Holes in concrete basement

666 Views 8 Replies 6 Participants Last post by  Missouri Bound
Hi! We are replacing our basement carpet with laminate flooring. After ripping the carpet up we discovered 4 holes and can’t seem to find what they are online. Also can these be permanently covered again?? Can anyone help? Thanks!

Have you peaked in all of the them?
The one with the blue pic looks like an electrical junction box.
Does that blue cover come off?
If they do not provide any access to anything then they surely can be covered.
BUT.....if you are not sure, draw a map with the locations so if for some strange reason you have to find them......well, you know.

It's hard to tell from the pictures, how big are they actually? Also, are they all grouped together or spread out around the room, a picture showing their location in relation to the room may be helpful.
Looks like it might be for some kind of sump pump system?
new 1 on me too & i see more basements than most
The circles are 8 inches across. Here are a couple more pictures.

Is that some kind of printing on the diamond plate cover?
Could be prep work for a radon gas extraction system....that was never used.
