Our Work

The detailed study for construction of the tunnel include understanding with respect to the choice of the liner & method of excavation, the challenges posed by the stratigraphy, the joint patterns, seapage zones, etc. For this Geological Mapping and Pressuremeter & Flat Jack tests form the important tools. Various markets have been served by Noble Geo-Structs:

• Water supply tunnels – The depth for these tunnels have been about 100 m below the ground level.

• Metro – The safe excavation procedures along with the design for tunnel liners using extensive Finite Element Method (FEM) have been recommended.

• Railways - The geology of the proposed area for tunnel was analysed by conducting extensive geological mapping and running large number of Pressuremeter tests at the crucial locations.

So far the tunnel projects are completed at:

• Malbar Hill – S.K. Patil Udyan – Kilachand Garden

• Modaksagar Tunnel

• Bhandup-Malad-Charkop Tunnel
