Gypsum underlayments are a proven solution for achieving flat, smooth, and sound-dampening floor systems in multi-family, mixed-use, and commercial construction. Applied as a lightweight pour-over topping, these underlayments provide an ideal substrate for finished flooring materials such as LVT, carpet, or hardwood. When paired with an acoustic mat or sound control membrane, gypsum underlayments also serve a critical role in reducing airborne and impact noise transmission between floors — helping builders meet or exceed STC and IIC rating requirements.
These systems are particularly effective in apartment complexes, senior living facilities, dormitories, and hotels — environments where sound attenuation and fire ratings are top priorities. Gypsum pours are also fast-curing and allow for efficient sequencing with follow-up trades, which helps keep timelines on track.
Elastizell of Wisconsin brings decades of experience to every underlayment project. Our union crews have installed millions of square feet of gypsum underlayments across Wisconsin and the Midwest. We are members of the NRDCA and operate with a full in-house team and fleet, allowing us to control quality and scheduling from start to finish. Our affiliation with LiUNA Local 113 and OPCMIA Local 599 ensures every job is executed with industry-trained labor, adhering to strict safety and performance standards.
If you’re planning a multi-story build and need a gypsum underlayment system that meets acoustic and structural specs — without compromising on turnaround — our team is ready to help.
