When considering basement flooring options, most people only consider the typical products: carpet, tile, vinyl, wood or floor paint. Don't be lead into the traditional methods - many times they're doomed for failure. Basement floors are prone to (the exciting and fun) water damage that can occur during a heavy rain.
Even if it is something that happens just once every 10 - 20 years, it
is a nightmare having to remove
damp and moldy carpet and carpet padding (just see how well that
linoleum stays nice and flat after soaking in some water for just
a little bit!).
After proper hydrostatic testing (checking for any water problems) on the basement floor, you'll know whether or not if your floor is a good candidate for one of the many decorative concrete options available. Even with moisture problems, there is a solution solve it (any coating can be placed over this "moisture vapor barrier".
A common decorative concrete option for your basement is a vinyl chip epoxy application as shown in the two close-up pictures below.
With just a slight change in the chip color blend, you can really change the look (which may not be as noticable in these close-up shots - but if you would be looking across the complete floor, the overall look of one would look like a completely different color than the other. If you gave the floor another layer of epoxy, you would extremely change texture of the floor surface.
Notice the difference of the close-up pictures above and below of a vinyl epoxy chip floor (with 100% coverage).
The picture above and below are the exact same five color combination except the main color in the chips is at a 62% blend of a tan color in the above picture and it is at a 62% blend of a gray color in the one below. Also, the picture on top has only one layer of a clear 100% solids epoxy on it and the one below has two layers of a clear 100% solids epoxy on it.
