Basement Leak Sealing at King’s Court – Belgrade, Serbia

Chronic Leakage in High-Value Residential Basement

King’s Court is a premium residential and commercial complex in the center of Belgrade. Over time, continuous water ingress developed in the underground parking and storage levels due to:

• Hydrostatic pressure from high groundwater levels,
• Settlement-induced micro-cracking in basement slabs and walls,
• Deterioration of prior waterproofing layers,
• Moisture intrusion affecting property value and tenant satisfaction.

The leaks led to:

• Standing water and dampness in basement zones,
• Risk of mold and structural deterioration,
• Tenant complaints and reputational concerns,
• Limited access for traditional sealing methods without extensive demolition.

EURAS® Gel Type B – Non-Invasive, High-Performance Waterproofing

After site evaluation, EURAS® Gel Type B was selected for its:

• Hydroscopic properties that absorb and displace water in saturated cracks,
• Elasticity to accommodate settlement and thermal expansion,
• Compatibility with aged concrete and old waterproofing membranes,
• Capacity for deep penetration via high-pressure injection.

The project was carried out with minimal disruption to residents and property operations:

1. Identification and mapping of active leak points and micro-crack zones,
2. Drilling injection ports in targeted areas across the basement walls and floor slab,
3. High-pressure injection of EURAS Gel Type B up to 120 bar for deep cavity saturation,
4. Continuous monitoring of gel flow and back-pressure,
5. Post-injection verification of watertightness.

• elimination of active leaks,
• Dry, clean basement conditions restored,
• Protection of the structure against further moisture damage,
• Improved tenant satisfaction and property value,
• No need for extensive demolition or reconstruction.
