Depth of tubing in the slab
S Milne
Member Posts: 112
I am doing a job that wil have a garage poured slab with tubing.
The contractor would like the tubing put down on the foam board and then the wire mesh. He's afraid of putting something thru it while achoring the cabnits and such.
I remember a conversation here about the performance of tubing that is lower in the slab. Anyone have some lit. that I can pass on to him ?

Generally you want 2" of concrete over the tube. This should allow plenty of room for a 1" long anchor. Plenty to hold cabinets, etc.
About the only way to keep the tubing at an exact depth would be to use continous strip rebar chairs. 1-1?2 tall cahais work well in a 4" pour. Gets a little pricey with mesh, however, as you need them every couple feet to support thin wire mesh. Great for rebar though.
Given the lesser of two evils I feel best leaving the tube at the bottom of a 3-1/2 - 4" pour. Keeps it out of harms way for control cuts and anchors. Worth a little response time IMO.
