Repairing an exposed floor heat line

[Ric]

I have a 6" section of floor heat line near the grate in the middle of the bay which has surfaced and is exposed. The floors are 25 years old. It looks as though I am going to have to chisel out around it and tuck it back down. What can I use that will grip well and set up fast to cover it?

you can use water plug.... it comes in a powder that you mix with water much like cement. It also dries fairly quickly and even in wet conditions. You can find it at just about any hardware store....

I use Rockite, from any hardware store. Sets hard in 15-20 minutes. It is a powder, mix with water. Repairs seem to hold really well.

regular concrete will shrink slightly as it cures. Hydraulic cement on the other hand expands slightly which provides a better grip and no "crack" around the edges. It's what I use for concrete repairs, havent had any problems yet. (disclaimer: I am NOT a masonry contractor!)

(FYI, I think the "water plug" mentioned is simply a branded hyraulic cement)

I would not mess with the chiseling it out for fear of damaging. I have used a 2 part putty that I got at the swimming pool store made for patching and sealing cracks in swimming pools that you can use under water, or get the 2 part epoxy that 3M makes and patch over it.
