HILLHOUSE Group has unveiled a major expansion with a new asphalt production facility in Scotland.
The Edinburgh Asphalt plant at Soutra Mains Quarry is currently under construction and set to open in Autumn 2026, strengthening the firm’s position across Scotland.
The facility will bring locally produced, quality-assured asphalt supply to the east of Scotland for the first time under the Hillhouse name. The new facility marks a step forward for the group as it expands its operational footprint.
Mark Munro, Hillhouse Quarry Group MD, said, “Edinburgh Asphalt represents a significant moment for Hillhouse Group. We have long had the capability, the people and the operational foundation to serve the east of Scotland more fully, and this investment is the natural next step.
“For customers across Edinburgh and the surrounding area it means access to locally produced asphalt backed by the quality standards and service commitment that Hillhouse has built its reputation on.”
The addition of the asphalt offering completes the site as a full-service construction materials operation, capable of meeting the needs of local authorities, infrastructure contractors, surfacing and civil engineering firms, housebuilders and developers across Edinburgh, the Lothians and throughout the rest of Scotland.
The announcement builds on a period of significant development for the Group. In January 2026, Hillhouse appointed Alistair Borthwick as chief executive officer, bringing extensive strategic and financial experience from a career in complex, large-scale organisations.
Edinburgh Asphalt will be backed by a dedicated operational team with extensive experience in asphalt production, quality assurance and customer service when it launches in autumn 2026. The facility will produce more than 50 asphalt mixes, all manufactured to CPR certification and BS EN 13108 standards, additionally the final products will have the UKCA marking ensuring the product is produced, tested and controlled as set out by industry standard.
The plant is designed to serve customers across a broad area of eastern Scotland, with strong access via the A68 corridor supporting efficient collection and delivery logistics. A dedicated fleet will operate from the site from opening.
