What are the best stone types for outdoor seating in areas with high seismic activity?
When selecting stone for outdoor seating in areas with high seismic activity, durability and flexibility are key. The best options include granite, basalt, and slate due to their high compressive strength and resistance to cracking. Granite is particularly favored for its density and ability to withstand ground movement. Basalt offers excellent durability and a non-slip surface, while slate provides a lightweight yet sturdy alternative. Avoid porous stones like sandstone, as they are more prone to fracturing. Proper installation with flexible joints can further enhance seismic resistance, ensuring long-lasting safety and functionality.
