Versarien administration: implications for graphene concrete and materials R&D
Reviewed by Tom Sullivan

30 Second Briefing
Administrators have been appointed to AIM-listed Versarien, developer of the Cementene graphene admixture and partner in HS2 trials of graphene‑reinforced 3D‑printed concrete with the Skanska Costain Strabag JV. The company, which helped Banagher Precast Concrete cut ordinary Portland cement content by 20% in a standard precast mix and signed a materials R&D agreement with Balfour Beatty, entered administration on 6 January 2026. Persistent losses of £4.3m on £2.4m revenue in the latest year and failed investment and M&A efforts triggered the move, with Leonard Curtis now seeking buyers for the business and assets.
Technical Brief
- Cementene admixture enabled Banagher Precast Concrete to remove 20% OPC from a standard precast mix.
- HS2 trials with Skanska Costain Strabag JV used graphene reinforcement in 3D‑printed concrete elements.
- Balfour Beatty’s agreement with Versarien focused on co-developing new graphene-enhanced concrete mix designs.
- Financial performance deteriorated from £5.4m revenue and £14.3m pre‑tax loss to £2.4m revenue and £4.3m loss.
- Leonard Curtis was first engaged in May 2025 in an advisory role on turnaround options.
- An accelerated M&A process initiated August 2025 failed to secure an acceptable going‑concern proposal before cash ran out.
Our Take
Versarien’s move from a December 2025 notice of intention to appoint Leonard Curtis (already flagged in our earlier coverage) to full administration on 6 January 2026 effectively ends near‑term scaling prospects for its Cementene admixture on HS2 and National Highways trials, forcing contractors like Balfour Beatty and Banagher Precast Concrete to consider alternative low‑cement mixes or renegotiate IP access.
The latest accounts in the article facts show revenue more than halving year‑on‑year while losses remained high, a pattern our Materials coverage often associates with niche construction tech suppliers whose products are tied to a small number of flagship projects such as HS2 rather than broad market adoption.
With the United Kingdom as the sole country listed and the ‘Digital Roads of the Future’ project named, Versarien’s administration removes one of the few UK‑based graphene concrete players appearing in our 20 Materials stories, likely opening space for rival admixture technologies in future National Highways and HS2 procurement rounds.
