Hydrophobic concrete is concrete that repels water. It meets the standards outlined in the definition of waterproof concrete. Developed in Australia in the mid-20th century, millions of cubic yards of hydrophobic concrete have been laid in Australia, Asia, and Europe, and in the United States since 1999. Its … Meer weergeven Typical concrete is quite hydrophilic. This comes from its intricate system of tiny capillaries, which suck water through the microcrack network within a concrete slab. This hardened matrix creates a continuous "source to … Meer weergeven Hydrophobic concrete is produced in a variety of ways that fall under two categories; coatings or admixtures. Both allow the crystal structures to form in the presence of water. When creating hydrophobic concrete through a … Meer weergeven Some other cons to hydrophobic concrete come from the application process. When applied as a coating, it can only penetrate up to 12 inches into the material. Also, the coating process itself is extremely labor-intensive. If the structure is thicker than 12 inches, or it … Meer weergeven The ultimate goal when forming a hydrophobic material is to reduce the polarity of the molecules.
