Structural polyurethane injection resin

Sika Injection-216 is a 2-part, polyurethane structural injection resin. It is specially formulated for crack injection work by pressure injection.

  • Very good adhesion to concrete, masonry and stone.
  • Suitable for dry, damp and wet conditions
  • Very high mechanical properties
  • Fast curing with or without water contact
  • Reaction time adjustable with accelerator
  • Injectable with 1-component or 2-component pumps
  • Compatible with concrete, mortar, metal, plastic coated components, cable coatings, etc.
  • Resistant to salts, alkali and acids present in construction components or in the ground
  • Prevents the ingress of water and infiltration which can cause reinforcement corrosion
Usage
