Leak Sealing at Episkopi Desalination Plant – Cyprus

Persistent Water Ingress in Critical Water Treatment Infrastructure

The Episkopi Desalination Plant is a vital facility providing potable water to coastal Cyprus. Over time, the plant developed chronic leakage in:

• Underground service galleries,
• Construction joints between slabs and walls,
• Microcracks in the concrete exposed to saline and aggressive water.

The leaks created:

• Standing water in confined maintenance areas,
• Corrosion risk to equipment and structural reinforcements,
• Potential contamination concerns in sensitive treatment zones,
• Access constraints preventing conventional repair solutions.

Due to the plant’s critical role in regional water supply, a fast, non-disruptive repair method was required.

EURAS® Gel Type B – Sealing Leaks Under Saline Conditions

After technical assessment, EURAS® Gel Type B was selected because of its:

• Hydroscopic swelling action to displace water in live leaks,
• Elasticity and adhesion to withstand settlement and vibration,
• Compatibility with saline water exposure,
• Deep penetration capacity through high-pressure injection.

The sealing was performed during scheduled maintenance without interrupting plant operations:

1. Mapping infiltration areas in the galleries and interfaces,
2. Drilling injection ports to target crack networks,
3. High-pressure injection of EURAS Gel Type B up to 150 bar,
4. Monitoring gel flow and back-pressure to confirm saturation,
5. Verification of watertightness and structural integrity.
