Meaning
Industrial concrete slab designed for facilities where vehicle traffic follows non-defined or random paths across the entire surface. Warehouses with wide aisles often require a free movement floor to allow forklifts to turn and operate in any direction without hitting surface irregularities. The specifications for these slabs focus on overall flatness and levelness rather than specific wheel paths.
Traffic Distribution
Pattern of vehicle activity within a storage or manufacturing zone. Because trucks travel anywhere on a free movement floor, the entire surface must meet a uniform standard of smoothness. This contrasts with defined movement areas where only specific tracks are measured.
Operational Utility
Effectiveness of the floor surface in supporting logistics and production. A high-quality free movement floor reduces the wear on vehicle tires and suspension systems. It also allows for flexible storage layouts that can change as inventory needs evolve.
Surface Specification
Technical criteria for measuring the quality of a concrete slab. Testing a free movement floor involves measuring a grid of points to calculate the flatness and levelness values known as f-numbers. Higher numbers indicate a smoother surface that permits faster vehicle speeds and safer high-level stacking.
If the floor fails to meet these values, the facility operator faces increased maintenance costs and lower productivity. Precision grinding sometimes becomes necessary to bring a substandard slab into compliance.
