Blockwork ‘T’ Junction CORE

As with returns in blockwork the minimum overlap on ‘T’ junctions should be a quarter of a block. This is achieved by building the 100mm piece on alternate courses. The amount of cutting will be determined by the position of the indent in relation to the blocks in the main wall.

Junction position off centre reduces the amount of cutting to be done.

The off cut from course 1 can be used in course 2.
