Durability is the most important thing to consider in material for coastal construction.
Therefore, the sand, aggregate and water used for making mortar and concrete needs to be free from harmful salts, chlorides, sulphates, as they can adversely impact the strength and durability of the construction.
Also, it is recommended to consult a structural engineer to design the structure and adhere to the recommended grades of concrete for the structure.
