent quality and technical performance – repeatable, fully traceable, and sustainable over a 10-year programme. That’s why our materials, sourced from our own quarries and transported via our extensive logistics network, meet the exacting technical standards required for licensed nuclear sites.
This means working in close partnership with our clients from the earliest planning stages to define the correct geological sources, assess mineral characteristics, and develop specialist mixes that satisfy nuclear safety cases.
We’ve supplied some of the most complex nuclear and defence-related sites in the UK. Through our parent company, CRH, we also bring deep international experience and best practice from major projects in Europe and the US. This track record positions us as a critical infrastructure partner—trusted to deliver the materials backbone of the UK’s nuclear future.
End-to-end logistics: Resilient, low-carbon, community-focused
A high-performance nuclear material is only as good as the system that delivers it. That’s why our integrated logistics solutions, by road, rail, and sea, are purpose-built for major infrastructure. Nuclear projects are often in remote or sensitive areas, and delivery windows can be tight. Our nationwide network and robust supply chain give clients the reliability they need to stay on programme.
Tarmac is a forward-thinking business. We invest in the development of material sources and logistical hubs near project regions and reduce the complexity of supply requirements. This not only streamlines delivery but also reduces transportation impact and creates new job opportunities in host communities.
Major projects, major expertise
Whether supporting the Sellafield PPP programme, contributing to HS2, or enabling low-carbon energy at Whitelee Wind Farm, our team has consistently delivered on the UK’s most complex infrastructure projects. This experience, combined with our industrial asset base and expert freight capabilities, makes Tarmac a cornerstone partner for nuclear’s next chapter.
