Winery Flooring Requirements: What Each Room Has to Handle

By Pablo Figueroa · October 19, 2026 · 4 min read

A winery is a wet building with acid in it, forklifts moving through it, and a season that cannot be moved. The floor is the surface all of that happens on, and the requirements change from room to room.

What does a winery floor have to handle?

Four things at once. Water, because a working winery washes its floors and its equipment constantly, and everything that is washed ends up in a drain. Acid, from the grapes and from the cleaning program. Wheeled loads, from forklifts, bins, pallets and barrel handling. And people, who need grip on a floor that is wet more often than dry.

DTI's site describes its food and beverage floor systems as built for thermal shock and caustic washdowns. A tank room that gets hot water and cleaners is a good example of why that matters.

Is there a code that sets winery floor requirements?

Not a single one. The requirements come from several places: your local building and environmental health offices, your wastewater permit, the winery's own cleaning program, and the equipment that runs on the floor. In California, regional water boards issue waste discharge requirements for winery process water, so where the water goes is regulated as well as designed. Ask your local offices what applies to your site before a system is chosen.

How acidic is a winery, really?

UC Davis's Waterhouse Lab lists typical wine concentrations of 1,000 to 4,000 mg/L tartaric acid and 0 to 8,000 mg/L malic acid, while noting that levels vary greatly. These figures describe wine composition, not a floor coating's chemical-resistance rating.

The cleaning program adds different chemical exposures. UC Davis's winery chemical guidance describes citric acid and peracetic acid, as well as alkaline cleaners. Caustic potash is potassium hydroxide, a strong alkali, not an acid. Cleaning chemicals can present a different or more demanding exposure than wine, depending on the product, dilution, temperature and contact time; they should not all be treated as acid exposure.

A 2023 study of ordinary Portland cement mortar tested acetic, citric, lactic and propionic acids at 5%, 10% and 15% weight/volume concentrations. Its published abstract reports greater degradation in citric and lactic acids than in acetic and propionic acids. These laboratory immersion results demonstrate a risk to cement-based materials, but do not predict the service life of a winery floor or establish the resistance of a resin coating.

The practical step: list every cleaning and sanitizing product, its actual use concentration, temperature, dwell time and frequency, along with wine and other process exposures. Check the exact proposed flooring system against its manufacturer's current chemical-resistance data and obtain written confirmation for the actual conditions. For example, Sika's Sikafloor-511 chemical-resistance chart distinguishes chemicals, concentrations and exposure periods, with tests at 20°C; it is an example of product-specific data, not a recommendation of that product for every winery. Do not assume a room-temperature rating covers hot washdowns, or that a rating for one ingredient covers a blended cleaner. Follow the cleaner's label and safety data sheet; do not mix cleaning chemicals.

Does every room need the same floor?

No, and a single system across the building is the most common mistake. The crush pad needs slope, traction and drains that take forklift traffic. The tank room needs cove base, drain detailing and resistance to hot washdowns. The barrel room is cool and damp, with stacked racks. Bottling and case storage run like a warehouse. The tasting room is judged by how it looks, and acidic liquids can etch unprotected polished concrete.

How long does a winery floor take to install?

DTI's typical timelines are about 24 hours to foot traffic and 48 to 72 hours to vehicle traffic, depending on product and conditions. The calendar matters more. A California crush season typically runs about 120 days between August and November, so the install window is the rest of the year, and it ends on the day the first bin arrives. Plan moisture testing, prep, cure and a buffer for an early harvest.

What should be in writing before a winery floor is installed?

• A zone map listing each room, its exposures and its traffic
• The cleaning program: products, concentration, temperature, dwell time and frequency
• Slope to drain in inches per foot, and a water test before coating
• Drain and trench details, including where the coating ends
• Moisture test results by zone
• A schedule worked back from the first day of fruit
