Concrete Block Repair

What happens to masonry blocks…


There are plenty of reasons why a CMU block (concrete masonry unit), also referred to as a concrete block, wall may need to be repaired. Most of the time, these walls deteriorate due to weather. Over time, you may find that your CMU blocks are cracked if not crumbling or breaking. At CTC Masonry, we provide professional concrete block repair services to repair or replace blocks and fill cracks to prevent further damage. We provide our exceptional repair services to clients in Chicago, Illinois, and the surrounding suburbs.


Cracked CMU Block


If the mortar between concrete blocks appears to be cracked, we can easily repair the damage. Using a machine grinder in combination with a dust control vacuum, we grind out the damaged mortar to the solid bed joint and then fill it with new mortar.

Replacing a CMU Block


Sometimes concrete block repair isn’t enough. Replacing the CMU block is necessary when the block itself is chipped, deteriorated, or damaged to the point where tuck-pointing cannot fully restore the structural integrity of the wall. To replace a defective concrete block, our skilled contractors will cut out the deteriorated or spalling block and replace it with a new one that matches the existing units.
