The regulation regarding the depth of chases and recesses in masonry walls is important for maintaining the structural integrity and load-bearing capacity of the wall. The guideline specifies that they should not be deeper than one third of the wall thickness. This limit is established to prevent weakening of the wall, which could lead to potential structural failures. When chases or recesses are cut too deep, it compromises the wall's ability to bear loads and can create vulnerabilities that may affect the wall's overall performance, particularly in terms of stability and resistance to cracking.

In contrast to this standard, depths greater than one third might result in insufficient material remaining to support structural elements, thereby increasing risks during both the construction phase and while the building is in use. Therefore, adhering to this guideline helps ensure that masonry walls remain strong and secure.
