It weighs under normal concrete even though preserving equivalent compressive strength and charges. Additionally it is straightforward to work with and stage, making it possible for for more quickly installation and better productivity. Using gypsum concrete for radiant warmth flooring became well known during the 1980s with the introduction of plastic PEX tubing, which is not susceptible to corrosion with the concrete.
