Sika® Inject-215
Sika® Inject-215 is a low viscosity, elastic polyacrylic injection resin with a fast, adjustable reaction time and high flexibility for the waterproofing of building structures.
- Adjustable pot life between 2 and 15 minutes
- Hydrophilic chemistry allows cured material to swell upon contact with water, providing additional seal properties
- Flexible and solvent-free acrylate resin
- Compatible with water
- Very good penetration
Usage
- Used for the injection of SikaFuko® injection hoses to seal construction joint.
- Used to seal water-bearing cracks and voids.
- Used for curtain/membrane injections in damp or water saturated ground conditions to waterproof large surface areas.
- Used as a post-construction, external injection sealing system for construction, and limited movement expansion or drainage pipe joints, that are, or will be, covered with damp or water saturated soil.
Advantages
- Adjustable pot life between 2 and 15 minutes
- Hydrophilic chemistry allows cured material to swell upon contact with water, providing additional seal properties
- Flexible and solvent-free acrylate resin
- Compatible with water
- Very good penetration

Swelling
Swelling behavior in demineralized water
Sika® Inject 215 has a medium to high swelling rate and therefore offers additional safety in case of movements/joint movements. The determination of the swelling rate depends of the contact medium, the temperature and reaction time.
Application
Mixing Ratio
Example for Mixing:
Ambient Temperature: +20 °C (68 °F)
Required Reaction Time: 5 minutes
Component A:
Accelerator quantity = 131 mL (4 1/2 fl. oz)
Resin = 7.57 L (2 US gal.)
Component B:
Hardener Powder = 1 bag
Water = 7.57 L (2 US gal.)
Please see chart above
Sika® Inject-215 consists of 3 components which can be mixed in dependance of the required reaction times:
- 7.57 L (2 US gal.) of the resin (Comp. A) are activated with 59 mL to 768 mL (2 fl. oz. to 26 fl. oz) of accelerator. The reaction time - see metering chart - is adjusted by the quantity of accelerator used.
- The hardener solution (Comp. B) is produced by dissolving 1 bag (396 g (14 oz.)) of hardened powder in 7.57 L (2 US gal.) of water.
- The pre-mixed components as per point 1 and 2 above are processed with a two component injection pump, having a static mixing unit in a mixing ratio of 1:1.

NOTES ON INSTALLATION
Processing
Injection with two-component pump via injection hoses or drill packer
SUBSTRATE PREPARATION
Substrate Temperature: Minimum: +5 °C min. / Maximum: +40 °C
CLEAN UP
Sika® Inject-215 is compatible with water, therefore re-injectable injection hoses can be cleaned by vacuum. Tools and injection pumps can be cleaned with water after use. Hardened/cured material can only be removed mechanically.
