Learned Masonry as a kid from three mason teams focused on concrete, brick, and stone. I enjoy stone work. Not many masons know how to set stone, the proper cement, the correct amount of water, or take the time to sponge clean things for crisp jobs.
My father and brother are both architects having offered a lot of context and discussion over the decades of why things fail and how to repair them. I embrace repairs whole-heartedly recognizing the needs. Most everything can be repaired or covered with stone.
Concrete work is all about proper prep. That's where most masons fail - digging for gravel base. compact the gravel, proper rebar steel suspended in 4000 psi concrete with proper expansion joints.
