🧱 Joldagi Brick – Description
Joldagi Brick (also spelled "Jol Dagi Brick" or "জলদাগী ইট" in Bengali) is a low-quality, under-burnt brick commonly found in parts of Bangladesh and Eastern India. The name “Joldagi” literally translates to “water-soaked” or “moist”, referring to its softness, high water absorption, and incomplete burning during manufacturing.
❌ Joldagi Brick is NOT suitable for structural construction. It is considered one of the lowest grades of bricks.
