    Krystol Internal Membrane (KIM) waterproofing admixture for concrete

    Krystol Group Pty Ltd

    Krystol Internal Membrane (KIM) is a chemical admixture in dry powdered form used to create waterproof concrete.
     
    Available from Krystol Group Pty Ltd , KIM is combined with fresh concrete, and used in place of externally applied surface membranes to protect against moisture transmission, chemical attack and corrosion of reinforcing steel.
     
    Mixed with fresh concrete, the unique and proven Krystol technology reacts with un-hydrated cement particles to form millions of needle-like crystals. Over a period of weeks and months, these crystals grow, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants.
     
    The KIM waterproofing admixture for concrete delivers ongoing benefits by ensuring that the crystallisation process is again triggered by incoming water from fresh cracks formed due to settling or shrinkage, creating additional crystals that fill the cracks and ensure that the structure’s waterproofing barrier is maintained and protected.
     
    KIM concrete admixture additionally enhances the natural hydration process by intensifying and prolonging the hydration of the cementing materials, which reduces the size and number of capillary pores within the concrete matrix, making it dramatically less porous, and improving strength and durability characteristics.
     
    Key features of KIM chemical admixture:
     
    • Replaces unreliable exterior membranes, liners and coatings
    • Easily added directly to ready-mix truck or at batch plant
    • Self-seals hairline cracks up to 0.5mm
    • Reactivates in the presence of moisture
    • Effective against hydrostatic pressure up to 140m of head pressure
    • Waterproofs from any direction
    • Impervious to physical damage and deterioration
    • Safe for contact with potable water
    • Reduces concrete shrinkage and cracking
    • Provides excellent resistance to waterborne chemicals such as sulphates, chlorides, and acids
    • Compatible with self-compacting concrete (SCC)
    Key benefits of KIM concrete admixture:
     
    • Permanently waterproofs concrete
    • Increases reliability and quality control
    • Lowers the cost of waterproofing by up to 40%
    • Cuts weeks off the construction schedule
    • Reduces the cost of maintenance and repairs
    • Increases revenues with a larger building footprint
