I would like to add a under slab circuit in my living room. I have tile over concrete and the nearest wall is 5 ft away. I want to pull #12 from a wall outlet under the slab to the center of the room for a floor receptacle. What would be the best method of pulling the wire without digging up the floor?

The only method is directional boring, and this is way too much for such a small run. This is the only trick to not digging.

A 100 foot run cost me $36,000.00, do the math.

Now if you can get to drive a large conduit under the floor from the outer perimeter, and drill a large hole at the outlet location, and can have the two meet, you just may get this done.
