Install New Joists/Blocking

What happens here

Carefully place the new joists or blocking (often pressure-treated lumber, identifiable by its green tint) into the prepared and waterproofed dadoes. Ensure they are fully seated and flush with the top of the existing joists. Use a hammer to gently tap them into place if needed, ensuring a tight fit. Once in place, secure them using appropriate fasteners (not shown but implied, e.g., structural screws or nails) to complete the structural modification.

Goal: Securely install new joists or blocking into the prepared dadoes
