United Infrastructure, a leading provider of solutions for the UK’s critical infrastructure, and SoilDri, a specialist provider of sustainable soil improvement, have announced the launch of a national innovation partnership focused on transforming how infrastructure renewal is delivered – enabling utility clients to deliver at greater pace, lower cost and with improved outcomes for customers and communities as the industry progresses through AMP8.
The partnership follows SoilDri’s recent recognition at the United Infrastructure Supply Chain Awards, where the business received an Innovation Award for its approach to minimise soil-to-landfill, and emphasise value in soil reuse and sustainable utility delivery. The award recognised the environmental and operational benefits being delivered through the use of SoilDri SEM and the innovative TSM-5 soil mixing machine.
The partnership brings together United Infrastructure’s expertise in utility infrastructure delivery with SoilDri’s innovative soil reuse technologies, enabling excavated materials to be treated and reused directly on site rather than being removed to landfill and replaced with imported aggregates.
The announcement comes at a time when the utilities industry and its delivery partners are under increasing pressure to reduce waste, lower carbon emissions and maximise the reuse of excavated materials. Industry initiatives championed by organisations such as Street Works UK, together with evolving reinstatement standards, sustainability targets and a growing focus on circular economy principles, are driving change across the sector.
At the heart of the partnership is SoilDri SEM, a specialist solution developed specifically for the utilities sector that enables excavated materials to be improved and reused within reinstatement works. Supporting this approach is the innovative TSM-5, a road-towable soil mixing machine that allows treatment to take place directly at source.
Together, the technologies reduce waste, minimise lorry movements and community disruption, lower carbon emissions and improve project efficiency whilst supporting the delivery challenges facing the utilities sector throughout AMP8 and beyond.
The partnership forms part of a national rollout programme that is bringing sustainable soil reuse technologies to utility infrastructure projects across the UK.
Already being deployed on live utility projects, the partnership reflects a shared commitment to innovation, sustainability and delivering better outcomes for clients, communities and the wider environment.
At a time of unprecedented infrastructure investment, this partnership highlights how innovation can unlock faster delivery, lower carbon and reduced cost – ensuring AMP8 and AMP9 are delivered efficiently and at best value for customers and the wider UK economy.
Kelly Macfarlane, Managing Director of United Infrastructure Water, said:
The scale of infrastructure renewal required in AMP8 demands a step change in how we deliver projects. Traditional approaches alone will not meet the pace, cost, and sustainability challenges ahead.
At UI, we have a strong focus on innovation, supported by a dedicated team that identifies and develops new approaches to address the sector’s most pressing challenges. Our partnership with SoilDri is a direct result of this focus. It enables faster, more efficient delivery of essential water infrastructure, improving outcomes for customers and the communities that rely on these services.
By reducing waste, minimising haulage, and accelerating reinstatement, we lower carbon emissions and deliver works in a more sustainable way. At the same time, we support our water company clients in achieving better value for money while meeting their environmental commitments.
Dan Macey, Director of Strategic Growth at SoilDri, said:
“United Infrastructure has established a reputation for embracing innovation and challenging traditional approaches to project delivery. That makes them an ideal partner as we continue the national rollout of SoilDri technologies across the utilities sector.”
“The combination of SoilDri SEM and the TSM-5 enables excavated materials to be treated and reused directly on site, reducing reliance on landfill and imported aggregates whilst supporting faster, more sustainable project delivery. As the partnership expands, we will continue introducing additional SoilDri technologies across the utilities sector, helping contractors and asset owners reduce waste (in line with the top tiers of the waste hierarchy), lower carbon emissions and improve operational efficiency.”
The partnership will be supported by a programme of joint communications, project case studies and industry engagement activities throughout 2026, showcasing how innovation can support the UK’s infrastructure renewal ambitions and the delivery challenges associated with AMP8 and beyond.
