Sealing Stormwater Tanks For A Dublin Data Center

HydraTite® (Internal Joint Seal System)

Stormwater

Challenge
A Dublin Data Center faced significant issues with six stormwater retention tanks, which were experiencing multiple leaking points, some of which were gushing. Previous repair attempts had failed, with repairs buckling and no longer firmly pressing against the interior tank walls. Inspection revealed some joints were separated, and previous repairs had begun to corrode.  The leaks threatened the integrity of the stormwater management system, risking operational disruptions and potential environmental concerns. The client did not wish to dig and replace, but the need for a reliable, long-term solution was critical to restore system functionality and prevent further deterioration.

Engineered Solution

The project utilized HydraTech’s HydraTite Internal Pipe Joint Seals to address the leaking joints in the stormwater retention tanks. Specifically, 42 standard-wide and 3 extra-wide HydraTite seals were custom-fabricated for the 94.5” corrugated steel circular pipes, as this size was not part of HydraTech’s standard inventory. Each seal was secured with three retaining bands to ensure a tight, durable fit. For areas with less extensive damage, gel injections were employed as a repair method to address minor compromised points, providing a comprehensive approach to the restoration.

Scope

Solution

The installation of the custom HydraTite Internal Pipe Joint Seals and gel injection successfully functioned as a trenchless solution eliminating the need for disruptive excavation or pipe replacement— saving the client time, cost, and future risk. The system is now fully operational, ensuring reliable stormwater management for this Dublin Data Center. The durable, long-term repair solution prevented further water loss and environmental risks, while the custom fabrication and efficient installation process saved the customer significant time and cost compared to alternative replacement options. The project was completed on schedule, meeting all performance expectations and providing a robust, lasting solution.
