The Cement Slab: Foundational Considerations for Meat Plant Design

See the Floor: The Floor of the Meat Factory

When designing a meat plant, the cement slab is the foundation that supports both the structure and the day-to-day operations. It must meet strict hygiene, safety, and functionality standards, especially when handling heavy equipment and maintaining cleanliness. Below is a detailed guide on the construction and key considerations for the cement slab, including flooring, drainage, isopanel walls, door openings, and protective cladding.

1. The Floor of the Meat Factory

The floor is critical to ensuring that the meat plant runs efficiently and remains hygienic. A durable, non-porous surface is essential to withstand the heavy machinery and frequent cleaning required in a meat processing facility.

Recommended Flooring:

  • SpecFloor 1K SF Silane Hybrid Floor Coating Gloss Clear with SpecFloor 1K SF Silane Hybrid Floor Coating is the ideal choice for this environment.
  • This coating provides excellent resistance to chemicals, wear, and heavy traffic. It ensures the floor is easy to clean and minimizes the risk of contamination.

The choice of this flooring is especially suited for meat plants where cleanliness is paramount. The SpecFloor 1K SF coating offers an ultra-durable surface that can handle the wet conditions and rigorous sanitation routines of a meat factory.

2. Erecting the Steel Frame and Wall Construction

A steel frame is erected on the cement slab to provide the necessary support and flexibility for the plant. The frame allows for easy adjustments or expansions to the facility, ensuring that as the business grows, the plant can adapt.

Isopanels will be used for both exterior and interior walls:

  • Exterior Isopanel Thickness: Minimum 100mm thick for superior insulation, especially around chillers, freezers, and temperature-sensitive areas.
  • Interior Isopanel Thickness: Minimum 80mm thick, ensuring proper separation between workspaces while maintaining easy-to-clean surfaces.

Movable Walls: The interior isopanel walls will be sealed to the floor but not embedded in it. This ensures the walls can be repositioned without the need to redo the flooring, allowing for a modular design that evolves with the facility’s requirements.

3. Door Openings: Sizing and Types

Proper door sizing and configuration are crucial for maintaining an efficient workflow within the plant. This is especially important for areas that frequently handle pallet jacks and forklifts.

  • Standard Pallet Dimensions: 1.2m x 1.0m
  • Recommended Door Width: At least 1.8 meters wide to accommodate pallet jacks, which is 1.5 times the width of a pallet.

The plant will feature two main types of doors:

  • Swing Doors with Crash Bars: Installed in high-traffic areas. The crash bars prevent damage from collisions with equipment, ensuring the doors remain functional over time.
  • Sliding Doors: Used in areas with limited space or high-volume traffic, such as between chillers, freezers, and processing areas.

4. Drainage and Floor Slopes/Levels

Effective drainage is essential for maintaining hygiene, and proper floor slopes are required to direct water toward designated drains. The floor must be slightly sloped to ensure all liquids flow efficiently into the drains, preventing pooling and potential contamination risks.

Internal Drainage: Drains will be placed strategically in all high-use areas, including processing, deboning, washing bays, and slaughtering lines. All drains will feature grates to prevent debris buildup.

External Drainage: Just as important as internal drainage, the external system must handle large volumes of water, particularly around areas like the truck wash bay. Rainwater management is critical to avoid flooding and ensure clean conditions around the plant.

5. Rubber “Crash Bar” Cladding

To protect the walls from damage caused by equipment and machinery, rubber “crash bar” cladding will be installed at a height of 750mm along the walls. This cladding is essential in areas with high equipment traffic, such as the deboning and processing halls, where pallet jacks and carts are frequently in use.

This cladding provides both protection for the walls and safety for the employees, as it absorbs impact and prevents unnecessary damage, reducing maintenance costs over time.
