SUBSTRATE PREPARATION
 

The substrate must be sound, clean, free of oil and grease, old coatings and other contaminations.
 

For good adhesion, pre-treat the substrate with high pressure water or mechanically.
 

Use air pressure to remove dust from cracks.
 

MIXING
 

Place the liquid part B in a suitable mixing vessel. Mix with colloidal mixer at a minimum 2 800 rpm and add the powder part A slowly and continuously. Mix the suspension thoroughly for at least 5 minutes.
 

Subsequently, pour the injection material directly into the pump or keep ready in a clean container.
 

APPLICATION METHOD / TOOLS
 

The injection material can be injected with commercially available equipment designed for cement injections (injection pressure 3 - 8 bar).

Start injecting at low pressure and build as necessary.
 

For vertical injection sections, inject from bottom to top.

If dry concrete has to be injected, it is recommended to pre-wet the concrete with water under light pressure.
 

In order to enable post-injections, the freshly injected section of the SikaFuko® systems (or the injection packers) must be thoroughly rinsed.

CLEANING OF TOOLS
 

Clean tools with water immediately after use.
Hardened material can only be removed mechanically.
