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
|

Packaging Part A | 9,9 kg | Part B | 12 kg |
Refer to current price list for packaging variations. Colour Part A: | yellowish | Part B | brown | Part A+B mixed | ~ amber | |
Technical Information Compressive Strength ~70 N/mm2 (7 days / +21 °C) | (ISO 604) |
Tensile Strength ~30 N/mm2 (7 days / +21 °C) | (ISO 527) |
Chemical Resistance Resistant to salts, alkali and acids present in construction components or in the ground. Contact Sika Technical Services for additional information. |
Application Information Mixing Ratio A : B = 1 : 1 parts by volume A : B = 1 : 1,2 parts by weight Substrate Temperature > +1 °C Pot Life Temperature | Time | +10 °C | ~50 minutes | +20 °C | ~25 minutes | +30 °C | ~10 minutes |
The pot life begins when Parts A+B are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. To obtain longer workability at high temperatures, chill Parts A+B before mixing (not below +5 °C). |
