Dam Spillway Repair & Structural Rehabilitation – Middle Marsyangdi Hydropower Project

Dam Spillway Repair & Structural Rehabilitation – Middle Marsyangdi Hydropower Project

The spillway at the Middle Marsyangdi Hydropower Project handles strong discharge forces and continuous sediment flow, creating progressive wear on concrete surfaces and structural elements. To maintain operational reliability, our team undertakes a comprehensive repair and rehabilitation program tailored to the site’s demanding hydraulic conditions.

The work includes rebuilding deteriorated concrete sections, reinforcing vulnerable zones, and applying protective systems that strengthen the spillway’s performance under high-flow operation.

Scope of Work

Concrete Restoration:

  • Reconstruction of damaged spillway areas using high-strength repair concrete to re-establish durability and structural capacity.

Crack Control & Sealing:

  • Precision crack injection and joint treatment to stop leakage, stabilize affected zones, and prevent further deterioration.

High-Performance Protective Mortar:

  • Application of abrasion-resistant mortar overlays engineered to withstand fast-moving water and sediment impact.

Reinforcement & Stability Enhancement:

  • Targeted strengthening of identified weak spots to ensure the spillway remains stable during peak discharge conditions.

Project Highlights

  • Delivered a tailored rehabilitation program suited for high-energy spillway environments.

  • Improved resistance against hydraulic wear with durable repair and protection systems.

  • Enhanced overall structural performance, supporting reliable hydropower operations.
