What is a tooled control joint?

A tooled control joint refers to a masonry joint that is specifically shaped and formed using a tool in conjunction with a straight edge. This technique is used to create a neat, uniform groove in the material, allowing for controlled cracking as the masonry expands and contracts due to changes in temperature and moisture. The tooled joint not only serves a practical purpose in managing stress within the masonry but also contributes to the aesthetic quality of the structure.

This method provides the benefit of enhancing both the structural integrity and the visual appeal of masonry work. Properly tooled joints can help ensure that the building surface remains cohesive while mitigating the risk of unsightly cracks that could arise from natural settling or environmental factors.
