Armour stone is a natural rock that is used to shield shorelines and river beds, and is known for its durability and resistance. Armour stones are known for their beauty and boldness, and are perfect for a variety of landscaping designs. Armour stones do not crack or erode. We use armour stones to build retaining walls, steps and everything we possibly can. Armour stones ensure the absolute best for your property through interlocking, retaining walls and everything you need for your landscaping needs.
