Drain holes are openings designed to allow water to escape from a structure or surface. They are commonly found in various applications, such as roofs, basements, and pavements, to prevent water accumulation and potential damage. By directing water away, drain holes help maintain the integrity of buildings and landscapes. These holes can vary in size and shape, depending on their purpose and location. Proper placement and maintenance of drain holes are essential to ensure effective water management. When blocked or improperly designed, they can lead to flooding, erosion, and other water-related issues.
