Decomposed granite has become a popular material in landscaping, paving, and many outdoor projects for all the good reasons. Its durability and ability to absorb water have made it useful for various purposes. This material comes in colors like gray, brown, gold, and red, all of which complement every design layout. So if you are thinking about using decomposed form of granite to use for your outdoor renovation projects, believe that you are making the right decision. What’s better than crushed granite particles to make a pathway for a park, or garden or any other area? But you should know everything about decomposed granite, including its installation process, to make good use of it.
Let’s discuss everything about decomposed granite in this guide:
What is Decomposed Granite?
Decomposed granite is essentially granite that has undergone a process of erosion over thousands of years, which makes it a sustainable and eco-friendly option for landscaping projects. In other words, it is a type of granite rock that has been naturally weathered and broken down into smaller particles, usually ranging from fine dust to small gravel-sized pieces. It’s often used as a ground cover in gardens, pathways, patios, and driveways.
When crushed and processed, the granite creates a loose, compacted material that provides a natural look and texture, making it perfect for creative outdoor spaces.
How to Install Decomposed Granite?
The process to install decomposed granite is so easy that even a beginner can do it very easily. Just follow these instructions accurately and create whatever you want to make.
Gather the Materials Needed:
- Decomposed granite (available in different grades depending on your project needs)
- Landscape fabric (optional, but helpful for weed control)
- Crushed rock or gravel (for the base layer)
- Shovel and rake
- Wheelbarrow
- Compactor or hand tamper
- Edging material (optional, for defined borders only)
Install Decomposed Granite in 7 Simple Steps
Prepare the Area
To prepare the area, you need to make a proper plan. For example, choose the area where you want to install decomposed granite and then select the size. Use paint, strings, or stakes to outline the area. Also clear the area in case there is any garbage, grass, weeds, plants, or any other things. It’s a crucial step that ensures the entire surface is leveled, and you will not face any difficulty during installation.
Excavate the Area
Dig down to a depth of about 3–4 inches to create a stable base for the decomposed granite. This is just a general depth; if you need, you can make the base deeper. For this purpose you need to use a shovel or any other digging tools. Make sure that the surface is flat and the granite particles are sufficient to fill the base you are creating.
Add a Base Layer
Before filling in the completely decomposed granite, create a base layer using rocks or gravels in crushed form. This will not only save much of the granite particles but also provide a more stable base. However, you should ensure that rocks are spread equally. For that purpose, you can use a hand tamper or a compactor. Apply some pressure to the tamper, and everything will be distributed evenly.
Install Landscape Fabric (Optional)
Install a landscape fabric to prevent weed formation, which is a problem faced by many people. You can prevent that with the use of the right fabric. Landscape fabrics are also famous as garden or weed fabrics. These fabrics prevent the growth of weed, grass and many other plants. If you want to keep your work looking clean and tidy, you should install such fabrics.
Method to install landscape fabric:
The method to install fabric is very basic. It includes these steps:
- Clear the area.
- Spread the fabric.
- Overlap the edges of the fabric to ensure complete coverage.
- Secure fabric using nails, pins, and staples.
- Trim extra fabric.
Spread the Decomposed Granite
Spread the decomposed granite using tamping tools and shovels. You can just pour the partially or completely decomposed granite particles and then spread them thoroughly. Furthermore, make sure to aim for a thickness of at least 2-3 inches while pouring the granite. Don’t put so much that even the particles keep falling in the surrounding area.
Add Edging
Create beautiful edges using bricks, stones, pebbles, wood, bamboo, rubber, or plastic and metal materials. This will give a structured look to the landscaping design. Arrange the materials neatly around the borders to make it look even more attractive. Moreover, you can use different patterns, such as zigzag, circular, or any other symmetry that you like.
Final Touches
After the installation is complete, give your project a final inspection to ensure the surface is level and compact. You may want to add an additional thin layer of decomposed granite and recompact it for a smooth, finished look. Moreover, check for the accuracy of edges to make sure everything looks perfect.
Post Installation Care:
After a perfect installation of decomposed granite, keep it looking its best. You can do it with three simple practices:
- Rake it occasionally: Over time, the surface may start to shift. Use a rake to level the material and prevent any unevenness.
- Recompaction: If the surface becomes too loose, recompact it by using a hand tamper or compactor.
- Weed control: While decomposed granite helps with drainage, weeds can still sprout up. Regularly remove any weeds by hand or with a weed killer.
Conclusion:
Decomposed granite contains crushed granite particles that are sustainable and look great in every outdoor space. It is the minimum investment that you can make to enhance the natural aesthetics of a garden, park or driveway. Moreover, completely decomposed granite installation is also an enjoyable process. That’s because you can do it using basic tools and minimal work. Once you know the proper method and post-installation care tips, you can design all sorts of outdoor decorations using granite.
