Hindon Elevated Road’s Background:
The Hindon Elevated Road, spanning 10.3 kilometers, is the longest elevated road in India, connecting Raj Nagar Extension to UP Gate at the Delhi border.
Built for Rs. 1,147 crores, the road features 228 single-pier pillars and facilitates seamless connectivity to NH-24, also known as the Delhi–Meerut Expressway.
Challenges for the Hindon Elevated Road project:
Firstly, the sheer scale of the 10.3-kilometer road demanded meticulous planning to ensure uniform coating application. The project faced weather variability, including heavy rainfall, high humidity, and extreme heat, requiring adaptive strategies for consistent quality amid diverse climatic conditions.
Ensuring consistency in coating application across the 228 single-pier pillars and adopting advanced coating technology presented additional hurdles.
Vigilance is required to maintain high standards throughout the application process due to strict quality control measures. Meeting project deadlines, especially in the face of unexpected challenges, demanded proactive problem-solving and efficient project management to avoid financial penalties or disruptions to traffic flow.
To face these challenges, the project team and contractors chose Sunanda Global’s anti-carbonation coatings.
Application Process:
The Hindon Elevated Road project incorporated a meticulous approach to applying Sunanda Global’s anti-carbonation coatings.
The process began with a thorough surface preparation and cleaning, recognizing that the life and performance of the coating depend on the extent and quality of cleaning.
Surface examination revealed cracks and openings, which the contractors diligently filled with a polymer-modified mortar. Removing scales, rust, and grease was imperative in the case of steel surfaces.
The applicators team used brushes, rollers, or spray equipment to apply the chosen anti-carbonation coatings. The application process involved two to three coats, with a minimum interval of 4-6 hours between successive coats.
During the application and setting period, the contractors took stringent measures to protect the coating from dust, dirt, and grease.
Benefits of Sunanda Global’s Anti-Carbonation Coatings:
A myriad of advantages drove the decision to utilize anti-carbonation coatings for the Hindon Elevated Road project:
Protection against Environmental Attacks: These coatings shield external surfaces from carbonation and other environmental assaults, ensuring the structure’s longevity.
Durability and Long-Lasting Finish: The coatings provide a durable and aesthetically pleasing finish, capable of withstanding extreme climatic changes, including heavy rainfall, high humidity, and heat.
Prevention of Water Leakages: The coatings, acting as a barrier, prevent water leakages and dampness, safeguarding the structure’s integrity.
Thermal Insulation: The coatings prevent a rise in internal temperature, enhancing the comfort and safety of the infrastructure.
Crack Resistance: Unlike conventional coatings, Sunanda’s protective coatings do not peel or crack, ensuring a continuous protective layer.
Increased Service Life: By preventing the carbonation of concrete, these coatings significantly increase the total service life of the structure, leading to reduced maintenance costs over the years.
Resistance to Fungi and Algae: The coatings prevent the formation of fungi and algae, maintaining a freshly painted appearance for an extended period.
UV Stability: With excellent UV stability, the coatings resist degradation from prolonged sun exposure, contributing to long-term performance.
Conclusion:
The successful application of Sunanda Global’s anti-carbonation coatings on the Hindon Elevated Road is a testament to the efficacy of the advanced protective solutions.
The decision to fortify the external walls with these coatings proved instrumental in enhancing the road’s durability, safety, and aesthetic appeal.
The careful selection of coatings, meticulous application processes, and adherence to high-quality standards resulted in a resilient infrastructure that will serve the community for years to come.
This case study highlights the transformative impact of anti-carbonation coatings in infrastructure projects, emphasizing the importance of forward-thinking solutions for sustainable and enduring structures.
