Product Description

XD-01 is a hydrophilic one-component foaming polyurethane. It reacts rapidly with water, expands quickly, and seals cracks to achieve water stopping. It can also be used with a small amount of catalyst to adjust foaming speed according to actual construction needs.

Advantages

1. 1.Low viscosity, no clogging in high-pressure injection hoses during operation; easy to construct with excellent workability.
2. 
   
3. 2.Excellent water miscibility, reducing residual water inside cracks that may damage the foam and cause secondary leakage.
   
4. 
   
5. 3.High reactivity: gels and solidifies in approximately 20–120 seconds upon contact with water.
   
6. 
   
7. 4.Good stability: remains usable after opening within construction time; unopened product can be stored for more than 6 months without deterioration.
   
8. 
   
9. 5.Strong adhesion to concrete, no delamination.
   
10. 
    
11. 6.Compatible with slightly acidic, alkaline, or seawater environments without affecting physical and chemical properties of the foam.
    
12. 
    
13. 7.High structural strength and toughness, with long-term water resistance.
    

Disadvantages

1. 1.Low shrinkage, but secondary leakage may occur if cracks are not fully filled.
   It is recommended to inject 2–3 more times after the first foaming to fill internal voids and reduce dry shrinkage.
2. 
   
3. 2.Foaming expansion ratio: about 15–20 times. It can be blended with hydrophobic products to increase expansion ratio.
   

Curing Characteristics

1. 1.The cured expanded material resists weak acids and weak bases, and is compatible with asphalt joint fillers, concrete, etc.
2. 
   
3. 2.XD-01 one-component waterstop is especially suitable for below groundwater level applications due to its long-term water resistance and hydrophilicity.
   

Application Scope

1. 1.Filling dry and wet cracks in concrete components, achieving full contact bonding.
2. 
   
3. 2.Stopping water leakage.
   
4. 
   
5. 3.Sealing wet construction joints.
   
6. 
   
7. 4.Injecting cracks with underground water pressure; can be used with catalyst to form foam within 3 seconds and fully expand and solidify within 2 minutes after contacting water.
   

Product Features

1. 1.Reacts immediately upon contact with water, encapsulates water, expands and solidifies.
2. 
   
3. 2.Low expansion ratio, high toughness.
   
4. 
   
5. 3.Strong adhesion to substrates; good chemical resistance (potable water, seawater, wastewater, diluted acidic/alkaline chemicals).
   
6. 
   
7. 4.Non-toxic after full reaction.
