Hydrophobic fumed silica in cement-based waterproofing

The role of hydrophobic fumed silica in cement-based waterproofing

✅ Increases waterproofing ability
- Hydrophobic silica creates a "water-beading" effect on the surface.

- Helps create a hydrophobic network in the microstructure of the cement layer after curing.

✅ Reduces capillary water absorption
- Disrupts the capillary system in the cement base, thereby reducing the ability to absorb moisture back.

✅ Increase durability and stability
- Helps improve the stability of polymer emulsions if used in 2-component waterproofing systems (polymer-cement).

- Reduces the deposition of solid particles in the mixture.

✅ Improves construction
- Slightly increases viscosity, helping the material adhere better to vertical surfaces (such as walls, columns).

- Helps the mixture to be anti-sagging without affecting the flowability too much.

When using hydrophobic fumed silica for cement-based waterproofing materials, attention must be paid to the viscosity and pH of the cement base to achieve effective use. For more details on hydrophobic fumed silica used in cement-based waterproofing, please contact the following information:
