Back Block Sections Shadow

Criterion’s Back Block joint reinforcing system is an important safety measure to reinforce certain joints which often undergo additional stresses and are therefore more susceptible to cracking. These stresses can be caused by many reasons, including subsequent building movement or by unusual loadings such as heavy bumping of a wall, or trades people moving about in ceiling spaces. Radius Back Blocking Batten has a 2.5mm offset for blocking behind joints of plasterboard.
