Crystalline waterproofing
Concrete, most commonly used material in building & constructions, absorbs water and often gets damaged and deteriorates. During concrete formation tiny holes and capillaries have been created that make concrete porous. Porosity in concrete makes it water permeable. Crystalline waterproofing chemicals prevents water movements in concrete by creating its own waterproofing barrier. This way chemical reduces the water permeability and porosity in conventional concrete and increases its durability and lifespan and also reduces its maintenance cost. When any liquid contacts a surface, a contact angle is formed between surface and edge of liquid drop. This contact angle should be higher to make any surface hydrophobic or very high to make it super-hydrophobic. A surface that does not have any property of hydrophobic normally has contact angle with water below 80 degrees. On the contrary, a super-hydrophobic surface creates contact angle with water at least 150 degree with water. Any surface has its surface energy while liquid has surface tension. Liquids penetrate in any surface when; surface energy > superficial tension. Low surface energy and good micro roughness make a surface hydrophobic. Leaf of lotus is considered to be a super-hydrophobic surface and repels water very well.
