What are types of rubble masonary?

Rubble masonry is primarily categorized into two types: random rubble and dressed rubble. Random rubble consists of irregularly shaped stones laid without a specific pattern, often used for its natural appearance and strength. Dressed rubble, on the other hand, involves stones that have been cut and shaped to fit together more neatly, providing a more uniform look and often used in more refined structures. Both types are valued for their durability and aesthetic appeal in construction.
