Our Indian Sandstone is aesthetically beautiful and has been selected based on its low water absorption, freeze-thaw durability and flexural strength to prevent splitting. Additionally, you can rest assured that all natural stone from Unilock is sourced from quarries that do not employ child labor. Integrity, safety and fairness are paramount.
