  69. 77. The Inherent Nature of Concrete Water leaving concrete as it cures leaves behind capillaries Capillaries are filled by water after the curing is complete resulting in internal stresses

  71. 79. Reasons For Waterproofing <ul><li>Leak Prevention </li></ul><ul><li>Corrosion Resistance </li></ul><ul><li>Aesthetics </li></ul>
  72. 80. How Does Krystol Work ? <ul><li>Krystol works to further react the unhydrated cement particles in concrete thereby improving the natural hydration process of concrete. </li></ul><ul><li>Krystol simultaneously fills the remaining pores and capillaries with millions of hair-like crystals resulting in impermeable concrete. </li></ul><ul><li>The Krystol reaction will penetrate throughout the concrete mass wherever moisture is present and does not shrink in the absence of moisture. </li></ul>Magnified Plain Concrete Magnified KIM Concrete

  77. 85. Below Grade Pits at Ocean Construction <ul><li>KRYSTOL T1 and KRYSTOL T2 were used to waterproof this below grade pit against significant hydrostatic water pressure in 1975. The equipment room is located at the edge of the Fraser river, 17-feet below the water table. </li></ul>“ Almost 30 years ago we used the Krystol Waterproofing Treatment to stop substantial leaking in our concrete pits. They are still dusty dry today and we have been happy customers ever since.” Ron Boyes, Superintendent, Ocean Construction Ltd .
