Druc Lining Stress Controller Honeycomb
India has been trying to spread its railway network to reach the remote and difficult border areas. A considerable portion of the railway tracks are to be placed inside tunnels and steep cut slopes in the treacherous mountainous regions, viz. J&K, India. Tunneling in Himalayas is often challenging due to various geological aspects. As the tunnel passes through young Himalayas thrust and shear zones, so it is a challenging job to excavate a tunnel. Shear zones, heavy water ingress and collapses have added woes to both management and contractors by risking man & machinery and subsequent economic damages. Effective tunneling solutions and their timely implementation is one of the ways to make the excavation stable and economic.

Hence, Geo Constech Pvt. Ltd., is constantly trying safeguard the interests of the Indian tunneling society by providing state-of-the-art ground improvement and stabilization solutions.

Geo Constech Safe Excavation
We are associated with Drucar ground support, Tensar International (UK), Bochumer Eisenhütte Heintzmann GmbH & Co. KG (Germany), Sireg (Italy), to bring cutting edge technology in India, as an aid for more cost effective and sustainable tunnelling operations. We have also partnered with leading engineers & scientists from various institute for design, testing, analysis and application.

Druc Stone
Our range of tunnel stabilization and support products include, yieldable TH profiles and stress controllers which are especially suited for the Himalayan regions, where squeezing tunnel conditions are prevalent. We also provide a wide range of chemical resins (2Com. & 1Com.) for water ingress control, crack repair, ground consolidation and cavity filling. Our water expandable rock bolts (GrippHolds) are finding widespread use in the Himalayan tunnels. We also supply all kind of rock bolts.

We are also extensively involved in the Polyurethane grouting in USBRL tunnels, in Reasi (J&K, India). Our design and product has been successful in arresting a heavy inrush of water, while at the same time consolidating the weak ground.

Finally, it is the endeavor of Geo Constech Pvt. Ltd. to bring the best of stabilization technology in India. Our Products and technologies are certified for strength, durability and safety. With their implementation and application, we can certainly make tunneling in India a safer and viable task.
