Basement flooring is an important element of a finished basement. When choosing the appropriate basement flooring for your basement renovating project, it is rather important that you first determine whether or not you've got a moisture barrier underneath the basement floor. If you don't have a moisture barrier underneath the concrete slab then you will have excessive moisture levels which will wick through the cement floor to the basement flooring.
To see if you do have a moisture barrier underneath your basement's floor, cut open a couple of plastic-type trash bags and place them in a few various spots on the basement floor. Spread them out on the cellar floor and tape all of them down. After a number of days get rid of the plastic trash bags from your basement floor and notice if they're wet on the bottom side. If they are, it's likely that there's no moisture barrier under the basement concrete slab. If this sounds like the way it is, your basement floor options are a lot more restricted.
It's possible, however, to increase your basement flooring choices by making use of a basement waterproofing sealant to the basement floor and to the wall surfaces. You can also have a French drain put around the basement foundation; however this is a costly endeavor as it will require excavation, gravel and PVC pipes to be put in.
If it is determined that you do have a moisture barrier underneath the basement concrete slab then there are a variety of flooring choices to decide on.
