Powerful tunnel boring machines (TBM) excavate through dirt and solid rock, carry away the materials, and install concrete—ready for construction of road or railway, mining shafts, or exploratory tunnels. Consisting of a large, powerful circular rotating cutting face, it has enclosed machinery that also stabilizes the newly dug tunnel.
Our high-tech machines enable high advance rates in any geology with maximum safety for buildings, infrastructures and personnel. Working in teamwork together, modern, integrated tunnel systems for metro, road, railway, passenger, supply and disposal tunnels are the result – built on budget and on schedule.
Tunnel boring machines (TBMs) are very advanced equipment used as an alternative to drilling and blasting through rock and "conventional mechanical excavation" in soft ground. Sika provides a wide range of products designed specifically for use with a variety of TBMs, throughout the whole tunnel excavation and construction process.
If you are in the trenchless industry, you are sure to be familiar with the legacy that Akkerman TBMs have created. While this time-tested and proven technology has been successfully installing thousands of tunnels around the world, we have been busy advancing the technology to maximize performance, expand capabilities, and increase …
