Sika® UCS Pak
Underwater / Anti-washout admixture
Sika® UCS Pak is a powdered underwater/anti-washout admixture formulated to increase the cohesion of concrete, enabling significant reductions in both binder washout in underwater concrete and static segregation for piled concrete in absorbent ground.
Sika® UCS Pak has the following characteristics and should be used in combination with a Sika® HRWR/Superplasticiser:
- Strong increase in cohesion
- Extended workability
- Superior anti-washout properties
- Provides improved integrity of concrete placed underwater
- Reduced segregation and moisture loss to ground in concrete piles
- Less segregation and bleed
- Packaged in water soluble bags for easy dispensing
