A "mortise" refers to a cavity or hole that is cut into a piece of material, typically wood, to receive a corresponding projection known as a tenon. This joint is commonly used in woodworking and carpentry to connect two pieces of wood at an angle, usually at 90 degrees, forming a strong and stable connection. The mortise-and-tenon joint is a traditional and widely used method for joining structural elements, such as beams and posts, in construction. It is valued for its strength and durability, making it a preferred choice in various construction applications, including framing, cabinetry, and furniture making.

Key Characteristics of Mortise in Australian Commercial Construction Projects

• A hole or recess cut into a piece of wood or other building material
• Designed to receive a corresponding projection (tenon) to form a strong and stable joint
• Provides maximum side-to-side grain surface area for a robust and durable connection
• Commonly used in construction projects, including commercial buildings and furniture making
• Particularly useful in locations with high foot traffic and potential for wear and tear
