I am sorry but whoever said emt in not an outdoor product is wrong. As long as you use the proper raintight fittings EMT can be piped outside. i have done it in 30 different cities and no one has ever had a problem with it. the job should have been done in at least EMT. They also make fittings for EMT that are concrete tight, so you can use it in a slab if you wanted to. i would not recommend it but it is possible. The sealtite done by the electricans looks terrible.
