Underground construction for any purpose like road tunnels, railway tunnels, metro and utility tunnels are subjected to severe stress from nature. They require construction systems able to ensure durability and a constant protection against ground water and environmental exposure while must simultaneously be able to withstand the requirements of different operating modes. Sigunit, Sikament, Sika Viscocrete, Sika Plan membranes are our hystorical brands that found along decades and still find nowadays extensive applications in tunneling works.

These products are the fruits of 100 years of experience, continuous improvement, innovation and state-of-the-art production sites. The product range comprises all major technologies to offer you the best solutions for your projects.

Key points for efficient underground excavation:

  • Adequate setting time for shotcrete with low rebound
  • Immediate support
  • Sealing and waterproofing technologies
  • Durable concrete lining

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. TBMs reduce disturbance in the excavation area which makes them ideal for use in heavily urbanized areas. They will also produce a smooth tunnel wall that reduces the cost of the final lining.
The total excavation time of long tunnels is also significantly reduced with TBMs in comparison to conventional excavation methods. Sika provides a wide range of products that are designed specifically for use with all of these different variants of TBM, and throughout the whole of their tunnel excavation and construction process.
