Forepoling

Forepoling solutions enhance safety and stability in tunneling and geotechnical projects by securing excavation faces across various ground conditions, from rock to soft soils. Key products, such as the innovative AT – Pipe Umbrella System, feature advanced connections for faster, mechanized installation and improved load capacity.

Drainage and injection drilling systems

Our Drainage and injection drilling systems improve safety and ground stability in tunneling and geotechnical projects. Easy to install and adaptable, they provide efficient temporary and permanent dewatering. The AT–Tubespile™ enables fast water removal near excavations, while the AT–Drainage System ensures deep drainage along tunnels and water-saturated soils — reducing pressure and preventing delays.

Ventilation systems (Link to dsiventilation.com)

DSI Ventilation Systems is a global expert in underground ventilation for mining and tunneling. With over 50 years of experience, we deliver high-efficiency systems that improve air quality, enhance safety, and reduce operational costs.

Steel ribs and lattice girders

Steel ribs and lattice girders are essential structural elements used to support and stabilize tunnels during excavation. Steel ribs offer strong, adaptable ground control tailored to project requirements, enhancing load-bearing capacity and safety. Lattice girders provide a cost-effective, flexible framework for temporary or permanent tunnel lining, especially suited for shotcrete support in varying ground conditions.

LSC™ elements

LSC™ elements are engineered to absorb large ground deformations in weak or high-stress tunneling conditions. Installed in joints of the primary lining, they prevent structural damage by releasing stress in a controlled manner. Customizable and proven in demanding projects, LSC™ ensures safer, more resilient tunnel construction.

Soil nails and ground anchors

Soil nailing is a passive reinforcement method that stabilizes slopes, retaining walls, and underground excavations. Our self-drilling nails are grouted during or after installation, providing efficient and reliable support against ground movement in challenging conditions.

Overcoming loose ground with smart support

In South Tyrol, northern Italy, the Bronzolo Bypass Tunnel is the final step in a decades-long project to divert heavy traffic from the SS12 “Brennerstaatsstraße” (one of Italy’s most historically significant north–south corridors) in the section south of Bolzano, between San Giacomo and Bronzolo. Once completed, it will bring lasting relief to the community of Bronzolo.
