What is the importance of the base course in masonry construction?

It is decorative and enhances appearance

It holds moisture to aid curing

It provides a stable foundation for the wall

The base course in masonry construction is critical because it provides a stable foundation for the wall. A solid base course ensures that the weight of the wall is evenly distributed and minimizes the risk of settling or shifting over time. Properly laid base courses help to prevent structural issues, such as cracking or bowing, that can arise from an unstable foundation. This foundational layer is often wider and designed to support the subsequent layers of masonry above it.

While elements of decoration and moisture retention can play roles in masonry, the primary function of the base course is to create a reliable and secure start for the wall construction, ensuring its longevity and stability.
