STRABAG is synonymous with the tunnel construction industry, consistently developing and investing in new approaches, ensuring the highest level of quality during planning, construction, and completion.

We offer a range of comprehensive tunnelling solutions with in-house capability for all tunnelling techniques.

Tunnelling capabilities in the UK

STRABAG UK combines cutting-edge technology with extensive technical know-how to seamlessly transform ambitious tunnelling projects into reality.

Our world-leading tunnelling specialists deliver sophisticated, efficient tunnelling solutions to projects in both complex urban environments and rural areas, ensuring minimum impact on the surrounding environment and communities.

Drill and blast

The precision drill and blast tunnelling technique allows our expert teams to tackle the toughest geological conditions.

The approach can be tailored to the hardness and composition of the rock, allowing us to adapt to varying geologies.

This advanced method ensures maximum accuracy and efficiency, opening the door for ambitious projects in challenging environments.

Tunnel boring machines

Beneath the surface, STRABAG UK’s state-of-the-art tunnel boring machines (TBMs) work like underground factories - cutting through earth, removing material, and lining tunnels with concrete segments.

Able to adapt to each project’s unique demands, STRABAG UK is highly experienced at building subterranean networks while life above ground continues uninterrupted.

Shafts

At STRABAG UK, we recognise that tunnel shafts are essential for safe and efficient underground construction. Connecting tunnels with the surface is vital at each stage of tunnel construction.

We are able to construct a wide range of shaft solutions depending on the depth and geology of the site.

Sprayed concrete lining

The use of the sprayed concrete lining (SCL) technique allows for safe tunnelling construction in complex ground conditions and is also time efficient. Advanced machinery sprays concrete directly onto tunnel walls to provide support and stability during the excavation process.

This technique is adaptable and ideal for projects that require flexibility in changing ground conditions.

Waterproofing

The STRABAG Waterproofing Department brings expertise and innovation to every project, ensuring durable, high-quality waterproofing for tunnel and civil engineering projects, restoration and grouting systems, roofs, and the use of membrane application machines.
