We installed good laminate flooring with foam backing on our basement cement floor. It continues to lift in spots even though it is glued in spots but it is interlocking.

How can we stop it from lifting in spots? Our socks catch on spots and the cats claws are as well.

The floor was swept well and the cement was in good repair and the laminate was top of the line with foam backing already attached. Interlocking. Certain pieces just keep lifting and some have been glued.

What can we do to keep it laying flat being as it is interlocking flooring?

I think you may have water vapour pushing up through the concrete.

A simple test to determine if moisture is coming up is to lay a piece of 6 mil plastic 12"x12" on the floor and tape all sides down and leave it for 24 hours or longer. If moisture is seen under the plastic you have water vapour coming up from the floor.

In my opinion laminate should not be installed directly on basement floors and the plastic test should have been conducted first before purchasing and installing the floor.
