Precision tunnel boring, underground transit systems, and subsurface utility networks across Europe since 2011.
Earth pressure balance and slurry shield machines for metro, rail, and road tunnels up to 15m diameter. Real-time monitoring, minimal surface disruption.
Combined utility tunnels for power, water, telecoms, and gas. Modular cross-sections, seismic-rated lining systems, 100-year design life.
Secant pile, diaphragm wall, and caisson shafts for launch/retrieval, ventilation, and emergency access. Depths to 80m in variable geology.
Jet grouting, compensation grouting, dewatering, and ground freezing. We stabilize before we dig — protecting structures above and below.
3.2km twin-bore tunnel under the financial district. Navigating 19th-century foundations and active U-Bahn infrastructure at 28m depth.
12km combined utility corridor connecting port infrastructure to the city grid. Microtunneling through saturated alluvial soils below sea level.
Emergency and maintenance access tunnel parallel to the main Gotthard Base Tunnel. High-altitude Alpine conditions, mixed-face rock boring.
Cross-harbour tunnel segment connecting Zona Franca to the airport logistics hub. Working below the water table in reclaimed coastal fill.
