Landscape Inspiration for Your Next Retaining Wall Project
Retaining walls are often more than just an aesthetic addition to your landscaping project. Theyâre used to help control downhill erosion, manage water runoff, and even create usable landscaping space if your green space is steeply graded and difficult to use otherwise. When it comes to building a retaining wall, though, you could be overwhelmed by the number of options available to you.
Kafka Granite knows landscaping stone and can help when it comes to making a unique retaining wall. We offer a variety of granite boulders, cobbles, and decorative rip rapâa large angular stoneâthat can be used to make a one-of-a-kind retaining wall that will blend seamlessly with your natural aesthetic. The variety of naturally colored stone offered make it possible for your retaining wall to become exactly what youâve dreamed of: a beautiful, natural solution that blends in with your landscape rather than obtrusive  manufactured concrete block.
Must-dos for Building a Retaining Wall
When building a retaining wall from natural granite boulders or rip rap, the size of the stone youâll need to build the wall you want will impact your wallâs finished design. If your retaining wall is low and following a particularly curvy course, perhaps around a flowerbed, water feature, or outdoor space, youâre most likely on the lookout for smaller-sized granite boulders. Both boulders and rip rap landscaping stone options can blend into your landscapeâs surroundings or stand on their own as a decorative feature.
As professional designers and contractors, most will be familiar with the retaining wall process. But to err on the side of caution, here are the most important details to keep in mind when plotting out your next retaining wall project outside of the traditional type, color, and size of stone considerations.
Youâll need to have an in depth understanding of where the property lines are located, power lines are buried, and  where there is a difference in grade throughout the area. Knowing the difference in grades within the property will allow you to plan where and how your retaining wall will adjust to the environmentâs natural ebb and flow. With this information you will be able to discuss with your client how they wish to address some of the projectâs challenges. For example, is the final retaining wall going to cut into any hills (and how much material will you have to remove in front of or add behind the new wall) or is it going to follow the natural slope of the property? These conversations will allow all involved to better visualize how the final retaining wall will work in your overall landscape design.
The soil your retaining wall will be holding back is also a vitally important consideration. Soils can range from being clay-based to very sandy. The type of soil used will help determine how much reinforcement your retaining wall will need to provide. Also, a heavy clay soil will provide less drainage than a sandier soil. To ensure optimal drainage and avoid damage from saturation or frost-heave to your retaining wall in the years to come, we recommend using gravel as your primary backfill. When your soil is less than ideal for using behind a retaining wall, using gravel backfill for roughly 2 feet behind the wall is a good solution for drainage. Use gravel backfill until 6 inches below the top of the retaining wall because that is where you can safely fill in with topsoil.
