Exterior carpet is sometimes a better and more cost effective alternative to tile or stone flooring. It is cheaper, less maintenance, less time and easier to install, great for pets, no watering required like real grass, and gives a more cozy feeling to an exterior area. This type of flooring is commonly used on roof tops of skyscrapers to simulate grass and in dog parks for easy wash and clean up. It is also used in RV’s or in boats. This product has many other uses. How will you use it is up to you.
