ESSRBOND GS500: Precision Engineered for Performance.

1. About ESSRBOND GS500: Precision Engineered for Performance.

ESSRBOND GS500 is a single-component, water-reactive polyurethane grout designed for high-performance crack sealing, leak arresting, and waterproofing applications. Engineered for an exceptional hydrophobic response, GS500 reacts instantly upon contact with water, expanding into a closed-cell, rubber-like foam that expands up to 27 times its original volume, forming a resilient and long-lasting seal.

2. Why Choose ESSRBOND GS500 Over Traditional Grouting?

• No Shrinkage or Swelling: Unlike water-based systems, GS500 retains constant volume after curing.
• Not Affected by Wet/Dry Cycles: Performs in harsh conditions, whether exposed to constant moisture or complete dryness.
• Flexible Application: Reacts to form either dense gel or foam, depending on injection pressure.
• No Water Dependency: Foam structure is independent of ambient water content, ensuring stability.

3. Technical Features & Benefits: The ESSRBOND GS500 Advantage

Feature	Technical Benefit
Hydrophobic Polyurethane Base	Long-term water resistance and leak-proof sealing.
Closed-Cell Foam Reaction	Expands up to 27x to fill fine cracks and voids.
No Volume Loss	Maintains structural integrity without post-cure shrinkage.
Adjustable Density	Can form flexible foam or dense seal based on pressure.
Long-Lasting & Durable	Withstands hydrostatic pressure and aggressive environments.
Non-Shrinking & Non-Swelling	Maintains dimensional stability over time.

4. Where You Can Use ESSRBOND GS500

• Basement and Tunnel Crack Sealing.
• Active Water Leak Arrest in Retaining Walls.
• Expansion Joint Waterproofing.

5. Performance Benchmarking: ESSRBOND GS500 vs Traditional Injection Grouts

Parameter	ESSRBOND GS500	Traditional Grout
Water Resistance	High (Hydrophobic)	Moderate (water-reliant)
Reaction Time	Rapid with water contact	Slow or inconsistent
Post-Cure Stability	Excellent (No swelling or shrinkage)	May swell/shrink
Versatility in Density	High (Foam or Gel)	Fixed
Durability in Harsh Zones	Excellent	Variable

6. Sustainability & Safety Compliance

• VOC-Compliant: Environmentally safer and green-building friendly.
• Zero-Solvent Emission: Safe for use in confined, sensitive areas.
• Sustainable Packaging: Aligned with eco-conscious construction practices.

7. Strategic Recommendations for Engineers & Contractors

• Inject Early: Use GS500 for pre-leak and active crack treatment.
• Train Your Teams: Hands-on injection best practices enhance results.
• Include in Specifications: Ensure long-term waterproofing is built in, not added later.
• Leverage Technical Support: ESSRBOND offers onsite training, trials, and consultation.

8. Conclusion: Seal the Future with Confidence

Whether you’re restoring aging infrastructure or protecting new foundations, ESSRBOND GS500 is your partner in long-term waterproofing and structural integrity. Smart chemistry, easy application, and guaranteed performance—this is the future of hydrophobic grouting.
