SikaInject®-501 AU

High-performance, two component polyurea silicate injection foam for cavity filling and ground consolidation.

SikaInject®-501 AU is a two component, solvent-free polyurea silicate based foam, engineered for rapid cavity filling and ground consolidation.

  • Stable and workable foam 
  • Very fast reacting material
  • Does not expand its volume when in contact with water.
  • Shows good adhesion to wet and low friction substrates.
  • Fire resistant (according to DIN4102-B2).

Application

Application steps

APPLICATION INSTRUCTIONS

SikaInject®-501 AU Part A and B are delivered ready to use. They are injected in the proportion of 1:1 by volume using a two component injection pump equipped with a static in-line mixer nozzle.
Please note: The curing reaction time is dependent on the temperature of the product and the ground. Please condition both components prior to application at a minimum temperature of 15°C.
To achieve an optimal mixing of the components during injection and cavity filling, the inclusion of a static in-line mixer in connection with the mixing head is strongly recommended. 

CLEANING OF TOOLS

For short breaks in the injection procedure, pump Part A through the in-line static mixer nozzle. After the injection process pump an appropriate cleaning and maintenance agent  (like SikaInject®-CL2) or oil containing no water, through the pump and injection hoses until SikaInject®-501 AU foam is completely washed out.
Store the pump and hoses with the cleaning agent inside and seal all openings.
