Use PEX as a conduit for floor sensors in radiant heat: Take a small piece of extra PEX and slide the sensor into it. When you pour the concrete, make sure that the PEX sticks up so that that area will not be filled. This way, if you ever need to replace the sensor, you don't need to break your slab.
