Continuing the cellar work, I've read some conflicting info about using 18mm ply to sister/scab damaged joists. Half the internet seems to be a fan, the rest say stick to 2' timber.
Would anyone like to weigh in before I flip a coin and head to the timber yard? Is ply actually stronger on edge or is that an "it depends" kind of question?
