Global Tunnel Boring Machine Market

A tunnel boring machine (TBM) is a cutterhead machine used to excavate tunnels with a circular cross-section through a variety of soil and rock strata. Key advantages of TBMs include higher accuracy compared to drill-and-blast methods of tunneling, minimal surface settlement, and less noise and vibration. TBMs find widespread applications in transportation infrastructure development such as road, rail and metro tunnels. The growing need for efficient transportation networks is driving the demand for TBMs globally.

The Global Tunnel Boring Machine Market is estimated to be valued at US$ 6,705.8 MN in 2024 and is expected to exhibit a CAGR of 4.9% over the forecast period 2024 to 2031.

Key Takeaways

Key players operating in the Global Tunnel Boring Machine are Komatsu Ltd., SN Mercantile India Pvt. Ltd., High Speed Two Ltd., Amberg Engineering, Mammoet, Hitachi Zosen Sakai Works, China Railway Tunnel Group, Sika AG, Liaoning Censcience End-Use Co. Ltd., Kawasaki Heavy Industries, Ltd., Herrenknecht AG, The Robbins Company, TERRATEC Ltd., Japan Tunnel Systems Corp., Mitsubishi Heavy Industries, Ltd. Tunnel boring is gaining popularity in developing regions due to growing urbanization and infrastructure spending by governments, which is opening new opportunities for TBM manufacturers. Global expansion of key TBM manufacturers through regional offices and strategic partnerships will further aid in tapping emerging markets.

Market Drivers and Restraints

Increasing investment in transportation infrastructure projects across the globe driven by urbanization is a key factor driving the demand for Global Tunnel Boring Machine Market Size. Government initiatives to upgrade existing infrastructure and develop new metro and rail networks provide numerous opportunities for TBM manufacturers. Rising cost of labor is also encouraging the use of mechanized tunneling techniques such as TBM boring over conventional drill-and-blast methods.


High initial costs associated with TBMs acts as a major restraint for their adoption, particularly in cost-sensitive developing markets. Challenges associated with tunneling through complex geological strata such as high pressure ground can also increase project risks and costs. Logistical difficulties and expertise required for TBM transportation and erection in remote project locations further hinder the growth of the global TBM market.


Segment Analysis
The global tunnel boring machine market is dominated by the slurry TBM sub segment. Slurry TBMs use a slurry, or slurry seal, to stabilize the tunnel face by balancing underground pressures and keeping the face open after the cutting tools have removed material. Since they can operate in weaker ground conditions compared to other types, slurry TBMs are widely used for soft ground tunneling applications. Growing infrastructure investments in developing regions where tunneling often requires passing through soft soil or sand have boosted demand for slurry TBMs.

Global Analysis
The Asia Pacific region holds the largest share in the global tunnel boring machine market and is expected to continue to dominate during the forecast period. This is due to the increasing infrastructure investments by China, India and other Southeast Asian countries to develop metro and railway networks. Projects such as China's extensive high-speed rail network and India's metro rail expansions are driving demand. Europe is another major regional market for tunnel boring machines owing to ongoing investments to expand and upgrade transport infrastructure across the region.
