Outdoor flooring has to withstand a lot: extreme temperature fluctuations, heat, cold, and frost. With conventional surfaces like ceramic tiles, moisture can seep through the joints. This can cause tiles to come loose over time due to frost pressure in winter or vapor pressure in summer.
That’s not an issue with stone carpet. Thanks to its open-pored structure, water drains away easily — preventing puddles, chipping, or cracks, even after many years.
