What Is Masonry?
Masonry refers to construction using materials such as brick, stone, concrete, or blockwork bonded together with mortar.
Historic masonry buildings often use breathable lime mortar and softer natural stone, requiring specialist maintenance and cleaning techniques.

It is widely used for:
