PVC pipe buried directly in concrete?

Why won't he just go under the slab like everyone else?

First time I am hearing about this regarding PVC. There are expansion couplings available for movement. What kind of conduit do you prefer to use in the slab? I hope it's not aluminum.

You could install the conduit below the slab.

Never had any problems with non metallic conducts encased in concrete duct banks, even a few hundred feet between manholes. Common and done every day.

yeah and it's also against the code for the slab itself i believe.

What is the PCV going to be used for?

I have service feeds and first floor water pipes (copper) feeding through PCV in (or through) my concrete slab (my house is 22+ years old).

He didn't really say "conduit". If a conduit cracked, no real harm. If it is a water pipe, big problem. In a slab the biggest concern might be structural. You will probably end up with a crack that telegraphs the pipe's path

Hi Guys,

Thanks for your comments, and yes, I should have been more specific. The contractor wants to put a 1" water line, regular white PVC for irrigation, buried directly into the slab... there is a LOT of pipe. I told him he needs to sleeve it or wrap it, but that it can't be in direct contact with concrete. He says I am crazy. Do any of you have a code reference, or manufacturers reference, or something I can show this guy?

The answer is quite simple. You are the guy paying the bill and you don't want the pipe in the concrete. The golden rule, the guy with the gold makes the rules.

Fretwell's right; YOU are the one paying for the job and it's to meet your requirements as long as it doesn't violate code.

Now: Have you contacted your own local zoning and code enforcement offices? If not, why not? Thát is always the logical places to start with; they may have local rules for that exact thing or at least be able to give you info about it.
