Sika® Watertight Concrete Powder – Combined Water-Resisting & High-Range Water-Reducing Powder Admixture
Sika® Watertight Concrete Powder is a combined water-resisting and high-range water-reducing (superplasticising) admixture used to enhance workability and reduce the water permeability of concrete. The high-range water-reducing component allows a lower water/cementitious ratio, while the water-resisting component reduces capillary absorption, producing dense, durable, watertight concrete.
Recommended Uses
- Watertight structural concrete
- Basements and foundations
- Water-retaining structures
- Roof slabs and wet areas
- Concrete requiring low permeability
