Question: How To Stack Cinder Blocks Together

Can you stack cinder blocks?

Durability and moisture resistance Some moisture may eventually soak through the mortar joints. For this reason, external brickwork is generally constructed with a space separating it from the internal leaf in the form of brick veneer or cavity walling.

Why are there spaces between the concrete blocks?

To allow for the vertical mortar joints, leave a 3/8 inch gap between the blocks and lay out the block. A reference line can be created by snapping a chalk line on each side of the wall.
