United Infrastructure–SoilDri AMP8 partnership: reuse and reinstatement lessons for engineers

30 Second Briefing
United Infrastructure and SoilDri have agreed a national innovation partnership for AMP8 utility works, centred on on-site treatment and reuse of excavated materials instead of landfill disposal and imported aggregates. The collaboration deploys SoilDri SEM, a utilities-focused soil improvement solution for reinstatement, and the TSM-5, a road-towable soil mixing unit that processes spoil directly at source. Reduced lorry movements, lower embodied carbon and less community disruption are key outcomes as the approach is rolled out across UK utility infrastructure projects.
Technical Brief
- SoilDri’s approach has already been validated through a United Infrastructure Supply Chain innovation award, de-risking wider rollout.
Our Take
United Infrastructure’s recent UK portfolio in our database spans gas terminals, listed gasholder redevelopment and large-scale housing upgrades, so a SoilDri tie-up for AMP8 likely positions them as a go-to contractor for utility clients seeking both civils delivery and sustainability-led ground treatment solutions.
The £11m cathodic protection upgrade at National Gas’s Bacton terminal and the Cadent Bromley-By-Bow Gasworks scheme show United Infrastructure already embedded in regulated energy networks, which should translate well into the compliance-heavy AMP8 water environment where asset protection and soil management are under similar scrutiny.
United Infrastructure’s planned acquisition of Wood’s UK transmission and distribution engineering business signals a strategy to control more of the technical value chain; integrating a specialist like SoilDri into AMP8 work would extend that approach into geotechnical and materials handling on water-sector projects.
