What is a 'base course' in masonry?

The last row of bricks finished
The bottom row of bricks that is set upon the foundation
The connecting layer between bricks and mortar
A decorative layer at the top of the wall

The correct answer is: The bottom row of bricks that is set upon the foundation

The term 'base course' in masonry refers to the bottom row of bricks that are set directly upon the foundation. This course is critical as it provides a strong, stable foundation for the entire wall structure that is built above it. The base course ensures that the weight of the masonry is distributed properly and helps prevent moisture from entering the wall. Additionally, the materials used for the base course often need to be durable and resistant to environmental conditions, as this layer must withstand the forces and elements that come into contact with the base of the wall. The installation of the base course is typically executed with careful attention to level and alignment, playing a foundational role in the integrity of the masonry work that follows.
