Does my concrete wall behind the tile look okay to you?

Just got these tiles off and I don't know what I'm looking at. Just wanted to make sure the wall is in okay shape in your opinion. If it is, can I go ahead and re-tile this area? Thanks for any advice :-)

    @SC'83 This doesn't look right to me, but maybe someone who works with concrete like @Ponce Construction would have a better idea.

    It almost looks that at one time holes were drilled for electric cords but I would have it looked at by someone who knows cement. Also check behind the other tiles.

    It looks fine. Put sanded grout into the holes and let cure before you re-tile. The surface will get floated in when you re-tile but watch the face of the new tile to keep them in the same plane as the old with a big rubber float (the notches on your trowel won't keep them even with an uneven bed surface). The concrete surface doesn't appear to be crumbly - as long as it is hard and sound you will be fine to go over. : ) Good luck with your project!

    Was there a lavatory mounted here?
