Concrete block, also known as a cinder block, or concrete masonry unit (CMU) can be found in most homes built between the mid-1940's and the mid-1980's. Block is typically installed using layers (or courses) and staggering or offsetting the blocks. Concrete blocks are normally produced with hollow centers (cores) to reduce weight, improve insulation, and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built.
Concrete blocks are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them.
Concrete blocks also have a useful lifespan. This lifespan is directly effected by water and pressure. What happens over time is water will find its way into the blocks after the freezing and thawing cycle pushes your wall and creates small cracks in the mortar. This water sits in your hollow block and degrades the blocks strength from the inside. In time, you will start to see efflorescence (white power), mold, mildew. This eventually leads to block degrading to the point of failure.
