Tunnelling

Shotcrete plays a vital role in tunnel construction, as it immediately supports the surrounding rock mass after excavation. However, conventional shotcrete has limited flexural strength, making it less flexible under load.
By adding Bajaj Fibre Tuff (macro synthetic polypropylene fibre), the flexural strength of shotcrete is significantly enhanced, allowing it to carry higher loads and prevent brittle failures.
Globally, research is moving towards replacing steel reinforcements in tunnel linings, and we provide a complete solution with Bajaj Fibre Tuff at the designed dosage, offering safety, durability, and cost efficiency. This fibre is lightweight, easy to handle, and offers a cost-saving of 50–60% compared to steel reinforcement.
