Micro-Tunneling Works

In 1997, QBC was the nation's first to execute micro-tunneling technology. Since then, we have installed over 60 kilometers of pipeline by micro-tunneling in Qatar. In 2011, QBC received Construction Week's "Infrastructure Project of the Year" for the technically-challenging micro-tunneling drive done 27m below an open-water canal.

QBC is Qatar’s leading expert in micro-tunneling and boasts a large fleet of the world's best machines from USA, Italy and Germany. This technology allow for indefinite shaft depth with remotely operated, nondestructive underground tunnels up to four meters (4m) in diameter. These tunnels are used for many purposes, including pipelines, utility conduits and underground structures (e.g. pedestrian tunnels).
