Floors for Sauce, Pickle & Fermented Food Plants
Vinegar dissolves concrete. So do the brines, tomato acids and lactic acid in sauce, pickle and fermented food plants, and hot kettles and hot-fill lines add thermal shock on top. Floors in these plants pit, then crumble. PumaCRETE urethane concrete flooring resists acetic, lactic and fruit acids, seals salt brine out of the slab, and handles hot spills from kettles and fillers.

What sauces, pickles and ferments do to a floor
Vinegar (acetic acid)
Vinegar dissolves the cement paste in concrete. Pickle and condiment plants that spill it daily lose their floors fast. PumaCRETE resists acetic acid.
Salt brine
Brining and fermenting tanks keep the floor wet with salt that breaks concrete down from inside. A sealed topping keeps it out.
Lactic acid from fermentation
Sauerkraut, kimchi and other ferments produce lactic acid that etches concrete. Urethane concrete resists organic acids.
Tomato and fruit acids
Ketchup, salsa and fruit sauces combine acids with sugar, both hard on concrete.
Hot kettles and hot-fill
Steam kettles, cookers and hot-fill lines put hot product and water on the floor. Thermal zones get 3/8 inch.
Spices and oils
Spice blends and oil-based dressings stain and soften coatings. The sealed surface resists both.
Recommended system by zone
One urethane concrete system, configured for the room you’re standing in. Thickness, texture and cove are set zone by zone. Add 1/8 in for integral cove.
| Zone | Recommended system | Key exposures |
|---|---|---|
| Ingredient receiving and dry storage | 401-HF, 1/4 in | Forklift traffic, spice dust |
| Brining and fermentation tanks | 401-HF, 1/4 in + cove | Salt brine, lactic acid, constant wet |
| Vinegar and acid storage | 401-HF, 1/4 in + cove | Acetic acid, spills |
| Kettles and cooking | 401-HF, 3/8 in (thermal) + cove | Hot product, steam, acids |
| Hot-fill and filling | 401-HF, 3/8 in (thermal), slip-grade | Heat, acidic spills, sugar |
| Labeling and packaging | 401-HF, 1/4 in | Conveyor debris, glass |
Rebuilding acid-damaged floors
Acid-damaged concrete removed
Concrete softened by vinegar and brine is ground back to sound material and patched before the topping goes down.
Phased around production
Tank rooms and lines are done in zones over planned down days.
Drains rebuilt
Drain edges, often the first thing eaten away by acid, are rebuilt and coved.
Food safety and audits

Frequently Asked Questions
Sauces, Pickling & Fermented Foods FAQ's
Acetic acid reacts with and dissolves the cement paste that holds concrete together. Daily spills turn floors rough and pitted, then crumbling. A sealed urethane concrete topping keeps vinegar off the concrete.
Yes. The seamless, non-porous surface supports the sanitation requirements of acidified foods plants under 21 CFR Part 114.
Yes. We specify 3/8 inch around kettles and hot-fill. The system is rated for service up to 248°F.
