At the World Tunnelling Congress 2025 in Stockholm, Sweden, Normet announced the launch of a new sprayer for large tunnel profiles, the Spraymec 9100, along with a new spray boom update for the established spraying manipulator Minimec, allowing for an extended spraying reach.
Spraymec 9100 – A powerful sprayer for large-scale tunnel projects
The Spraymec 9100 is a purpose-built tunnelling sprayer designed for high-output sprayed concrete applications in large-profile tunnels and caverns. It combines the most advanced features from our entire sprayer lineup—including a best-in-class low-pulsation concrete pump, onboard compressor, and a 1,500-liter accelerator tank—into one powerful machine.
Offering exceptional productivity, the Spraymec 9100 delivers an extended spraying range with a maximum vertical reach of 19.5 meters and a spraying width of up to 28 meters. To ease the spraying process, our innovative SmartSpray boom control system comes as standard, and with the optional Remote Driving System, the machine can be relocated conveniently from ground level.
Minimec – proven spraying manipulator with an extended reach
The Minimec, a proven spraying manipulator designed for maximum efficiency and ease of use in confined underground spaces, is now available with an extended boom with a reach of 8.5 m, in addition to the standard boom with 7.5 m reach. It delivers enhanced manoeuvrability and precise spraying performance. Its compact design and advanced control system ensure smooth and accurate spraying, even in the most demanding conditions. Built for reliability and durability, the Minimec is the ideal solution for boosting productivity and safety in underground construction projects.
Continuous development to meet the unique customer demands of tunnelling
“The World Tunnelling Congress is a perfect platform to launch these expansions to both ends of our sprayer offering. The Minimec update sets a benchmark for efficiency and precision in confined spaces, while the Spraymec 9100 delivers powerful, high-quality spraying in demanding large-scale tunnelling projects.” states Toni Huttunen, Product Line Director of Tunnelling Sprayers at Normet.
With the launch of the Spraymec 9100 and longer-reach Minimec, Normet continues to expand its tunnelling equipment offering, demonstrating a strong commitment to serving customers and designing solutions that meet the evolving needs of a broader spectrum of tunnelling projects. These advancements underscore Normet’s continuous development to address the unique challenges and demands of tunnelling customers globally.
