The first thing most people think of when Saudi Arabia is mentioned is the desert, and therefore endless amounts of sand.
The size of Saudi Arabia is approximately 2.2 million square kilometers. A total of 95 percent of the country is desert. Of course, accordingly, there are piles and piles of sand everywhere.
However, this country regularly imports large quantities of sand.
Sand is needed for almost all major construction jobs, and even all major building materials – concrete, bricks, glass – are manufactured using sand.
In fact, this is what makes it the second most used natural commodity after water.
Considering that Saudi Arabia is undergoing major construction works, it is clear that it needs large quantities of sand.
If you thought Saudi Arabia would have no shortage of this resource and could pump truckloads of sand out of its deserts, you'd be wrong.
Saudi Arabia may be a sandy desert, but that sand is not of a quality suitable for construction. Individual desert sand granules have smooth edges that are useless for construction, while river sand has jagged edges that are needed for construction concrete.
Even ordinary beach sand is not useful as a building material due to the presence of salt in it.
Therefore, river sand is in high demand and is in short supply due to the increased level of construction activities worldwide. Furthermore, it takes hundreds of years for a river to make sand!
