Bridging is a common carpentry technique used to add support between floor or ceiling joists. It's like adding extra bracing or supports between the main wooden beams in a building to make the structure stronger and prevent the floor from bouncing or squeaking. There are different types of bridging: solid bridging (using small pieces of wood) and cross bridging (using X-shaped metal or wooden pieces). When carpenters mention bridging in their experience, they're talking about installing these support systems to ensure buildings are stable and meet construction codes.
