Any coating on the inside of a concrete block wall will prevent the normal migration of moisture. The trapped moisture freezes inside the wall, causing mortar deterioration and spalling of the concrete blocks.
What Causes Cinder Blocks to Disintegrate?
Cinder blocks are made of concrete, and like all concrete products, they will eventually break down and disintegrate. There are several reasons why this happens, and understanding these reasons can help you extend the life of your cinder blocks.
One of the main reasons cinder blocks disintegrate is because of the freeze–thaw cycle. Water expands when it freezes, and when it does so inside the pores of concrete, it can cause the concrete to crack and break down.
This is why it‘s so important to keep cinder blocks dry, especially in cold climates. Another reason cinder blocks disintegrate is because of chemical reactions.
Concrete is made of Portland cement, which is highly alkaline. Over time, this alkalinity can cause the concrete to break down, especially if it‘s exposed to acidic substances.
This is why it‘s important to protect cinder blocks from harsh chemicals. Finally, cinder blocks can also disintegrate because of physical wear and tear.
As they‘re used and abused, the concrete can slowly break down, especially if it‘s not properly maintained. This is why it‘s so important to inspect cinder blocks regularly and repair any cracks or damage that you see.
