Tunnelling and Underground Works
Specialist underground excavation, rock support, shaft sinking, and microtunnelling for roads and utility networks.
// ENGINEERING OVERVIEW
How This Method Works On Site
Underground works require careful ground checks, strong rock support, and precise excavation to dig safely through changing geology. We construct tunnels, deep access shafts, and trenchless pipeline crossings across Oman.
Primary Execution Methods
Faulted rock zones, mixed soil and rock strata, utility corridors, and deep underground chambers.
3D tunnel shape monitoring, ground settlement sensors, and rock core strength checks.
