What is a lip engaging buttress?

A lip engaging buttress is a structural feature in architecture or engineering that enhances stability by connecting the main body of a structure to its foundation or surrounding elements. This type of buttress typically extends outward and is designed to distribute loads more evenly, preventing structural failure. It often features a lip or overhang that helps channel water away from the structure, thereby reducing erosion and moisture-related damage. Overall, it serves both aesthetic and functional purposes in building design.
