Injection Systems - Sika® Inject-215

Elastic Polyacrylic Injection Resin Used for Permanent Watertight Sealing

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

• Sika® Inject-215 is used for the injection of SikaFuko® injection hoses to seal construction joint.
• Sika® Inject-215 is used to seal water-bearing cracks and voids.
• Sika® Inject-215 is used for curtain/membrane injections in damp or water saturated ground conditions to waterproof large surface areas.
• Sika® Inject-215 is 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

Technical Information

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

Application Information

Mixing Ratio

Example for Mixing:

Ambient Temperature 20^oC (68^oF)

Required Reaction Time 5 min.

Component A

Accelerator quantity = 4 1/2 fl. oz

Resin = 2 gallons

Component B

Hardener Powder = 1 bag

Water = 2 gallons

Sika® Inject-215 consists of 3 components which can be mixed in dependance of the required reaction times:

1. 2 gallons of the resin (component A) are activated with 2 fl. oz. to 26 fl. oz of accelerator. The reaction time - see metering chart - is adjusted by the quantity of accelerator used.
2. The hardener solution (component B) is produced by dissolving 1 bag (14 oz.) of hardened powder in 2 gallons of water.
3. 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.

Application Steps

NOTES ON INSTALLATION

Processing

Injection with two component pump via injection hoses or drill packer

SUBSTRATE PREPARATION

Substrate Temperature 5 °C min. / 40 °C max.

CLEANING OF TOOLS

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.
