As the world’s cities experience rapid growth, the global construction industry has been expanding exponentially. As a result, the demand for and price of river sand, which is the favoured natural material to produce mortar and concrete, has also increased.

GWP Sri Lanka and its partners successfully contributed to a better regulated river sand mining sector.
