Electric in garage
This is done all the time both in slabs and footers, your concrete man can handle to pour and make sure the conduit remains clear they typically cover the ends with a plastic cap or duct tape. You need to have the conduit in place when they come in to set the forms, this is done by your electrician usualy as part of his rough-in. PVC is the material of choice to use, no chance of corrosion down the road. Hope that helps a bit.
All you need is ignorance and confidence and success is assured. - Mark Twain
