Sika® Injection-127 H

Hydrophobic Polyurethane Foam for Crack Injection

Sika® Injection-127 H is a water-activated hydrophobic polyurethane injection grout designed to stop water leakages.

  • Low viscosity offers superior penetration through narrow or hairline cracks
  • Variable reaction time allows to be used in broad range of applications
  • Expand up to 30 times of the original volume
  • Closed and fine cell foam results in best waterproofing ability
  • Seal cracks quickly and efficiently
  • Cured material not affected by water or dryness
  • Flexible and good adhesion to concrete
  • Non-toxic once in cured form

Application steps

SUBSTRATE PREPARATION

All surfaces must be free from oil, grease, dirt and poorly adhering matter.

MIXING

Mix Sika® Injection-127 H part A (Resin) with part B (Catalyst) using the typical ratio 10:1. However, the amount of accelerator maybe increased or decreased as needed based on job site condition. Mix by stirrer until the chemical appeared homogeneous.

CLEANING OF EQUIPMENT

Tools and equipment must be cleaned immediately after use. Packers can be removed within one hour and the holes should be patched.
