When it comes to choosing a floor type for your basement, your options are somewhat limited.
Less permeable stone floor types such as flagstones, granite and slate can make for a perfect basement floor. Slate tiles, stone tiles and ceramic tiles can all be installed below grade, but like concrete, also need to be sealed.
If you want a basement floor that can withstand a below grade environment and is also eco-friendly, look no further than ceramic tiles. When properly sealed, ceramic tile floors can hold up well to moisture exposure. They can also be made with up to 70% recycled materials such as windshield and used glass bottles. In addition to being as strong or stronger as tiles made with newer materials, green ceramic tiles are often cheaper.
