IN Brief:
- Costain, A E Yates, and Hyperion Robotics will deliver 90 printed concrete sleepers.
- The components will support 1.3km of CO2 pipeline on Teesside.
- The approach is intended to reduce concrete and steel use by 40% and carbon by up to 50%.
Costain is introducing 3D-printed low-carbon concrete components into a live carbon capture scheme on Teesside, bringing additive manufacturing into a project with established delivery and performance requirements. Working with A E Yates and Finnish specialist Hyperion Robotics, the contractor will use around 90 high-strength printed concrete sleepers to support 1.3km of onshore CO2 pipeline forming part of the East Coast Cluster network.
The units are being manufactured using Hyperion’s robotic process, which removes the need for conventional formwork and is intended to give tighter control over geometry and material use. According to the project partners, the sleeper design reduces concrete and steel consumption by around 40% compared with traditional precast alternatives and cuts carbon emissions by up to 50%. The components are also described as lighter than conventional units while maintaining the required structural performance for the installation.
The choice of application is telling. Pipe support bases are repeatable, engineered components with clear loading requirements and relatively straightforward geometry. That makes them a practical place to test manufacturing methods that promise material efficiency without introducing unnecessary design risk. Much of the discussion around 3D-printed concrete has focused on demonstration projects and experimental structures. Teesside is a more grounded use case, built around an infrastructure component that has to perform within the constraints of a live project rather than a showcase exercise.
The link to carbon capture infrastructure adds another layer. Major decarbonisation projects are increasingly being assessed not only on their long-term operational effect, but also on how they are built. Infrastructure intended to reduce industrial emissions comes under closer scrutiny if high-carbon construction methods are used where viable alternatives exist. That has pushed contractors and clients to look more closely at embodied carbon, offsite manufacture, material reduction, and the repeatability of lower-carbon components.
There are also practical project benefits if the claimed efficiencies hold up on site. Lighter components can reduce handling demands, while lower material volumes and the elimination of formwork can simplify manufacture and shorten some production steps. The commercial test will be whether those gains are preserved once transport, procurement, approval, and supply chain integration are taken into account. Adoption of new concrete manufacturing methods rarely depends on a single technical advantage. It depends on whether the overall package can be delivered reliably, repeatedly, and at a cost the market will accept.
That is why projects like this tend to matter more than highly visible prototypes. They show where the industry is most likely to adopt additive methods first: not in one-off architectural statements, but in repeat infrastructure components where precision, standardisation, and material efficiency all count. If the Teesside units perform as intended, they will strengthen the case for applying the same approach to other civil and utility components that sit closer to routine procurement.
Construction has been slow to move away from conventional concrete manufacture, in part because established methods are well understood and deeply embedded in design, assurance, and supply chains. Changes come more readily when they can enter the market through familiar component types rather than wholly new systems. That is the opening Costain and its partners are testing on Teesside — a route into additive concrete led by infrastructure pragmatism rather than novelty.
