Urethane Concrete
Cementitious urethane systems built for thermal shock, moisture tolerance, and the harshest food-processing and industrial environments — where epoxy can't survive.
Cement-modified urethane
Urethane concrete (also called urethane mortar or urethane cement) is a hybrid system: a polyurethane resin reacts with an aggregate-filled cement powder to form a thick, monolithic floor that behaves more like reinforced concrete than a thin coating. Typical build runs 125-375 mils — three to ten times thicker than standard epoxy.
That thickness, plus the cementitious matrix, gives urethane concrete properties no thin coating can match. It cures over damp slabs that would fail an epoxy install. It survives rapid temperature swings from freezer to steam clean-down without cracking. And it shrugs off the chemicals, hot water, fats, and acids that destroy standard floors.
Where urethane concrete shines: food and beverage processing, dairies, breweries, commercial kitchens, chemical plants, automotive bays, and any environment where thermal cycling or aggressive cleaning protocols would shorten the life of an epoxy system.
Where urethane concrete wins
Food & Beverage Processing
USDA/FDA-compliant systems engineered for hot water washdowns, steam, animal fats, sugars, and lactic acid. Thermally stable from freezer floors to baking and rendering environments.
Thermal Shock Resistance
Rapid cycling from 0°F freezers to 200°F+ clean-down. Will not crack or delaminate where epoxy systems fail under thermal stress.
Heavy-Duty Industrial
Chemical plants, automotive bays, manufacturing floors. Hot-tire pickup, dropped tools, forklift traffic — built for the abuse epoxy can't handle.
Moisture-Critical Slabs
Installs over damp concrete that would fail an epoxy bond test. Built-in vapor tolerance often eliminates the need for a separate moisture mitigation layer.
Back in service fast
Cure schedule varies by system, build thickness, and ambient temperature. Heavier industrial mortars take longer to reach full chemical resistance; thinner self-leveling builds open to traffic faster.
Urethane concrete is built for what epoxy can't survive
Honest tradeoffs
Urethane concrete is overkill for residential garages and most light commercial spaces. It costs more per square foot than epoxy and installs as a thick monolithic build, so it's the right call only when the environment actually demands its performance characteristics.
For everyday garage, retail, and light-commercial work, epoxy paired with a UV-stable topcoat is the better answer. Urethane concrete is specified when thermal shock, moisture, aggressive chemicals, or heavy industrial abuse demand it. It also performs exceptionally as a base layer under metallic, flake, or other decorative finishes when extended lifespan matters.
How long it lasts
- Food processing (proper detailing): 15-20+ years
- Heavy industrial & chemical: 10-15 years
- Thermal-shock cycling: 10-15 years, unaffected by freeze-to-steam cycles
Pair with the right system
Thermal shock, food-grade, or heavy-industrial?
If your floor sees freezer-to-steam cycling, hot caustic washdowns, or chemical abuse, urethane concrete is the answer.
