river sand

Waterway floor granules

River sand is sand found in or collected from riverbeds, characterized by smooth, rounded grains worn down by water flow.

It's valued in construction for concrete and mortar because its texture bonds well with cement.

The contractor specified river sand for the foundation mix.

Distinguished from sharper pit sand or finer beach sand.
