Light Grey Guillotined armour stone is natural stone that has been mechanically split using a hydraulic guillotine to create flat faces and consistent widths. This process produces large, stackable blocks with a natural split texture while allowing for clean, uniform installation. Guillotined armour stone is commonly used for retaining walls, garden borders, terraces, and landscape accents. Its consistent sizing makes installation easier while maintaining the natural look and strength of quarried stone.
