Sika® Injection-306

Polyacrylic elastic injection resin for permanent watertight sealing

Sika® Injection-306 is a very low‑viscosity, elastic polyacrylic injection resin with a versatile and adjustable reaction time, suitable for use in groundwater protection zones.

  • Provides a passivating environment for embedded steel reinforcement
  • Adjustable curing time between 10 and 60 minutes
  • Permanently elastic and able to accommodate limited structural movement
  • Capable of reversibly absorbing (swelling) and releasing (shrinking) moisture
  • Very low viscosity comparable to water
  • Once cured, Sika® Injection-306 is insoluble in water and hydrocarbons and resistant to alkalis

Usage

  • Crack and joint injection
  • Injection of SikaFuko® injection hoses to seal construction joints
  • Sealing water-bearing cracks and voids
  • Sealing all types of leaking building components in damp or water saturated ground conditions  
  • Sealing leaks where there is some minor movement
  • Sealing drainage pipe joints that are, or will be, covered with damp or water saturated soil
  • Injection repair of damaged waterproofing membranes (single and double layer systems)
 

Advantages

The quantity in Table 1 of accelerator (A1) per 8,0 kg of resin (A), will yield ~20 litres of mixed resin. The total accelerator solution must always be 2000 ml (refer to example below).

*Fast reaction – additional accelerator necessary.

Example:
Ambient temperature: +15 °C (+59 °F)
Required reaction time: 30 min

Accelerator = 230 ml
Water = 1770 ml
Total volume = 2000 ml

Note:
1) When using one component pumps: Workability time (pot life) = Factor 0.8 x Reaction time (refer to metering chart)
2) The given data are laboratory parameters and may deviate depending on the situation and conditions on site.

Application steps

MIXING

The following steps must be followed in the exact order shown below

Hardener solution

Pour 10 litres of water in a clean container. Dissolve the content of 2 bags (total 80 g) of hardener powder in the water. Stir with a mixer at low speed the hardener solution thoroughly until Part B is completely dissolved.

Accelerator solution

Determine the required quantity of accelerator from the accelerator metering chart (Table 1). Dilute the selected quantity of accelerator with water to a total quantity of 2 litres accelerator solution.

Accelerator solution with Part A resin

Pour the 2 litres of accelerator solution into 1 x 8.0 kg container of Part A and shake/mix thoroughly.

Resin solution with hardener solution

Depending on the type of injection pump used activate the injection resin using one of the methods below:

  • One component pump: Pour a partial amount of the final pre-mixed solution in the ratio of 1:1 by volume into a clean mixing container. Mix thoroughly and pour into the storage container of the pump.

  • Two component pump: Pour the resin solution into the storage container of the pumps ‘A’ side. Pour the Hardener Solution into the storage container of the pumps ‘B’ side. Then pump at a ratio of 1:1 by volume.

 

CLEANING OF EQUIPMENT
