Gypsum Cement Underlayment

Use this 3 part SimpleSpecs specification template to specify poured-in-place, self-leveling gypsum cement underlayment.

Overview of Gypsum Cement

Self-Leveling Properties: Are self-leveling, making them an ideal solution for creating smooth and level surfaces. This characteristic is crucial in commercial projects where precision and a high-quality finish are paramount. The ability to self-level reduces labor costs and time spent on floor preparation, directly impacting project timelines and budgets.

Compatibility with Structural Floors: Are designed to be applied over concrete or plywood structural floors. While they don’t provide structural support themselves, they play a vital role in preparing the floor for final finishes. Their compatibility with different substrates makes them versatile for various commercial applications, from office buildings to retail spaces.

Suitability for Interior Use: Specifically formulated for interior applications, gypsum cement underlayments ensure that commercial spaces meet aesthetic and functional standards. However, they are not suitable for exterior use and must be covered with finished flooring materials to protect them from wear and environmental conditions.

Enhanced Floor Systems: Integrating gypsum underlayments with radiant floor heating systems can improve a building’s energy efficiency and comfort. Additionally, using gypsum underlayments with sound mats or boards enhances STC (Sound Transmission Class) and IIC (Impact Insulation Class) ratings, crucial in commercial settings where noise reduction is essential.

Lightweight yet Strong: Gypsum concrete’s lightweight nature offers significant advantages, such as reduced structural load and easier handling and transportation. A 1.5-inch slab of gypsum concrete is lighter than traditional concrete, yet it delivers comparable compressive strength, making it suitable for use as both underlayment and top coat flooring in commercial projects.

Fire Resistance: Inherent fire-resistant properties add an essential safety layer to commercial projects. UL-listed assemblies further assure compliance with stringent fire safety standards, making gypsum cement underlayments a preferred choice in commercial construction.
