Edible Oil Refinery & Rendering Plant Floors
Oil and fat plants put more grease on the floor than anywhere else in food processing. Hot oils and free fatty acids soften coatings and make floors dangerously slick, caustic refining splashes lye, and rendering plants add raw animal by-products, cookers and heavy loaders. PumaCRETE urethane concrete flooring resists oils, fatty acids and caustic, and holds a slip-resistant texture.

What oil and fat processing do to a floor
Hot oils and fats
Hot vegetable oils and animal fats soak into concrete and soften coatings. Urethane concrete resists oils and fats.
Free fatty acids
As fats break down they form fatty acids that attack concrete. PumaCRETE resists organic acids.
Caustic refining
Neutralization uses caustic soda, which splashes and drips onto the floor. The system is designed for caustic exposure.
Slip risk
Oily floors are among the most dangerous in any plant. Slip-grade texture keeps the wet coefficient of friction in the 0.6–0.9 range.
Raw material at rendering plants
Rendering receiving handles raw animal by-products with heavy loaders. Thicker, textured systems handle the abuse.
Cooker and press heat
Cookers, presses and deodorizers bring heat and steam. Thermal zones get 3/8 inch.
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 |
|---|---|---|
| Rendering raw material receiving | 401-HF, 3/8 in + cove, slip-grade | Raw by-products, loaders, organic acids |
| Cookers and presses | 401-HF, 3/8 in (thermal) + cove | Heat, fats, steam |
| Oil refining and neutralization | 401-HF, 3/8 in + cove | Hot oil, caustic, fatty acids |
| Bleaching and deodorizing | 401-HF, 3/8 in (thermal) | Heat, oil, spent bleaching earth |
| Filling and packaging | 401-HF, 1/4 in, slip-grade | Oil spills, conveyor traffic |
| Tank farm and loading | 401-HF, 1/4 in | Oil spills, truck and forklift traffic |
Installing on oil-soaked slabs
Oil-contaminated concrete prepared
Oil-soaked concrete is cleaned and ground back to sound material so the topping bonds.
Phased by area
Refining, packaging and rendering areas are done in zones so the plant keeps running.
Texture tuned for oil
Coarser aggregate where oil is heaviest, finer texture where carts roll.
Food and feed safety

Frequently Asked Questions
Edible Oil Refinery & Rendering Plant Floors FAQ's
Usually, yes, after the contaminated surface is cleaned and ground back to sound concrete. We test bond during the site visit.
We use a coarse slip-grade texture in oil-heavy areas. Wet coefficient of friction runs 0.6–0.9 depending on texture, and the sealed surface releases oil under cleaning.
Yes. PumaCRETE is designed for caustic exposure. We specify 3/8 inch with integral cove in neutralization areas.
Yes. See the Meat & Poultry pages for kill floor and processing areas.
