Hello,
I jave just put up a garage and installed radiant heat tubing in the concrete. It has 2" of blue board and is 6" thick. the problem is I didnt remove all the water in the tubes after i poured and due to cold weather the tubes decided to rupture. What do I do now? I still want radiant heat in the concrete. Can I pour a thin layer of concrete over the first with more tubing? If so how thin can i go? I do steel fabrication so i worry about hurting the pipes due to stresses and shock on the floor surface. I dont want to pour too much due to the high cost of concrete. Then againe, I dont want to do this too many more times one screw-up is enough. If I do pour another layer how do I bond them, mechanicly, with some type of adhesive or just let the concrete do its thing?

first, why was there water in the tubing before you were ready to start the system? sorry, i dont mean rub it in but your message says you didnt get the water out after you poured the concrete, are you saying you had wter in the tubing before you poured the concrete????? if so why

if you can locate breaks though the concrete via wet spots then you could chisel out concrete and fix the pipe. although i would suspect multple breaks.

as long as head room isnt an issue you could pour another pad with more tubing, i dont think bonding is the promblem but with a two inch pad cracking may be an issue.
good luck

I had water in the tubing because the person I purchased the tubing from said to do so. He said this was to find any leaks and to prevent the tubes from kinking. The slab is 6" with 2" of insulation (blue board) under. What is the min. thickness you would pour with 5/8" tubing?

check each loop first. the car doesnt car if it is 50 in the garage. and 50 is a a working mans environment for sure. who knows maybe you have enough tubing in the slab already on one loop and it can do its thing with out the other loop. if both loops ruptured. where? is the next biggie. comming out of the floor? fix it. in the floor?
find it cut and couple it wrap it in a bit of insulation or sill sealer mix up some speed crete with acrylic strike it flat and go on with life. every where and any where? pull the doors off redoo the headers pour 1 1/2" over it use 1/2" wirsbo with 3/4"minus and acrylic strike it flat or not. put a modine heater off the boiler in the garage and bag all the extra work.
