Every building material faces invisible forces deep within the Earth, and understanding tension stress—the pulling-apart force that fractures rock—reveals why certain natural stones outlast others by centuries. When tectonic plates drift apart or rock masses bend upward, tensile forces create weakness planes that geologists can identify and architects must account for. This geological reality directly impacts your project’s longevity: stones formed under high compression, like granite and dense marble, resist tension better than sedimentary varieties that developed in low-stress environments.
