Sika® Grout Aid

Expanding, water-reducing, retarding high-lift grouting aid

Sika® Grout Aid is a balanced blend of expanding, retarding, and water-reducing agents for Portland cement grouts. It provides a slow, controlled expansion prior to the grout hardening.

  • A water reduction of at least 10 % is typical with the use of Sika® Grout Aid.
  • Expansion action largely compensates for loss of grout volume.
  • Increased water retention extends length of time that grout remains plastic so it may be vibrated.
  • Allows for leaner mix.
  • Superior place-ability and expansion in-place reduces cracks and cold joints.
  • Retardation of setting time allows a longer period of time for expansive action to take place.
  • Higher shear and bond values.
