When it comes to commercial kitchens, your floor system isn’t just about appearance; it’s also about safety, sanitation, durability and compliance. From constant foot traffic and grease spills to extreme temperature fluctuations and sanitation procedures, commercial kitchens must operate under tough conditions.

Before diving into the types of systems, it’s important to understand the key requirements for commercial kitchen flooring: 

• Slip resistance to prevent falls in wet or greasy conditions 

• Seamless surfaces for ease of cleaning and sterilization 

• Durability under heavy foot traffic and rolling equipment 

• Thermal shock resistance from hot equipment and washdowns 

Health departments and other agencies often require the system to be smooth, non-absorbent and easy to clean. 

Kitchen environments are demanding, and floors take a lot of wear. The right floor system has to withstand heavy use, temperature changes, and frequent cleaning day after day.

High-quality commercial flooring is designed to: 

• Handle heavy loads and constant movement without breaking down 

• Resist heat, moisture and aggressive cleaning protocols 

• Streamline cleaning and sanitation processes with seamless finishes

A well-designed commercial kitchen floor creates a safer, more productive environment for your team while helping you stay FDA and USDA compliant for food safety, sanitation and labeling. 

When your floor is working for you,not against you, you’ll notice fewer disruptions, easier maintenance and a more reliable operation overall.

Cementitious urethane, also known as urethane mortar, is a heavy-duty floor system engineered specifically for demanding environments like commercial kitchens. It combines urethane resin with cement and aggregates to create a seamless, extremely durable surface that bonds tightly to concrete surfaces. 

Unlike traditional floor coatings, cementitious urethane is installed at a much thicker build (often 3/8” to ¼”).

• Key Features and Benefits: 

Cementitious urethane is considered one of the most reliable floor systems for wet, high traffic environments because it is built for performance under extreme conditions. 

• Thermal Shock Resistance: Handles rapid temperature changes without cracking or delaminating.

• Moisture Resistance: Performs well in constantly wet environments.

• Chemical Resistance: Withstands grease, oils, acids, cleaning agents and sanitizers. 

• Slip Resistance: Can be textured to improve safety in wet or greasy spaces. 

• Seamless and Sanitary: No grout lines or joints where bacteria can grow. 

• Heavy-Duty Durability: Built for foot traffic, carts or dropped equipment. 

• Long Service Life: Reduces downtime and lifecycle maintenance costs. 

• Installation Methods and Techniques 

Cementitious urethane isn’t a one-size-fits-all. Systems are typically customized based on performance needs. 

1. Trowel-Applied Systems 

   1. Thicker application 

       

   2. Ideal for areas with heavy traffic 

       

   3. Highest level of durability and thermal shock resistance 

       

2. Self-Leveling Systems 

   1. Smoother finish 

   2. Great for large open kitchen or processing areas 

   3. Easier to clean and maintain 

3. Quartz or Aggregate-Filled Systems 

   1. Broadcast quartz or silica for added texture 

   2. Increased slip resistance 

   3. Common in wet or high-safety zones 

4. Cove Base Systems (Integrated Wall Transitions)

   1. Seamless floor-to-wall transitions 

   2. Eliminates corners where bacteria and debris can collect 

   3. Common in health-code regulated environments 

Commercial kitchens aren’t uniform spaces, different areas create very different demands on your floor system. That’s why cementitious urethane systems are often designed and specified by ‘zone,’ ensuring each section of the kitchen is protected based on how it’s actually used. 

• High Heat & Grease Zones (Fryers, Grills & Cooking Lines)

This is one of the most aggressive environments in any kitchen. Floors in these areas are constantly exposed to hot oil, grease splatter, dropped food and intense foot traffic. 

• • Why Cementitious Urethane Works Here: 

    • Superior resistance to fats, oils and grease

    • Withstands high heat without softening or breaking down 

    • Textured finishes improve slip resistance in greasy conditions 

    • Seamless surface helps prevent buildup and contamination 

• Heavy Wash Down Areas (Dish Pits, Cleaning Stations & Sinks)

Washdown zones are constantly exposed to water, steam, detergents and rapid temperature changes from cleaning procedures. 

• • Why Cementitious Urethane Works Here:

    • Exceptional thermal shock resistance 

    • Waterproof and seamless surface 

    • Chemical resistance to cleaning solutions 

    • Can be installed with aggressive non-slip textures for safety 

• Cold Storage Areas (Walk-In Coolers & Freezers)

Cold environments create unique stressors on floor systems due to temperature cycling, condensation and potential ice formation. 

• • Why Cementitious Urethane Works Here:

    • Stable performance in extreme cold conditions 

    • Resistant to cracking from freeze-thaw cycles 

    • Seamless finish prevents moisture infiltration 

    • Durable enough for constant cart and foot traffic

• Prep & Transition Areas (Food Prep, Storage Entry & Corridors)

These are the connective zones of the kitchen where ingredients move between storage, prep and cooking areas. While not always the harshest environments, they experience constant use and cross-contamination risk. 

• • Why Cementitious Urethane Works Here:

    • Seamless, easy-to-clean surface 

    • Durable under heavy traffic 

    • Can be finished smoother for easier daily maintenance 

    • Helps maintain hygiene standards across workflow transitions

1. Safety First

Slip resistance is critical. Floors must maintain traction even with water, grease and oil present to reduce workplace injuries. 

2. Hygiene and Compliance 

Seamless systems reduce bacteria buildup by eliminating grout lines and joints. 

3. Maintenance Requirements 

Commercial floor systems require ongoing proactive maintenance to maintain safety and longevity.

The Advangtages: Floor Repair and Maitnenance
