About this research
Compares the slip potential of natural and manufactured stone flooring finishes, showing how substantial changes in surface finish affect performance when wet.
How the research was conducted
HSL characterised a selection of stone flooring ramp boards using wet pendulum testing and Rz roughness measurements, covering finishes including polished, honed, riven and textured examples.
Main findings and significance
The tests distinguished materials with high, moderate and low wet slip potential. Several polished stone finishes were identified as high risk, while more textured finishes often performed better. The two measurement approaches provide complementary evidence.
Interpretation and limitations
Stone type alone is not a reliable proxy for slip resistance: the surface finish and contamination conditions matter. Results refer to the historical samples tested.
