tection zones.
USES
Sika® Injection-306 may only be used by experienced
professionals.
▪ Crack and joint injection
▪ Injection of SikaFuko® injection hoses to seal con-
struction 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 mem-
branes (single and double layer systems)
CHARACTERISTICS / ADVANTAGES
▪ Provides a passivating environment for embedded
steel reinforcement
▪ Adjustable curing time between 10 and 60 minutes
▪ Permanently elastic, can absorb limited movement
▪ Capable of reversibly absorbing (swelling) and releas-
ing (shrinking) moisture
▪ Very low viscosity comparable to water
▪ Cured Sika® Injection-306 is insoluble in water and
hydrocarbons and resistant to alkalis

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.
