ever wonder why sidewalks, driveways and parking lots made of concrete have saw-cuts or grooves in them? its not to give a look of uniformity, its to control the cracking. Standard rule of thumb, saw or groove 1/3 the depth of the
concrete being poured. As for not seeing tee-boxes cracked, higher strength mix with a small pour (tee-box) and no high stress loads (no trucks, heavy equipment) on them will allow them to remain "uncracked" to the eye, but there will always be minor cracking where the most moisture gathers (underneath) when the freeze thaw cycles hit. If you live in the south, you don't have the freeze thaw cycles that we do. Sorry for the lesson, but sometimes I get OCD on myself (explains why I have 90+ discs in my personal stash!)
