The reservoir faced significant structural and safety challenges, including spalled concrete, failed sealant joints, and large voids that compromised its integrity and waterproofing. Additionally, the roof contained asbestos fiber cement sheets, posing health and environmental risks if disturbed. The floor surface was also deteriorated, requiring a durable and waterproof solution to ensure long-term functionality and compliance with potable water standards.
To address these issues, spalled concrete was repaired, and failed sealant joints were replaced to restore structural integrity. Larger voids and transitions were rebuilt using Eucocrete HBM, creating smooth coved transitions, while Eucocrete NWP filled smaller imperfections and provided a waterproofing layer for optimal coating adhesion. Movement joints were sealed with Dymonic 100, a potable water–certified sealant. The asbestos-containing roof was safely encapsulated with Altex Encapsulation Primer, sealed with Dymonic 100, and topcoated with Carboguard 636 PW. The floor was resurfaced with Versaspeed LS100 and finished with Carboguard 636 PW, resulting in a durable, waterproof, and uniform finish.
