Does breezeblocks absorb water

Breezeblocks, also known as concrete masonry units (CMUs), can absorb some water due to their porous nature. However, the extent of water absorption depends on the specific type of breezeblock and its manufacturing properties. To reduce water absorption, breezeblocks can be treated with sealants or coatings. In general, while they can absorb moisture, they are not as absorbent as other materials like wood or certain types of brick.
