Polyurethane flexible injection resin for temporary waterstopping 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-AC10 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-AC10 in cold temperatures (< + 10 °C)

* Dosage of Sika® Injection-AC10 in % by weight of Sika® Injection-101 RC (Parts A+B) 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 +5 °C min. / +35 °C max.
