Chronic Leakage in Potable Water Infrastructure

The Hoch-Behälter is a critical potable water reservoir supplying the Usingen region in Hesse, Germany. Over time, persistent leaks developed in:

• Construction joints between the reservoir walls and floor slab,
• Microcracks formed due to settlement and thermal cycles,
• Interfaces between old concrete and rehabilitation sections.

This led to:

• Uncontrolled water loss, reducing storage capacity,
• Risk of contamination from surrounding groundwater,
• Moisture-related degradation of reinforcement,
• Regulatory compliance issues for drinking water safety.

Due to the reservoir’s essential role, a non-toxic, non-invasive repair solution was required without emptying or replacing the structure.
