The Umbrella Pipe System is an advanced pre-support method used in tunneling projects to reinforce weak ground conditions before excavation begins.
Steel pipes are installed ahead of the tunnel face and typically filled with grout injection to increase ground load capacity, reduce deformation, and prevent collapses.
This method significantly improves tunnel safety, provides better excavation control, and ensures project continuity in challenging geological conditions.
Manufactured from high-strength steel at Northic Group’s facilities in Ankara and Ereğli, umbrella pipes are available in various diameters and lengths to meet project-specific requirements.
Perfectly suited for the Gulf region’s infrastructure needs—including metro systems, road tunnels, and underground facilities in the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain and Oman—Northic umbrella pipes deliver reliable, safe, and cost-effective tunneling solutions.
