The wall that collapsed consisted of 93 cinder blocks that were hollow and non-bearing, and the top of the wall had no covering on the top of the wall.

Solid blocks are heavier than hollow concrete blocks, making them difficult to transport and handle. The strength of the hollow concrete block is useful for good load-bearing capabilities.
