Decorative rock, pebbles and stones can be cemented together using mortar and sand to create a sturdy, durable and attractive wall that complements your landscaping. Whether you’re building a retaining wall to beautify your outdoor space or creating a wall that divides your garden or plot of land from the neighbors, use different types of decorative rock to increase the aesthetic appeal of the outdoor space. Here are a few different types of rock that are well-suited for creating an attractive wall or for landscaping projects.
Limestone is a sedimentary rock that contains varying levels of quartz and calcium. Even though limestone is a very soft and porous rock, it is simple to build with, and layers of this rock can create a very strong and durable outdoor wall. Limestone mixed with concrete can be used to create a dry stone wall. The wall can be stabilized with feldstone tips on the corners to create a strong and attractive outdoor wall. Limestone can also be used as a border for pathways and trim around gates or doors.
Crab orchard is a quarried flagstone rock that is usually pink or brown in color. Large, angular pieces of these rocks can be used to create a stacked wall or columns around the outdoor wall. These durable and sturdy rocks can also be stacked with other types of rocks to increase stability of an existing rock wall.
Gray slate can be used as a decorative rock for outdoor walls as an overlay on bricks and other types of rocks. Gray slate has a slight sheen to it so it will reflect sunlight while creating an eye-catching finish. Sheets of gray slate can be cemented directly onto a rock wall, or gray slate rocks and pebbles in their natural form can be stacked on top of each other to create a distinctive design. Gray slate may also be a good fit for trimming doors and gates.
If you want to create an outdoor wall with a Southwestern theme, consider using red shale rocks of different sizes to add some color to the outdoor space. Red shale is available in a variety of shades and can be stacked and cemented in place with colored sand. You can use red shale bricks to create a symmetrical wall, or differently sized red shale boulders and pebbles for a more natural look.
Alberta Rainbow Rock
Alberta Rainbow Rock is available in an assortment of colors and can be purchased in 5 to 80 mm sizes. These decorative rocks have sharp, jagged edges and can be used to create attractive rock walls and borders. When you’ve built a wall with this type of rock, you can use smaller versions of this rock to line a matching pathway, and larger rocks to create a matching ground cover.
