Gypsum Concrete Underlayment in Seattle

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

Built for Tight Seattle Sites

Seattle multifamily is built on tight lots, often a 5-over-1 with one curb lane for staging. The Smart Batch® GC-1 was made for that: a single 25-foot trailer that sets up in under 10 minutes, batches from enclosed supersacks with roughly 94% less airborne dust than bag-breaking (per Smart Batch Systems), and pumps to upper floors from one parking strip.

Building in Seattle

Seattle’s upzones keep the pipeline full of podium and mid-rise wood frame, where every floor needs its UL-rated assembly and STC 50 / IIC 50 between units. Our per-batch cloud QC reports give your closeout file a document trail most subs cannot produce, and up to 40,000 sq ft/day keeps floors off the critical path.
