Sika® Injection-306

Elastic polyacrylic injection resin used for permanent watertight sealing

Sika® Injection-306 is a very low viscous, elastic polyacrylic injection resin with a versatile and adjustable reaction time.

  • Adjustable curing time between 8 and 50 minutes
  • Permanently elastic, can absorb limited movements
  • Capable of reversibly absorbing (swelling) and releasing (shrinking) moisture
  • Solvent free acrylic resin
  • High pH-value of 9 to 10
  • Very low viscosity comparable to that of water
  • Cured Sika® Injection-306 is insoluble in water and hydrocarbons and resistant to acids and alkalis
  • Can be used in ground water protection zones

Usage

  • Sika® Injection-306 is used for the repair by injection of damaged waterproofing membranes (single and double layer system).
  • Sika® Injection-306 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.
  • Sika® Injection-306 is used for the injection of SikaFuko® injection hoses to seal construction joints.
  • Sika® Injection-306 can be used to seal water-bearing cracks and voids.
  • Sika® Injection-306 can be used for making new sealing walls (curtains) in damp or water saturated ground conditions, situated in close proximity to the building component or within the building structure.

  1. Quantity of Accelerator per 8 kg component A to, yield of 20 liters kg mixed resin (the Total Accelerator solution must be 2000 ml 2 liters – see example below).
  2. Fast reaction – additional accelerator necessary.

Example:
Ambient temperature: 10 °C (50 °F)
Required reaction time: 25 min

Accelerator in ml = 480 ml
Water in ml = 1520 ml
Total volume = 2000 ml

Application steps

MIXING

  1. Dissolve the content of 2 bags of the hardener powder in 10 litres of water in a separate, clean container. Stir the hardener solution thoroughly until the hardener powder is completely dissolved.
  2. Determine the required quantity of accelerator from the Accelerator Metering Chart (Mixing Ratio), considering the ambient processing temperature and the required reaction time. Dilute the selected quantity of accelerator with water to a total quantity of 2 litres in a separate, clean container.
  3. Pour the 2 litres of accelerator solution into a 8 kg canister of component A (Resin) and mix thoroughly by shaking the canister.

The injection resin is activated depending on the type of injection pump used:

  • When using a one-component pump: Pour partial amount of the premixed components in a ratio of 1:1 by volume into a clean mixing container and mix mechanically.
  • When using a two-component pump: Fill partial amounts of the premixed components into the storage container of the pump. Set the pump to work at amixing ratio of 1:1 by volume.
