Gypsum Concrete Underlayment in Portland

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

Bridge Traffic Is Your Problem. Not Ours.

Portland is our Oregon hub, and we serve it the way we serve Puget Sound — as core territory on a regular mobilization cadence, not a road trip. Because our batch plant travels on one 25-foot trailer and sets up in under 10 minutes, a Portland pour needs no local plant, no ready-mix window, and no staging yard: the rig arrives, levels itself on a curb lane or site apron, and batches to your programmed mix design with every batch weighed and archived to the cloud. GCs running work on both sides of the Columbia get one floor sub and one QC standard across the whole metro.

Building in Portland

Portland’s development pattern is corridor-driven — Division, Interstate, Foster, the Central Eastside, Slabtown — dense wood-frame podium and mid-rise product shaped by the city’s inclusionary-housing rules, alongside a deep bench of dedicated affordable projects funded by the region’s housing bonds. Affordable and bond-funded work carries real documentation obligations, and that is where a per-batch QC record earns its keep: your closeout file shows the floors went down at the specified mix, every batch, every building. The code story is the same as everywhere wood-frame: STC 50 / IIC 50 between units, 1–4 hour UL-rated assemblies, delivered by gypsum topping over acoustic mat. Portland’s wet season makes weighed water content — and the predictable dry-down that follows — a schedule tool, not a nicety.
