Sandstone is permeable. Gases and liquids can easily pass through because of this. Sand-sized silicate granules make up sandstone. Sandstone makes up 20–25% of the composition of all sedimentary rocks. Most of those rocks are porous enough to store much water while allowing water to pass through them and filter it. Sandstone is perfect for building pipes since it can pass through oil and gas. Sandstone also makes TV screens, computer chips, fiberglass, construction stones, and surface liners.
