Gypsum Concrete Underlayment in Washington

Computer-batched pours, documented QC, and code-ready sound control for multifamily builders in Washington.

The Home-State Advantage

Sound Floors and our Smart Batch® GC-1 batch plant are based in Puyallup, putting the Puget Sound corridor within a morning mobilization and Vancouver and Spokane within a planned pour window. We are Washington’s Smart Batch®-equipped gypsum concrete crew: every batch weighed by computer and reported for your closeout file.

Growth, Density, and Sound Ratings

Washington’s growth strategy keeps pushing housing into wood-frame multifamily: garden-style along I-5 and I-405, 5-over-1 podium in the urban centers, and townhome infill wherever zoning allows. Each needs a UL fire-rated assembly meeting the IBC’s STC 50 / IIC 50 between units: in wood frame, gypsum concrete over an acoustic mat. In our wet season, computer-controlled water content keeps dry times predictable.
