Those resources are also exhausting very rapidly. So it is a need of the time to find some substitute to natural river sand. The artificial sand produced by proper machines can be a better substitute to river sand. The sand must be of proper gradation (it should have particles from 150 microns to 4.75 mm in proper proportion).

Beach sand is moved from the low-tide beach to the upper back beach (independent of building artificial dunes) as an erosion-mitigation technique. In effect this is beach erosion! A relatively thin layer of sand (≤30 cm) is removed from over the entire lower beach using a variety of heavy machinery (drag, grader, bulldozer, front-end loader

Natural Zeolite. Porous zeolites form when ash and volcanic rocks react with groundwater. This infill neutralizes pet odors but, its lightweight makes it inappropriate as a primary infill. Instead, it is advisable to use a heavier sand or rubber infill on the base and top it with a secondary layer of zeolite infill.
