We have taken care to work with capillary-breaking systems that stop the pores from being sucked in and bond inseparably with the building material.
HydroBloc SI 709 is solvent-free you only need one material for all degrees of moisture penetration.
This means no matter how wet the wall is Si 709 is the right material.
So you reduce storage and capital tie-up. We use water as a transport medium to bring the active reactive SIloxane into the structure.
HydroBloc Diffusion 715 is full cream power and ready to use.
It comes in a handy bucket for application with a hand pump or in a cartridge for clean fast working.
Why Diffusion 715 is so special is easily explained.
It contains no blending agents and above all no water, so you can also use normal steel pumps without it leading to corrosion.

Which water repellent is best used where

The building material, the degree of moisture penetration, further damage, etc. are different on every construction site.
To ensure that you always have the right product, we have taken care to develop products for all degrees of moisture penetration that you can easily adapt to your project.
The main differences lie in the way the material is placed or applied. This is where your personal preference comes into play. Do you prefer to work with creamy products or with liquid ones?
Both systems deliver perfect results.
