Ndarugo manual cut stones, also known as foundation stones, are hand-cut building stones sourced from Ndarugo quarries in Kenya. These stones are preferred for constructing house foundations due to their durability, strength, and excellent load-bearing capacity. They are manually shaped to achieve a rough texture, ensuring strong bonding with mortar and stability for the entire structure. Ndarugo stones are naturally dense, weather-resistant, and cost-effective, making them ideal for both residential and commercial buildings. Commonly sized at 6x9 or 9x9 inches, they provide a reliable base, ensuring long-term structural integrity and resistance to environmental stress.
