I have a block wall in my garage that has earth on the other side. There is a garden berm and a French drain so flooding is not an apparent problem. But when I have used the blue treated screws for concrete they rust up in a couple years.

What screws or screw/anchor would resist what ever moisture is causing this?

I had the idea that I would drill and screw as usual but maybe fill the hole with construction adhesive. Don’t know if this would make a difference but am looking for advise. I want to put up some permanent weight bearing shelves and don’t want the screws to rust and fail.

Are you usind Tapcon brand screws? Lostd of concrete screws are blue in colour but Tapcon’s are the only ones I trust.

Yes they are the blue Tapcon. I just wen to their website and apparently they make a stainless steel product. I think that just might be the way to go. I am still going to use compressed air, blow the holes out, and fill them with construction adhesive. Just for good measure.
