Silane based reactive water repellent impregnation.

Sikagard®-705 L is a one-component low viscosity, solvent free, reactive impregnation for concrete and cementitious substrates based on silane with 99 % active ingredient. Sikagard®-705 L complies with the highest requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class II & resistance to freeze and thaw salt stresses).


Sikagard®-705 L is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as concrete in civil engineering or building concrete structures subjected to heavy stress due to freeze and thaw cycles and de-icing salts and chloride attack in marine environment
  • Suitable for protection against ingress (Principle 1, method 1.1 of EN 1504-9),
  • Suitable for moisture control (Principle 2, method 2.1 of EN 1504-9)
  • Suitable for increasing the resistivity (Principle 8, method 8.1 of EN 1504-9)


  • Excellent penetration
  • Fast uptake even on dense concrete
  • Economic and easy to use
  • Reduces capillary water absorption, protection against driving rain and splashing on vertical areas
  • Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment)
  • No change in water vapour permeability
  • Long term efficiency, deep penetration
  • Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
  • Reduce corrosion even in cracked concrete
  • Retard corrosion initiation by reducing the available humidity at reinforcement bars level
  • Mitigate corrosion by preventing further chloride to migrate to reinforcement bars
  • Comply with Dutch guidelines (RWS NEN-EN 1504-2) on CEM III
  • Resistant to sea water
  • Low VOC content
  • Ready to use
