Acid-Resistant Brewery Concrete Floors in Portland
Fermentation tanks, caustic washdown cycles, and acidic spills demand a concrete floor built for chemical attack. Portland Concrete installs urethane and epoxy systems rated for brewery and winery production, with trench drains sloped to move washdown water fast. Tasting rooms and bar areas get a separate, showroom-quality finish. Free written estimate on every project.
Wort is acidic. Cleaning chemicals are caustic. Wine brings tannic acid. Washdown cycles run hot. A typical commercial epoxy floor breaks down under this combination within months because it was never designed for the chemical load. Brewery concrete needs a urethane cement system (4-6mm hand-troweled) or a specialized chemical-resistant epoxy rated for fermentation environments.
The second critical piece is drainage. Brewery washdown produces gallons per minute. Point drains cannot handle that volume, water pools on the slab, and chemical exposure extends. Trench drains across the production zone capture and move water in seconds, keeping the coating sharp and the slab protected.
Tasting rooms and bar areas are a different story. Chemical exposure drops dramatically, so a polished concrete finish or standard coated floor works fine and looks better. We design both zones into one retail and restaurant project, with each zone getting its own commercial concrete system.

Installation sequence
How Portland Concrete Builds Brewery Floors
Zone assessment and chemical mapping
We tour the facility with your operations team, identify which areas see acid spills, caustic washdown, hot water, or light exposure, and determine the right system for each zone rather than applying one coating across the whole space.
Slab prep and trench drain installation
The existing concrete is diamond-ground to profile, old coatings and contaminants removed, cracks repaired, and trench drains installed or rebuilt with proper slope to capture washdown water.
Chemical-rated system application
High-exposure zones receive urethane cement (hand-troweled with cove base at walls); moderate zones get chemical-resistant epoxy with broadcast aggregate. Each zone is finished to its exposure spec, not a one-size-fits-all approach.
Verification, cure, and handoff
Floor slopes are checked during install, trench drains are detailed flush and tested, and the production area returns to service after cure. Tasting and bar zones receive their separate finish system on the same timeline.
Washdown reality
Why Trench Drains Are Non-Negotiable
A brewery washdown cycle moves 50+ gallons per minute across the production floor. A single point drain cannot move that volume fast enough. Water pools, sits on the coating, and chemical exposure extends from seconds to minutes. The urethane or epoxy breaks down faster because it is under constant wet stress.
Trench drains across the production zone capture the washdown volume and move it out in seconds. The coating stays dry between cycles, exposure is minimized, and the floor lasts. We design the trench layout and floor slope as one system, then install both together. If your brewery has an adjacent restaurant kitchen, we coordinate the drain systems. See our full retail and restaurant scope for how these projects fit together.
Chemical resistance, trench drains, urethane cement systems and tasting-room finishes.
Because of the chemical exposure. Wort acidity, hot caustic CIP cleaning chemicals, tannic acid in winery operations, and constant wet conditions all degrade standard epoxy. The right brewery floor is a urethane cement or specialized chemical-resistant epoxy system rated for those exposures.
For the production floor, yes, urethane cement handles thermal shock (hot wash on cold floor) and chemical exposure better. Epoxy can work in zones with moderate exposure and proper spec. We pick based on the actual zone exposure, not a default.
For any real brewery production floor, yes. Point drains cannot move the washdown volume; water pools, exposure prolongs, and the system fails sooner. Trench drains across the zone capture and move water fast.
Tasting and bar zones get a different system because the chemical exposure is dramatically lower. Polished concrete or a coated floor is typical there, matched to the brand look. Both systems install in the same project but as separate zones.
Production floor: typically a week or more depending on size, plus cure before returning to service. Tasting and bar zones add a few more days. The schedule is built around your production downtime needs.
Client reviews
What Portland Operations Say About Their Brewery & Winery Floors
Production floor with urethane cement system rated for our CIP chemicals. Three years of brewing, no degradation, washdown cycles work. The trench drains made it possible.
Z. Y2
Brewery Owner, Portland
★★★★★
Acid resistance for wine production zone, polished concrete in the tasting room. Two different systems, clean transition at the doorway. Both have held perfectly.
Y. K2
Winery Operations, Vancouver
★★★★★
They specced for our actual chemical exposure, not the cheapest option. Production floor is solid, no soft spots, no failed seams. Worth the right spec.
Q. M2
Microbrewery Founder, Hillsboro
★★★★★
Trench drains across the production area changed our washdown game. Water leaves in seconds instead of pooling. The floor stays sharp because exposure is short.
