We are having a concrete driveway put in next week and we want to put up a 16x16 out building next year. I am having the pad for the building done at the same time as the driveway. For safety reasons I don't want the contractor putting in the threaded anchors for the walls during the pour. How can I install these anchors next year when we are ready to put up the building?Thanks for any help.Keith

Drill holes next year and put in expanding anchors. Not an issue. Or put the anchors in now and just cover them.

Can you place anchors in a concrete slab at a later date?

in a situation like that i would think spending a few extra bucks on stainless would be worth while. some of our engineer friends here might post with some good advice,but off hand, i would look into epoxing in stainless threaded rod (provided you have access to an air compressor to clean the holes). i just don't trust espansion bolts for critical connections.

I have never seen tables on stainless verses bright steel but I know with stainless screws, they twist off twice as easy as bright steel so you might want to up the size one notch to compensate for that to make them equal to new steel.
