Civil Construction
Saltire delivers end-to-end civil construction services with a flexible, client-first approach—ensuring quality outcomes across roads, drainage, earthworks, and concrete works.

Industry Leading Technology
We harness a unique mix of technologies and solutions to ensure your system continuity during repairs. This includes hot tapping, flow stopping and s-gate valves.

Live Water Mains Inspection
Advanced live inspection technology detects issues in pressurised pipelines—maintaining network integrity without isolations, shutdowns, or service disruption.

Hot Tapping
Saltire Infrastructure utilises high-pressure rated Hot Tapping Equipment for the fast and safe installation of new branch connections and bypass mains, with the current capability to install DN25-DN400 offtakes.

Flow Stopping
Line Stopping allows works to be undertaken on water mains without interruption to customer supply. Deploying a stopper and bypass system, the rig set-up allows for sections of pipelines to be made dry allowing safe repair or replacement of the existing network.

S-Gate Valve
Saltire Infrastructure’s S-gate Valve System is a WSAA-approved live insertion valve system, designed to be used on live under pressure pipelines, providing mechanical isolation on the network to operator’s requirements and a future asset on the pipeline network to be used time and time again.
