Signia by Hilton Atlanta Georgia World Congress Convention Center is a new high-rise hotel in the heart of Atlanta, Georgia. This world-class hotel is connected to the Georgia World Congress Center and features 94 rooms, six bars and restaurants, a wellness center, a book room, and an outdoor pool. It’s conveniently located near Mercedes-Benz Stadium, Georgia Aquarium, State Farm Arena, the College Football Hall of Fame, and other popular attractions – making it a convenient hub for visitors and convention-goers.
The Challenge: Ensuring Eco-Conscious Water Containment
To meet the property’s water needs for fire suppression and irrigation systems, an eco-conscious and durable water containment solution was required. Hydrona LLC, a Dallas/Fort Worth-based waterproofing company, was brought on board to address this challenge. Known for its expertise in designing and implementing rainwater harvesting systems, fire suppression tanks, well water storage tanks, and biological wastewater treatment tanks, Hydrona offers a comprehensive approach to water storage solutions.
From pre-build consultation to fully custom-designed turnkey systems, Hydrona does it all. In addition to developing water tanks, Hydrona rehabilitates and extends the life of existing tanks and new tanks by adding lining systems that prevent corrosion.
Hydrona’s task was to rehabilitate and line two massive water tanks, each holding 300,000 gallons, with dimensions of approximately 39 feet in diameter and 24 feet in height. The lining had to meet stringent deadlines to ensure the hotel opened as scheduled. The project demanded a high-performing waterproofing solution that could be applied quickly and withstand significant mechanical and chemical stress over time.
The Solution: Polyglass Tecnocoat Polyurea Coatings Waterproofing System
To meet these needs, Hydrona chose Polyglass USA‘s Tecnocoat P-2049, an advanced pure polyurea membrane. This innovative, two-component, fast-curing system is designed for exceptional performance in waterproofing and traffic coating applications.
The application process utilizes a hot spray method, ensuring consistent thickness and optimal adhesion. Furthermore, the use of plural-component spray equipment enables accurate application on both vertical and curved surfaces, allowing skilled installers to achieve the required thickness effectively in a single pass. Tecnocoat P-2049 offers the following technical features and benefits:
Fast Curing: The spray-applied polyurea system cures quickly, enabling the tanks to be operational and filled with water within just 48 hours. This accelerated timeline marks a substantial advancement compared to conventional epoxy systems, which usually demand multiple coats and prolonged drying periods before they can be put back into service.
Dry Film Thickness (DFT): Tecnocoat P-2049 was applied at a thickness of 100 mils, significantly surpassing the 22 mils typical of standard epoxy coatings. This greater thickness improves the system’s durability and resistance to environmental stressors. Unlike traditional epoxy, which requires multiple coats with extended drying times between applications, Tecnocoat P-2049 achieves the desired thickness in a single application.
Exceptional Elongation: Tecnocoat P-2049 boasts an elongation rate of 500%, far exceeding the 4% offered by epoxy coatings. This exceptional flexibility greatly minimizes the risk of cracking, helping the coating maintain its integrity over time and effectively preventing corrosion beneath the membrane.
Chemical and Mechanical Resistance: The product demonstrates exceptional resistance to harsh chemicals and mechanical stress, making it ideal for long-term water containment.
Longevity: With a life expectancy of over 30 years, the Tecnocoat system offers triple the lifespan of epoxy coatings, delivering a more cost-effective solution in the long term. The impressive chemical resistance of the Tecnocoat system ensures it withstands heavy mechanical and chemical loads over time.
Seamless Application
The seamless, fully bonded nature of Tecnocoat’s spray-on application was another key factor. The monolithic membrane eliminates potential weak points where water ingress might occur. This feature is particularly crucial for large-scale tanks, as it ensures uniform coverage and minimizes maintenance needs over the product’s lifetime.
Results
The application of Tecnocoat P-2049 delivered extraordinary results. The project was completed in record time, meeting all performance and durability requirements. The seamless application process ensured rapid curing and immediate readiness for use. The Hydrona team, the hotel contractor, and the property owner were thrilled.
“Once the general contractor and owner were made aware of the benefits of TecnoCoat Polyurea over epoxy, especially regarding water storage, they quickly decided to move forward with the system,” shared Jacob Hannasch of Hydrona LLC. “They were surprised the cost was similar for 100 mils of polyurea vs 22 mils of epoxy. And they were very pleased with the outcome and could not believe how fast the material cured and the tanks could be put into service.”
