About Us
WHO WE ARE
Allied Infrastructure is a specialist contractor operating across the aviation and infrastructure sectors. Based in Leigh, we deliver complex, time-sensitive works nationwide, with a strong focus on safety, quality, and operational continuity.
Founded in 1994 as Allied Drilling, we have grown from a specialist subcontractor into a leading principal contractor, delivering projects at major airfields and defence sites across the UK and internationally.
Our strengths include self-delivery through a skilled direct workforce and specialist plant, extensive experience working in live operational environments, in-depth materials expertise, and a strong commitment to sustainability through initiatives such as our Carbon Reduction Plan and low-carbon product trials.
This combination of experience and capability gives our clients confidence that projects will be delivered safely, efficiently, and with minimal operational disruption.
In late 2025, Allied Infrastructure Management was acquired by DJ Civils. Allied continues to operate as the same business, now supported by the strength, shared expertise, and long-term investment of a specialist civil engineering group
