What happens here
To enhance the structural integrity and prevent the deck's joists from bowing or twisting over time, midspan blocking is installed. This involves cutting short pieces of lumber and fitting them snugly between the main joists, typically at the midpoint of their span. Additionally, diagonal blocking is strategically placed within the framing to add rigidity and create a visually interesting sub-structure, especially where the decking will feature a pattern.
Goal: Strengthen the deck frame and prevent movement.
