Case study of Indian Institute of Science Education and Research in Tirupati – Hybrid Polyurea Waterproofing

Introduction to Indian Institute of Science Education and Research (IISER) Tirupati in Andhra Pradesh:

India’s Ministry of Education has founded seven Indian Institutes of Science Education and Research (IISERs).

The following locations host the institutes:

  • Berhampur
  • Bhopal
  • Kolkata
  • Mohali
  • Pune
  • Thiruvananthapuram
  • Tirupati
The IISERs uniquely integrate teaching with advanced research, fostering curiosity and creativity in a vibrant academic atmosphere.

Each  Indian Institute of Science Education and Research (IISER) is autonomous and awards its own Bachelor, Master, and Doctoral degrees.

IISER Tirupati, the sixth institution in the IISER network, offers high-quality education in basic sciences alongside advanced research amenities.

Academic activities at IISER Tirupati commenced in August 2015 at the spacious Sree Rama Engineering College transit campus.

IIT Tirupati is located a mere 3 kilometers away along this road.

The establishment of IISER and IIT in Tirupati facilitates a unique synergy between two premier educational institutes.

The institute plans to move to its permanent campus at Srinivasapuram and Panguru village on the Yerupedu-Venkatagiri Road, which will offer state-of-the-art research facilities.

Ensuring the longevity and security of the building surfaces was crucial for safeguarding these critical infrastructures.

This is where Sunanda Global’s hybrid polyurethane elastomeric waterproofing coatings played a crucial role.

Need for Waterproofing Solutions:

The Indian Institute of Science Education and Research (IISER) Tirupati project required a robust waterproofing solution to safeguard its concrete structures from harsh environments.

Given the region’s climatic conditions, the institute’s external surfaces needed protection against water ingress, UV radiation, and thermal variations.

Sunanda Global’s hybrid polyurethane elastomeric waterproofing coatings proved optimal for their performance and easy application.

Project Execution for Indian Institute of Science Education and Research (IISER):

Support Preparation

The initial stage of the project prioritized preparing concrete surfaces for optimal waterproofing adhesion.

This involved:

Surface Milling:

The project crew milled the concrete slabs to create a rough surface that enhances the bonding of the waterproofing membrane. This step eliminates air pockets and prevents the formation of bubbles or craters.

General Cleaning:

They used vacuum equipment to remove dust, dirt, and other contaminants to ensure a clean substrate for the waterproofing application.

Addressing Singular Points:

The project team gave special attention to the unique structural elements such as expansion joints, wall intersections, and drainage points.

The team treated these areas meticulously to ensure the seamless application of the waterproofing membrane.

This approach helps prevent membrane damage due to structural movements over time.

The project team applied superbly, ensuring flexibility and durability and accommodating potential structural movements.

Application of Hybrid Polyurethane Elastomeric Waterproofing Coatings for Indian Institute of Science Education and Research (IISER) project in Andhra Pradesh:

The project applicators applied hybrid polyurethane elastomeric waterproofing coatings in stages, ensuring a lasting, continuous protective layer.

Priming

Primer Application: The applicators applied a specialized primer over the entire surface to enhance adhesion and prevent air entrapment. This primer ensured a strong bond between the concrete substrate and the waterproofing membrane.

Membrane Application:

The applicators applied a hybrid polyurethane elastomeric membrane using advanced spraying equipment.

This equipment allowed precise control over the mixture, temperature, and pressure, ensuring a uniform application.

They applied multiple continuous layers until they achieved the required thickness, as specified by industry standards.

Advantages of Using Hybrid Polyurethane Elastomeric Waterproofing Coatings for Indian Institute of Science Education and Research (IISER) project in Andhra Pradesh:

Several significant advantages prompted the decision to use Sunanda’s hybrid polyurethane elastomeric waterproofing coatings:

Seamless Application: The coatings provided a seamless and monolithic membrane, crucial for ensuring complete waterproofing across the entire surface, including complex intersections and vertical walls.

Durability and Flexibility: The hybrid coatings offered excellent resistance to abrasion, punctures, and UV radiation. Their flexibility allowed them to accommodate structural movements without cracking or delaminating.

Enhanced Protection: The coatings created a tough barrier against moisture, oxygen, and chlorides, significantly extending the lifespan of the reinforced concrete structures.

Versatility: These coatings, ideal for diverse environmental conditions, were ideal for the IISER Tirupati project’s varied needs.

Quick Turnaround: The hybrid polyurethane coatings cure quickly. This reduced project downtime and expedited the completion of waterproofing.

Conclusion:

Sunanda Global’s hybrid polyurethane elastomeric waterproofing coatings at IISER Tirupati effectively shielded critical infrastructures from environmental elements.

The robust application process, along with the superior coatings, ensured a durable waterproofing solution.

IISER Tirupati utilized advanced waterproofing technologies, ensuring its buildings endure over time and serve scientific excellence.
