Back Blocking

Back blocking is used to reinforce unsupported butt or recessed joints and must be positioned midway between supporting members, in ceilings and walls.

Back blocking must be used in open areas of ceilings (back of recessed joints) with 3 or more joints and where there is a likelihood of excessive shrinkage and movement in the structure.
