Running sch40 electrical in floor before concrete?

I always lay out my wire and then slide my conduit over it. 3/4 is too small for most things, I would go one inch.

If you want a really smooth conduit line, use one inch, white PEX. I've never used it under a slab for wire, but I use it all the time for getting wire down an exterior wall full of insulation.

Run the pair of conduit sweeps up to the box location. Either install the box and cover with tape before the pour. Bore couple of holes in scrap wood to match the box hole pattern. Slide those on the sweeps to hold the spacing during the pour.

Don't want a tee embedded in the slab. When feeding the wire though there is no way to control which port it will exit out of. Any pipe in the slab should only have one in and one out.
