Laying electrical conduit in concrete slab without sealing.

[Serenity]

My contractor just ran wiring in my concrete floor to the island. He dug a shallow trench and ran the wiring through a Gray conduit. However it was not secured in with a bonding agent or concrete seal..will this be an issue..in central florida..

Your inspectors will flag it if it's a problem.

In my opinion, the concrete should be patched before the floor finish is applied.

What flooring will cover the concrete?

 

[mwm1752]

the trench with fill is the conduit securing agent & the inside of the conduit is considered a wet location so why seal it? Joints are required to be glued together.

Methinks we're not all answering the same questions.

The trench isn't required to be filled but then the conduit is required to be secured. If the tile guy fills it with thin set you're all good.

The trench should have been filled with concrete troweled flush with the existing slab. I don't see how it could be just left that way. Maybe some idiot thought that floor tiles will bridge it? Not in my book!

I'm confused. What is a 'bonding agent' or 'concrete seal'?

Exactamundo. Return the integrity of the surface, at least.

I think he means the pipe wasn’t glued together. Just pressed together.

Ten responses, nothing from the OP to date.

Electrical contractor? General contractor? General contractor having his sub electrical contractor install the conduit in the "concrete trench".

ran the wiring through a Gray conduit.

PVC conduit?

However it was not secured in with a bonding agent

Bonding agent? Meaning, supported, strapped, in place?
Bonding agent? The only bonding agent I can think that would be used is a liquid bonding agent that is brushed on the pre cleaned side walls and bottom of the concrete trench for bonding the patching cement material to the existing concrete.

or concrete seal..

As in fill the trench with a patching cement? Or?? If there is a general contractor involved he/she may be handling that.

Well, then........... that means we need to turn this into a 28-page thread, doesn't it?

Definitely, why stop now? I didnt see anything in the OP saying this was NOT a service, in which case the conduit needs to have 2" of concrete cover per 230.6(2)

I think we gave the OP enough to think about.
