What are the risks of using untreated stone in outdoor seating near water features?

Using untreated stone for outdoor seating near water features may seem aesthetically pleasing, but it comes with significant risks. First, prolonged exposure to water can cause erosion, weakening the stone's structural integrity and leading to cracks or breaks. Second, moisture promotes algae and mold growth, creating slippery surfaces that pose safety hazards. Additionally, untreated stone is more susceptible to temperature fluctuations, which can cause expansion and contraction, further damaging the material. Over time, these factors may result in costly repairs or replacements. To ensure durability and safety, consider sealing or treating the stone or opting for weather-resistant alternatives like treated wood or composite materials. Proper maintenance and material selection are key to long-lasting outdoor furniture near water features.
