Crystalline Waterproofing Powder Concrete Admixture - CRYSTAL PW 25
CRYSTAL PW 25
CRYSTAL PW 25 is a waterproofing concrete admixture that reacts with moisture into the concrete and forms crystal fiber on the pores and capillary gaps of concrete to provide permanently water impermeability.
Fields of Application
- Foundations, basements,
- Tunnels, dams,
- Precast concrete elements,
- Potable water tanks and waste water tanks,
- Water treatment plant,
- Swimming pools,
- Elevator pits,
Features and Benefits
- Protects the concrete against negative and positive water pressure.
- Resistant to extreme hydrostatic pressure.
- Provides permanently active waterproofing. During the curing time, it creates insoluble nano structural crystal into the capillary cracks.
- Non toxic. Safely used in water tanks.
- Water vapor permeable. It allows the building to breath.
- Easy to prepare and apply.
- Suitable for bored piled raft insulation.
- Cover the cracks up to 0.4 mm.
- Provides long term protection even though concrete surface is damaged.
- Does not need to any additional waterproofing applications.
- Does not harm for human health and environment.
Water/Cement ratio should be ≤ 0,55. CRYSTAL PW 25 is mixed with water as the ratio of 1:0,4 and then added into the mixture and mixed well minimum 5 minutes. After mixing, mixtured concrete is poured.
CRYSTAL PW 25 is added 0,7-2 % by weight of cement on the mixture.
