How high can a cinder block wall be?

It is not uncommon to create designs with an h/t from 32 to 50. That could produce wall heights of up to 33 feet for walls built with 8-inch concrete masonry units (CMU), 41 feet for 10-inch CMU, and 50 feet for 12-inch CMU. Regionally, 14- and 16-inch CMU are available, which extend possible wall heights even further.

Do cinder blocks rot?

In fact, elements from the outside, and occasionally from within, can damage, crumble and destroy cinder blocks.
