Concrete : This mixture of cement, water, and sand or gravel is not just for the basement floor anymore. Color can be added to the mix, and it absorbs heat, making it ideal for a radiant heat system.
Benefits: It is as durable as tile and stone. The best choice if you want radiant heat. There is quite large number of colors and finishes.
Drawbacks: Requires a sealer to prevent staining. Heavy and requires strong support.
