Crystalline Waterproofing Powder Concrete Admixture - CRYSTAL PW 25

Description

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.
• Garage.

Features and Benefits

• Protects the concrete against negative and positive water pressure (14 bars).
• Resistant to extreme hydrostatic pressure.
• Highly resistant to corrosive chemicals.
• 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.
• Protects against water, chloride, and sulfate ingress; increases resistance to chemical attacks
• 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.
• It becomes an integral part of the concrete and improves the durability of the concrete.
• 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.

Application Procedure

Application Method

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.

Consumption

CRYSTAL PW 25 is added 0,7-2,0 % by weight of cement on the mixture.
