Bastion is a self-delivery heavy civil contractor. Own plant, own crews, own concrete — and the certainty to finish what we start. Viaducts, sea walls, deep foundations and the substructures the headlines never mention.
No subbie chains, no finger-pointing. Plant, crews and concrete under one roof — so the programme is ours to control and ours to answer for.
Bulk excavation, cut-and-fill, remediation and site formation at scale.
Insitu and precast structures poured by our own concrete crews.
Viaducts, underpasses and marine structures from piling to deck.
SuDS, deep drainage and utility diversions across live sites.
Controlled demolition, asbestos clearance and enabling works.
Carriageways, junctions and rail civils delivered under possession.
Three decades of heavy civil delivery. Every job below is one we put in the ground — viaducts, defences and the substructures that hold everything else up.
Bastion is a self-delivery heavy civil contractor. Own plant, own crews, own concrete. We take the projects that need certainty — and we finish them.
From the first dig to the final pour, the same people carry the job. That's how a programme stays honest and a price stays one you can hold us to.
Climb into the cab and drive our plant around a live Bastion site. A 3D walkthrough of how we work — earthworks, structures and the machines that move them.
