Pouring Concrete over Conduit

I'm construting a side walk adjacent to my garage. There's two tv and internet cables (not together) in conduit that will be covered in the concrete pour. Should I put any materials over the conduit so the concrete doesn't cover the conduit directly? Comments!

You generally want to fill and screed your forms with a little sand or gravel, which gets tamped down prior to pouring concrete. This provides drainage as well as consistent depth for the concrete. The main reason you don't want the conduit embedded in concrete is so that it isn't destroyed someday if the concrete needs to get torn out and replaced.

In other words, go below the concrete! Always a good idea to place an extra conduit or PVC pipe or two under the walk you never know what and when you will want to pull something under that slab and you will be so glad you did that!

Rebar

I plan to use rebar. So should I spread some general purpose gravel over the conduit? Would this act as a layer between the conduit and concrete?

Yes. Gravel = sand or gravel.
