Gypsum is a mineral that has been used in building materials for decades now. But when combined with concrete to form gypsum concrete, the material is still misunderstood. Despite its growth in the last 40 years, gypcrete isn’t considered to be the best option for floor underlayment. A lot of people have countless myths about gypsum concrete that keeps them away from opting this material for their new construction. In this article, we will debunk some myths associated with gypsum concrete so that you too have a clear idea.
Myth 1: Gypsum Concrete Hardly Provides any Benefits
Truth: Well, gypcrete is one of the best floor underlayment materials that provides several construction benefits. Unlike a lot of other building materials, gypsum concrete is quick and easy to install. It can offer a 2-hour fire barrier, and it slows down the speed at which a fire can engulf an entire property. The ease of working with gypcrete and its quick setting time cannot be overlooked. Plus, the end result is always a smooth finish. Along with all these benefits, gypsum concrete is also an affordable material compared to other alternatives.
Myth 2: Gypcrete Underlayment will Melt When Exposed to Water
Truth: Gypsum is soluble in water at a rate of 2 g/L of water. This means a solution rate of 2 g/L of water, 0.45 kg of gypsum would require the equivalent to about 60 gallons of water. If the floor covering had not been applied, the majority of the water would probably be absorbed by the gypsum underlayment. Even if the water is completely soaked into the gypsum underlayment, erosion will not occur because the water solution will be saturated at a rate of 2 g/1 L and will just sit in the mass.
Myth 3: Sand and Clay Make Gypcrete
Truth: The major concern with this myth is that people feel that the material is composed of sand and clay, which means that the resulting underlayment won’t be sturdy. However, it isn’t true. Concrete is a mixture of sand, gravel, and cement. Since neither clay soil nor sand contains cement, it can’t form concrete. Also, gypsum is a crystalline structure composed of calcium, sulfate and two molecules of water, which means it’s free from sand and clay. Thus, the bottom-line is that gypsum concrete provides robust and resistant underlayments for your new construction or renovation projects.
