Underground Garage Waterproofing – New Belgrade Case Study

Persistent Basement Leakage Threatening Operations

A multi-level underground parking garage in New Belgrade faced persistent water ingress due to:

• High groundwater pressure in the river-adjacent zone,
• Settlement-induced cracking in slabs and retaining walls,
• Failing conventional waterproofing membranes,
• Ongoing moisture problems causing:
  • Standing water on parking surfaces,
  • Dampness damaging stored property,
  • Risk of corrosion in embedded steel reinforcements,
  • Tenant complaints and increased maintenance costs.

Due to the facility’s continuous use, a fast, non-invasive sealing solution was needed to avoid operational disruption.

EURAS® Gel Type B – Elastic, Non-Toxic Waterproofing

Following assessment, EURAS® Gel Type B was chosen because it:

• Penetrates and displaces active water in saturated cracks,
• Remains elastic and adherent even under movement,
• Is compatible with old concrete and residual moisture,
• Can be applied by high-pressure injection without excavation.

The project was executed during scheduled maintenance intervals:

1. Mapping infiltration points with moisture sensors and inspections,
2. Drilling injection ports along perimeter walls and floor slab cracks,
3. High-pressure injection of EURAS Gel Type B up to 130 bar,
4. Continuous monitoring of flow reduction and gel return to confirm saturation,
5. Final inspection and verification of watertightness.

All work was performed without closing the garage to residents or tenants.
