A Dundee business specialising in developing and manufacturing sustainable screw pile and ground screw foundation systems has surpassed £9 million in turnover.
Founded in 2019 by Callum Milne, RADIX‘s innovations support renewable energy, transport and infrastructure, modular construction, leisure and tourism, and residential development projects.
RADIX’s says its concrete-free screw pile foundation systems reduce embodied CO₂e by over 60% compared to traditional civils methods, while delivering ‘faster, cleaner’ installation with no excavation or spoil removal.
Since launching, the team has grown to 22 employees, based between the company’s Dundee headquarters and its Chelmsford operational hub.
RADIX operates its own commercial installation division, delivering an end-to-end service in the battery energy storage system space and on larger-scale projects. Complementing this, the company’s accredited and approved No More Digging network is strategically placed across the UK, supporting RADIX’s teams and delivering a wide range of installation services across multiple sectors.
The company’s continued growth is said to correlate directly with growing pressure to deliver infrastructure faster and reduce carbon emissions. With turnover forecast to reach £12 million in 2026, the business said it is ‘firmly on an upward trajectory’ – driven by sustained demand across renewable energy, infrastructure, and development sectors.
From its Dundee HQ, the company supports projects across Europe, Scandinavia, Australia, New Zealand and the Middle East. RADIX was recently involved with SUPERNODE, a major Australian battery energy storage project which incorporated RADIX’s structural platform and screw pile systems, demonstrating the scalability of its solutions in major global renewable energy markets.
In September 2025, the company launched a next-generation torque monitor in collaboration with Datum Electronics. The new system is described as setting a benchmark for torque monitoring in portable ground screw installation, delivering real-time, high-accuracy data directly to smartphones and tablets on site.
These investments support the company’s ambition to scale, with a target of £20 million turnover within the next three years, all while retaining engineering expertise and operational capability in Scotland.
Callum Milne, MD (products) at RADIX, said, “Dundee has always been a city defined by innovation, resilience and ambition, and we are really proud to be part of that story. We founded RADIX with the belief that engineering and sustainability could work hand in hand. Today, we are supporting projects around the world while continuing to invest, innovate and grow here in Scotland. It is important that our success reflects positively on Dundee and demonstrates the quality of engineering talent and expertise that exists here.”
