What DSI Underground does

DSI Underground is a Berlin-headquartered supplier of ground control solutions for the underground mining and tunneling industry, founded in 1865 and operating with 1,001–5,000 employees. Its product portfolio spans ground support hardware (bolts and cables, mesh, chemicals and grouts including fast-curing resins and high-strength grouts), geotechnical measurement instruments for soil, rock and structural condition monitoring, and digital systems for real-time ground support performance monitoring and control. The offering is integrated with a Ground Support App that provides mobile access to product data sheets, pull tests, and resin/mesh requirement calculations, and is complemented by ground support services covering technical support and on-site consultation.

DSI Underground was acquired by Sandvik in 2021 and now operates as part of Sandvik's Mining and Rock Solutions ground support division. The acquisition combined DSI Underground's ground control portfolio with Sandvik's broader mining and tunneling equipment business, creating a comprehensive offering that is sold through direct sales, service contracts, and Sandvik's global distribution network. Prior to the Sandvik acquisition, DSI Underground also acquired Edvirt AB in March 2021 to bolster digital ground support capabilities.

The company serves two primary use-case segments — Underground Mining and Tunneling — addressing pain points including rock stability hazards, worker safety risks, ground collapse prevention, water ingress, and ground movement monitoring. Customers are mining operators and tunneling contractors; the business model is industrial B2B sales of consumables, hardware, geotechnical instruments, and digital monitoring systems, supplemented by technical services. Revenue figures and pricing details are not publicly disclosed.

Direct peers

• Normet: Normet provides equipment, consumables, and services for underground mining and tunneling, including rock reinforcement bolts, resins, and sprayed concrete (shotcrete) systems. It competes directly with DSI Underground in ground support consumables and grouting solutions for the same mining and tunneling customers.
• Minova: Minova, owned by Orica, supplies ground support products including rock bolts, resin capsules, anchors, and injection chemicals for mining and tunneling. It is one of the closest direct competitors to DSI Underground in rock reinforcement consumables.
• Jennmar: Jennmar is a major global manufacturer of ground control products for mining, including roof bolts, resin cartridges, mesh, and cable bolts. It serves the same underground mining customers as DSI Underground with a comparable consumables-focused portfolio.

Broad incumbents

• Epiroc: Epiroc is a major underground mining and infrastructure equipment OEM with a growing ground support and rock reinforcement offering. It overlaps with DSI Underground's customer base across underground mining and tunneling, though its ground support portfolio is narrower than DSI's.
