Sika® Intraplast® N

Sika® Intraplast® N

Expanding / Fluidifying Grouting Aid

Sika® Intraplast® N is a balanced blend of expanding, fluidifying, and water-reducing agents for Portland-cement grouts. It produces a slow, controlled expansion prior to the grout hardening.

  • High fluidity - Sika® Intraplast® N grout is extremely fluid, workable, non-settling, and cohesive.
  • Versatile - use Sika® Intraplast® N with all types of grout incorporating Type I, II, or III cement, with or without pozzolanic materials or fly ash, and with or without fine aggregate.
  • Controlled, gaseous expansion occurs before initial set and forces the grout into close contact with the surrounding surfaces.

Application steps

MIXING

  • Water should be added to the mixer first, followed by Portland-cement, fly ash, admixture, and sand as required.
  • Mixing should be of such duration as to obtain a uniform, thoroughly blended grout, without excessive temperature increase.
  • No water should be added to the grout to increase any flowability which has been lost by delayed use of grout.
  • It is essential that the water content of the grout be kept as low as possible.
  • The water content should generally be less than 5.25 gal/100 lb of cementitious material.
  • Do not overwater!
