This project involved the structural rehabilitation of the dam and weir surfaces at the Middle Bhotekoshi Hydroelectric Station—a high-capacity, run-of-river hydropower project critical to Nepal's energy grid. The work aimed to restore surface integrity, improve durability, and ensure long-term resilience of water-retaining structures exposed to high-velocity flow and sediment abrasion.
Highlight: M80 & M60 Grade High-Performance Concrete Systems
A key technical success of this project was the placement of M60-grade high-strength concrete and the application of M80-grade thixotropic mortar for extreme wear resistance. These materials were chosen for their exceptional strength, durability, and bonding performance, vital for long-term reliability in harsh hydraulic conditions.
