Hyderabad Metro Rail Challenges and Project Scope:

In response to the escalating traffic volumes in the rapidly growing city of Hyderabad, the Government of Telangana envisioned a transformative solution to alleviate congestion.

This led to the initiation of the Hyderabad Metro Rail Project, undertaken by L&T.

The primary objective was to provide the people of Hyderabad with a fast, reliable, and integrated mode of public transport.

The structures involved, such as diaphragm walls, precast segments, and deck slabs, required varying grades of concrete ranging from M-35 to M-45.

Sunanda Global’s Solution for the Hyderabad Metro Rail Project:

To meet the demanding requirements of the Hyderabad Metro Rail Project, Sunanda Global supplied its robust bipolar concrete penetrating corrosion inhibiting admixture.

This admixture, tailored for steel-reinforced concrete in corrosive environments, offered simultaneous cathodic and anodic protection to the steel.

Notably, it demonstrated high penetrating power, ensuring total protection of rebars and prestressed tendons.

Use in Hyderabad Metro Rail Project:

The Hyderabad Metro Rail Project extensively utilized Sunanda Global’s bipolar concrete penetrating corrosion inhibiting admixture.

The admixture was seamlessly incorporated into the concrete mix during the batching process, demonstrating its compatibility with other concrete admixtures.

This ease of integration allowed for flexibility, whether added at the concrete plant or on-site.

Advantages and Eco-Friendly Features:

The benefits of Sunanda Global’s admixture were manifold. Its ability to form a uni-molecular protective layer on the steel surface inhibited corrosion induced by chloride ions and concrete carbonation.

The admixture’s effectiveness in the presence of high chloride concentrations made it a suitable choice for marine zones, piers, piles, bridges, highways, and sewerage systems.

Additionally, being eco-friendly, nitrite, and chromate-free aligns with sustainable construction practices.

Seamless Integration with Construction Phases:

Sunanda Global’s bipolar concrete penetrating corrosion inhibiting admixture was not only instrumental in the construction of underground segments but also found applications in other critical elements of the project.

Its use in diaphragm walls, piling, and deck slabs showcased its versatility and reliability across various construction phases.

Positive Customer Feedback:

The outcome of the Hyderabad Metro Rail Project has left the customer highly satisfied.

Sunanda Global’s innovative approach and the superior performance of its admixture have contributed significantly to the project’s success.


The Hyderabad Metro Rail Project is a symbol of the effectiveness and reliability of Sunanda Global’s bipolar concrete penetrating corrosion inhibiting admixture.

As cities worldwide grapple with urbanization challenges, innovative solutions like these play a crucial role in ensuring the longevity and sustainability of vital infrastructure.

The success of this Metro Rail project reinforces the significance of collaborative efforts between technology providers and project contractors in achieving milestones in the realm of modern transportation systems.
