Why do cinder blocks crumble?

Water. Water is the primary cause for most crumbling concrete. Whether from flooding or from repeated rains, water eventually wears down the structure of a cinder block from the outside, causing it to flake off and crumble. If a block has not been properly cured, water can also infiltrate the interior of the block.

Is a cinder block wall strong?

Cinder blocks are capable of high compression strength. Here is another downside for block walls; they are more prone to water leaks because of the number of joints between each block. The cores inside the blocks can also fill with water, saturate the blocks, and create dampness inside basements.
