What is the function of a stone or brick ledge?

The function of a stone or brick ledge primarily revolves around providing support for masonry units. When constructing a structure, the ledge serves as a horizontal projection that can bear the weight of various masonry components, such as bricks or stones stacked above it, ensuring stability and proper load distribution. This support is crucial not only for the integrity of the masonry wall but also for ensuring that the overall structure remains sound and durable over time.

In addition to this primary function, while some features might indeed contribute to aesthetics or aid in other areas like moisture drainage or maintenance, the core purpose of a ledge is fundamentally structural. It plays an essential role in the construction process, promoting longevity and resilience in masonry work.
