The importance of proper drainage

Q. What is the importance of proper drainage in concrete structures?


A. Inadequate drainage permits ponding, and harmful solutions, such as those from deicing salts, that are ponded on concrete might penetrate into concrete and cause deterioration. With proper drainage, these harmful solutions are kept from easily penetrating into concrete.
