      Not the sand part, the ocean part. Weight is usually a major factor in large scale resource industries like this, why on earth would they want wet sand? Plus thats gotta be more expensive property to buy the rights to.

        Not all sand is equal. We dredge up ocean sand because the particle shape and composition is excellent for concrete. Other sand isn’t as good.
