The Technology to Mix Perfectly.
The Exclusive Rights to Waterproof It Permanently.
Sound Floors is Washington State’s only gypsum concrete applicator operating the SmartBatch GC1 automated batching system and the only licensed installer of the exclusive Elevation Waterproofing System. When precision matters and the warranty has to hold, there is only one contractor to call.
SmartBatch GC1
Automated Gypsum Concrete Batching SystemSound Floors is the exclusive operator of the SmartBatch GC1 in our region. While other contractors rely on manual mixing and guesswork, our automated batching technology guarantees a perfect, consistent gypsum pour on every single floor — regardless of project size, weather conditions, or crew. The GC1 monitors and controls every variable in the mix in real time. The result is a pour your structural engineer, building inspector, and flooring contractor can all rely on.
Elevation Waterproofing System
Formulated Materials — Licensed InstallerSound Floors is the only contractor in Washington State licensed to install the Elevation Waterproofing System by Formulated Materials. When architects design elevated decks and balconies in the Pacific Northwest, the Elevation System is the product they want to spec — and we are the only crew authorized to install it. Beyond the system itself, Sound Floors is the only contractor that both waterproofs the deck and pours the concrete above it. One crew. One schedule. One warranty covering the entire assembly.
