How do stitch drills affect the concrete when applying a breaker?

Stitch drills, when used with breakers on concrete, create holes that allow for a more controlled and effective application of force. These holes enable the concrete to be placed in shear or tension effectively, facilitating the breaking process. This technique emphasizes the importance of understanding how different drilling patterns interact with the concrete structure. By allowing for controlled application, stitch drills help in managing the distribution of stresses within the material, thereby optimizing the breaking efficiency of the breaker.

Other answers reflect different effects that are not pertinent to the mechanical interaction created by stitch drills. While options discussing aesthetic finish or moisture absorption may seem relevant in construction, they do not directly relate to the mechanics of how stitch drills interact with concrete during the application of a breaker.
