In food and beverage facilities, safety and performance go hand in hand. Floors, equipment, and infrastructure all play a role in maintaining sanitary, efficient environments. One factor that often gets overlooked—but can have serious consequences—is thermal shock.
Thermal shock happens when surfaces experience sudden and extreme temperature changes. In a food and beverage facility, that might mean hot water from a sanitation hose hitting a cold concrete floor, or freezers thawing during a washdown. These temperature swings can lead to cracking, delamination, and even floor failure if the right precautions aren’t taken.
At CustomCrete, we’ve helped many Chicago-area businesses in the food and beverage industry address the risks of thermal shock through smarter flooring systems and coatings. In this article, we’ll explain what thermal shock is, why it matters, and how you can protect your facility from damage.
What is Thermal Shock?
Thermal shock occurs when a surface undergoes rapid temperature change—usually from hot to cold or vice versa. Concrete and other flooring materials expand and contract with temperature shifts. When those changes are sudden, the material can’t adjust evenly. This results in internal stress, cracking, and long-term structural damage.
In food and beverage settings, thermal shock is often caused by:
- Hot water or steam cleaning
- Exposure to freezing temperatures followed by thawing
- Cold storage areas being opened frequently
- Direct discharge of hot liquids or chemicals onto the floor
Why It Matters in Food and Beverage Facilities
Facilities that process food and drinks must meet strict hygiene standards while also maintaining efficient operations. Floors play a major role in both of these goals—and they take a beating from both mechanical and thermal stress.
Here’s why managing thermal shock is essential:
1. Prevents Cracking and Surface Damage
Frequent thermal cycling can cause surface delamination, spalling, or large cracks. These issues not only look bad but can become safety hazards and contamination sites.
2. Maintains Sanitary Conditions
Damaged floors harbor bacteria, mold, and debris in cracks or gaps. In food and beverage settings, that puts your facility at risk of regulatory violations and product contamination.
3. Reduces Downtime and Repairs
Once thermal shock damage starts, it spreads quickly. Replacing or repairing floors interrupts production and costs more in the long run than prevention.
4. Supports Compliance and Safety Standards
Agencies like the USDA and FDA expect surfaces in food processing areas to be smooth, seamless, and easy to clean. Flooring that fails under thermal stress can lead to compliance issues.
How to Protect Against Thermal Shock
The best way to deal with thermal shock is to prevent it through the right floor systems and installation methods. Here are a few effective strategies:
1. Use Urethane Cement Systems
Urethane cement is one of the best materials for handling thermal shock. It can withstand sudden temperature changes ranging from -50°F to over 200°F without cracking or delaminating.
2. Avoid Thin Coatings in High-Impact Zones
Thin coatings or sealers often don’t provide enough protection in food and beverage environments. Use thicker, industrial-grade systems in areas where temperature swings are common.
3. Include Slip-Resistant Additives
While not directly related to thermal shock, slip resistance becomes even more important when water or cleaning agents are involved. A textured finish helps reduce safety risks.
4. Work with Experienced Installers
A contractor familiar with food and beverage standards can recommend materials, thicknesses, and prep methods that ensure long-term performance and code compliance.
High-Risk Zones in Food and Beverage Plants
Some areas in a facility are more prone to thermal shock than others. Pay close attention to:
- Washdown zones where hot water and chemicals are regularly used
- Freezers and cold storage where condensation or defrosting occurs
- Drainage areas exposed to temperature fluctuations
- Bottling or cooking lines with high heat or liquid discharge
Knowing where the risks are helps prioritize repairs or upgrades before problems emerge.
Final Thoughts
Thermal shock may not be the first thing you consider when evaluating your facility’s flooring, but it can have serious long-term consequences if ignored. By understanding how temperature changes affect your concrete and coatings—and choosing materials designed to withstand those stresses—you can keep your operations running smoothly, safely, and in compliance.
At CustomCrete, we help food and beverage facilities across Chicago select and install floor systems that stand up to both mechanical and thermal stress. Whether you need a urethane cement overlay or moisture barrier prep, we can guide you toward the right solution for your space.
