My basement has wall-to-wall carpet in the two bedrooms and living area. The carpet was probably from the 70's when the house was built and we decided to remove it. After removing the carpet from both of the bedrooms, we noticed some water spots on the drywall and the tack strips for the carpet. It's not currently wet, but I am concerned that dampness will be an issue. We were originally going to put down an organic compound sub-laminate and then have 12" laminate put down on top of that. After noticing the water spots, I did some research and it says if there is potential for moisture, not to put down any material that might be susceptible to mold growth. This included plywood. I was thinking about putting down something like DriCore, but it contains plywood which could rot or mold (if excessive water damage occurs).
So I was hoping to find something that was waterproof. So far I've only come up with a few options, but most of them are not offered locally or for diy's:
- ThermalDry Basement Floor Matting (rigid plastic)
- ThermalDry Basement Floor Tiles (rigid plastic with tile)
- Delta Flooring (Plastic membrane)
- Superseal (Plastic dimpled Membrane)
- Tyroc (Rubber and inorganic surface board)
Does anyone have any recommendations for a breathable subflooring that is waterproof for a below grade basement? Right now I'm leaning toward using Delta Flooring because its a cheap option that I can install myself. Any other advice or experience would be helpful as well.
