Nut & Specialty Processing Floors Built for Roasting and Allergen Control
Nut, seed and specialty plants deal with heat, oil and allergens. Roasters run hot, nut oils and butters coat the floor, salt and seasonings are abrasive, and low-moisture foods require tight control of Salmonella and allergen residue. PumaCRETE urethane concrete flooring resists roaster heat and oils, and gives you a seamless floor that cleans completely between products.

What nut and specialty processing do to a floor
Roaster heat
Roasters radiate heat onto the floor and hot product spills when trays and coolers are emptied. Thermal zones get 3/8 inch.
Nut oils and butters
Peanut, almond and other oils soften coatings and make floors slick. Urethane concrete resists oils.
Salt and seasoning
Salt and seasonings are abrasive and corrosive to concrete. A sealed topping keeps them out of the slab.
Allergen control
Peanut and tree nut residues must be removed completely between products. There are no joints or cracks for residue to hide in.
Low-moisture food sanitation
Dry nut and seed areas are cleaned with minimal water to control Salmonella. PumaCRETE’s smooth surface cleans well dry.
Dust from shelling and sizing
Hulling, shelling and sizing release dust and debris. A seamless floor sweeps clean.
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 |
|---|---|---|
| Receiving, hulling and shelling | 401-HF, 1/4 in | Dust, debris, forklift traffic |
| Sorting and sizing | 401-HF, 1/4 in | Dust, cart traffic |
| Pasteurization and roasting | 401-HF, 3/8 in (thermal) | Heat, hot product, oils |
| Nut butter and paste milling | 401-HF, 1/4 in + cove, slip-grade | Oils, butters, washdown |
| Seasoning and coating | 401-HF, 1/4 in | Salt, seasoning, oils |
| Packaging | 401-HF, 1/4 in | Conveyor debris, cart traffic |
Installing in a dry plant
Dust contained
HEPA extraction keeps prep dust away from product and packaging.
Dry zones protected
Installation is planned so water and moisture stay out of low-moisture product areas.
Phased by line
Lines are done during shutdowns, with the rest of the plant in production.
Food safety and audits
- Meets FDA current good manufacturing practice: floors that can be adequately cleaned and kept in good repair (21 CFR Part 117)
- Seamless surface supports allergen cleaning and Salmonella control in low-moisture areas

Frequently Asked Questions
Nut & Specialty Processing Floors FAQ's
Peanut and tree nut residue lodges in cracks and joints and survives cleaning. A seamless floor removes those spots so changeover cleaning is complete.
Yes. The smooth surface sweeps and vacuums clean, which suits low-moisture areas where water is kept to a minimum to control Salmonella.
Yes. We specify 3/8 inch around roasters. The system is rated for service up to 248°F.
In oil-heavy areas we use a slip-grade texture, and the sealed surface releases oil under normal cleaning.
