We just had a home built as i was walking around the basement i noticed the relief cuts on our basement floor seemed awfully deep. I installed a vapor barrier prior to the pour so i grabbed a flashlight and an o ring pick. To my suprise the control joints are cut clean through the slab in several areas and damn near through the rest of it. Most of the cuts are 3.5+" if not all the way through the slab. I can even see my vapor barrier ripped from these cuts in several spots. My question is why. Not stop at an inch like i did years ago when i did flat work. Whats the point of my vapor barrier now? Does this cause any future issues? Thanks for the time!
