Water-triggered polyurethane resin that self-emulsifies into elastic gel, sealing active leaks with CO₂-driven expansion pressure.
3Minute Water Stop -Gel time ≤180s with 10x water.
CO₂-Powered Expansion - 350% foaming rate forces resin into voids.
Flow Through Resistance - Won't wash out under 15L/min flow.
One Part Simplicity - No mixing; activates on water contact.
Structural Flexibility - 30% elastic recovery after movement.

Product Usage
Three Zhanghewan Dam Seepage Control Project
When 20L/min leaks threatened dam stability:
00:00 - Resin injected at 3MPa pressure
00:45 - CO₂ expansion initiated → 350% volume increase
03:00 - Elastic gel formed → leakage reduced by 98%
24h - Full cure achieved (0.9MPa adhesion to wet concrete)
Drill at 45° angle toward water source
Maintain ≥15MPa injection pressure
Space ports at 20-30cm intervals
Never inject against water flow
Don't exceed 40°C substrate temperature
| Scenario | Technique | Performance Data |
| Tunnel Gushing | Upstage grouting | Stops 25L/min flow |
| Basement Joints | Curtain injection | Seals 5mm cracks |
| Pipe Penetrations | Annular space filling | 0.6MPa adhesion |
