Pit sand, also known as coarse sand or badarpur, is obtained from deep pits 1 to 2 meters below the top soil. It has rough, angular grains that are essential for binding particles together in construction. The sand is free from salts, does not absorb moisture from the air, and is generally red-orange in color due to iron oxide. Pit sand is widely used in construction due to its superior binding qualities.
