Unhappy Basement floor is lumpy.

The basement floor is cement covered with carpet, and I have noticed that there are lumps starting to appear on the floor. It has not been an extra wet month, so I know that water can't be the problem. Has anyone out there ever had a problem like this before I rip up the carpet.

I've seen carpets do that and there wasn't a water problem. Is it a 'glue down' or is there tackless around the edges?

I never understood why it's called tackless when it's full of tacks.

Unhappy Lumpy Cement

The home is over 30 years old. The carpet is just a rubber backed carpet but glued down. It is not the carpet that is lumped but the cement underneath it. It almost feels like tree roots but there are no large trees around this side of the house. I really don't want to slice the carpet to inspect it but guess that will be plan B. Thank you for your reply.

Lumpy Cement

They vary in size, some small and the largest around 4 inches X 2 inches. They just seem to appear at random.

It sounds like the glue is losing it's stickem for lack of a better word. I think you are going to have to remove the carpet and start again.
