A Dimple Sheet is a unique type of metal or plastic sheet that features evenly spaced, raised dimples created during the manufacturing process. These dimples serve a practical purpose by forming an air or drainage gap, which makes the sheet perfect for applications like waterproofing, thermal insulation, and drainage. It's commonly found in construction, particularly in foundation walls and green roofs, where it plays a crucial role in protecting structures from moisture and boosting their durability.
