SikaInject®-567

Highly Reactive, 2-C Polyurea Silicate Injection Foam

SikaInject®-567 is a 2-component, solvent-free polyurea silicate foam specifically designed for rapid cavity filling and ground consolidation

  • Very fast reacting material
  • Stable and workable foam structure
  • Does not expand its volume on contact with water
  • Shows good adhesion to wet and low friction substrates
  • Fire resistant (acc. to DIN 4102-B2)
  • Cured foam is cuttable (e.g. by TBM or coal planners)

Application steps

MIXING

Part A and part B are delivered ready to use. Inject them in mixing ratio of 1:1 parts by volume using a 2-component injection pump equipped with a static in-line mixer nozzle. For optimal mixing of the components use a min. 32 cm static-in-line mixer in connection with the mixing head. 

CLEANING OF TOOLS

  • For short breaks in the injection procedure, pump part A through the in-line static mixer nozzle

  • After the injection process rinse pump with suitable cleaning agent (e.g. SikaInject®-CL2) or water-free low-viscosity hydraulic oil

  • Flush pump and injection hoses until SikaInject®-567 is completely washed out

  • Store pump and hoses filled with oil and seal all openings
