geeze eh, i would think if a guy did chop it up in a couple spots you could try to carefully break away existing concrete and get to the cut and do some sort of repair on it using shark bite fittings and re pour the area.. Most systems have many loops for mainly even heating and efficiency but if you did chop up a section you couldn't repair you can just block it in. The layout for for garage design has 6 separate loops, hard to tell unless you are looking directly down on the footprint.. IN the summer i'm going to try and reverse the system and use the cool garage/basement slabs and circulate the water through at night etc. as the nights here are cool enabling this. Thats another project on the list lol.. I'm never without things to do thats for sure.
