The Biggest Hidden Danger in Cold Storage: Heat from the Ground and Frost Heave
In industrial cold storage investments, the focus is almost always on the walls, ceiling insulation, and refrigeration units. Choosing high-quality PUR panels and the right compressors is undeniably crucial. However, beneath the foundation lies a hidden threat that is often overlooked and can lead to massive destruction over time: Heat from the ground and the Frost Heave effect.
What is Frost Heave? Particularly in freezer rooms (-18°C and below), the extreme cold air gradually penetrates through the concrete floor and into the underlying soil. The moisture and groundwater present in the soil begin to freeze under this continuous exposure to sub-zero temperatures. When water freezes, it expands by approximately 9% in volume. This continuous icing and expansion beneath the surface create an immense hydraulic pressure that begins to push the multi-ton concrete floor upward.
What are the Consequences?
-
Floor Cracking and Heaving: The concrete floor cannot withstand this massive pressure and cracks.
-
Panel and Insulation Damage: Shifts in the floor level force wall panel joints to separate, creating thermal bridges and compromising the entire insulation envelope.
-
Structural Failure: In advanced cases, the load-bearing columns and the structural integrity of the facility can suffer permanent damage. This can be severe enough to render the entire investment unusable.
The Solution: A Comprehensive Engineering Approach with Karsey Industry Solving this problem is not as simple as "pouring thicker concrete"; it requires scientific insulation and engineering planning. High-compressive-strength XPS insulation boards must be laid beneath the concrete, proper vapor barriers must be utilized, and crucially, for sub-zero rooms, underfloor heating systems (glycol tubing or electrical heating mats) must be integrated.
Since 2000, with 26 years of industry experience, Karsey Industry is not merely a panel manufacturer; we provide comprehensive engineering solutions that design your facilities as a cohesive whole. While we provide flawless thermal insulation for your walls and ceilings using our high-density PUR-filled panels (manufactured without heating the sheets to preserve optimal structural integrity), we also stand by you with the technical consultancy and correct project design needed to secure your investment at the foundation level. If the foundation of your cold storage is solid, its future is solid.
