The Pakal Dul Hydroelectric Project is a large, 1000 MW run-of-river scheme under construction on the Marusudar River (a Chenab tributary) in the Kishtwar district of Jammu & Kashmir, India, featuring a 167m high concrete-face rock-fill dam, aimed at generating significant clean energy for India, developed by Chenab Valley Power Projects (CVPPPL). Key aspects include extensive tunneling, underground powerhouse, and its role in India’s strategic energy plans.

Challenges
The Pakal Dul Hydroelectric Project in Kishtwad faced challenges of high groundwater pressure, potential seepage through tunnel and dam joints, and the need for long-term structural stability in a difficult Himalayan terrain. Ensuring leak-proof operation while maintaining the integrity of critical hydroelectric infrastructure under variable pressures was essential.
Our Solutions
Re-injectable Grouting Tubes combined with PVC and Copper Water Stop Seals (WSS) provided a robust, adaptable solution for sealing joints and controlling seepage. The system allowed for post-construction grouting to maintain leak-proof conditions over time, even under high hydrostatic pressure. This solution enabled Jaiprakash Power Ventures Limited to ensure the Pakal Dul Hydroelectric Project’s operational safety, durability, and long-term reliability in a challenging environment.
