Concrete waterproofing and durability enhancing admixture.
Suitable for providing permanent protection for all concrete that will be subject to water pressure, such as:
KIM is an effective waterproofing system for rigid concrete structures only and may not reliably seal cracks and joints that experience variable loading or repeated movement.
A hydrophilic crystalline admixture used to create permanently waterproof concrete. The product lowers the permeability of concrete and is used in place of surface applied waterproofing membranes. By stopping the transmission of water through concrete, the product adds durability and longevity to concrete by protecting it against chemical attack and corrosion of reinforcing steel.
When added to concrete, Krystol chemically reacts with water and un-hydrated cement particles to form insoluble needle-shaped crystals that fill capillary pores and micro-cracks in the concrete and block the pathways for water and waterborne contaminants. Any moisture introduced over the lifespan of the concrete will initiate crystallization, ensuring permanent waterproofing protection.
Features and benefits:
Consult technical literature for details on workability, permeability, corrosion resistance, sulphate resistance, self-sealing performance, chloride ion content and shrinkage and crack reduction.
