"Natural Stone: The Ultimate Long-Term Solution
Granite - The Premier Choice
Granite emerges as the most durable building material for extreme longevity . This igneous rock offers exceptional properties for Nordic climates:
Freeze-thaw resistance: Granite's dense structure and low water absorption rate (typically less than 0.5%) make it virtually immune to frost damage
Durability span: Granite can withstand some of the harshest environments with relatively little upkeep for centuries
Temperature stability: It resists expansion and contraction during extreme temperature variations, minimizing cracking risks "
