Sika® Injection-101 RC
Sika® Injection-101 RC is a 2-part, polyurethane, low viscous, fast foaming, water-reactive injection resin. It cures to a dense flexible foam.
- Foaming reaction only takes place in direct contact with water
- Can be injected as a single component system
- Free foaming expansion up to 40 times
- Can be accelerated using Sika® Injection AC-10 in cold temperatures (< +10 °C)
Usage
- Temporary waterstopping of high water intrusions in cracks, joints and cavities in concrete and masonry.
- Waterstopping in special applications such as bored or sheet pile walls, anchor heads and microtunneling.
- To achieve permanent watertight crack sealing inject with Sika® Injection-201 CE or Sika® Injection-203 after temporary waterstopping.
Advantages
- Foaming reaction only takes place in direct contact with water
- Can be injected as a single component system
- Free foaming expansion up to 40 times
- Can be accelerated using Sika® Injection AC-10 in cold temperatures (< +10 °C)

The data above are laboratory parameters and may deviate depending on the situation and conditions on site.
The reaction speed (foam formation) is influenced by the temperatures of the mixed material, the structure and the contact water, plus the hydrodynamic conditions.
Smaller volumes can be used at a ratio of Part A : Part B = 1:1 by volume
Ambient Air Temperature
+5 °C min. / +35 °C max.
Substrate Temperature

Pot Life
| ~2 hours (at + 20 °C) | (ISO 9514) |
MIXING
Empty Parts A + B into a mixing vessel and mix slowly and thoroughly for at least 3 min (max. 250 rpm) until completely mixed.
After mixing, pour the material into the pump’s feed container, stir briefly and use within the pot life.
If the substrate and/or ambient temperatures are < +10 °C, Sika® Injection AC-10 can be added to Sika® Injection-101 RC to accelerate the start of expansion.

FAQ
1-component or 2-components PU injection foam/resin can be used to seal leakages on cracked concrete.

For more information, please consult Sika’s Technical Service Department.
PU injection foam requires water to react. As it reacts, it will foam and expand to stop the water leaks within a short period. PU Injection foam are normally injected into cracks that are constantly wet with flowing water.
PU injection resin do not foam when in direct contact with water (non-reactive to water). It is usedfor permanent water-tight sealing with some flexibility to absorb limited movement, in dry or damp cracks and joints. It is not suitable to be injected into cracks that are constantly wet with flowing water.
