Composite masonry is a construction technique that combines different types of masonry units or materials to form a single structural element. This method is commonly used in modern architecture to improve the structural performance and aesthetic appeal. 

In composite masonry walls, two wythes of masonry units are constructed bonding with each other. While one wythe can be brick or stone masonry while the other can be hollow bricks. 

Some examples of composite masonry include:
Brick-backed ashlar masonry
Brick-backed stone slab facing
Rubble-backed brick masonry 

Composite masonry allows builders and engineers to leverage the unique properties of each material to enhance the overall performance of the masonry structure.

Composite Masonry topics include: Stone and brick stone composite masonry, concrete masonry, hollow clay blocks and reinforced brick masonry.
