Are you looking for an affordable and attractive way to spruce up your outdoor space? Look no further than decomposed granite! This versatile material is a popular choice for pathways, driveways, and even garden beds. In this step-by-step guide, we’ll show you how to install decomposed granite like a pro.
Preparation

Before you begin installing decomposed granite, it’s important to properly prepare the area. Here’s what you’ll need:
Tools and Materials Needed
- Shovel
- Wheelbarrow
- Rake
- Tamper
- Decomposed granite
- Stabilizer (optional)
Site Preparation
Start by clearing the area of any plants, rocks, or debris. If you’re installing decomposed granite over an existing surface, such as concrete or asphalt, you’ll need to remove any loose material and ensure the surface is clean and dry.
Measuring the Area
Measure the area you’ll be covering with decomposed granite to determine how much material you’ll need. To do this, multiply the length by the width to get the square footage. Be sure to add an extra 10-20% to account for settling and compaction.
Once you have your measurements, it’s time to order your decomposed granite. You can typically purchase it by the cubic yard or ton, depending on the supplier.
Installation
Now that you’ve prepared the area, it’s time to start installing your decomposed granite. Follow these steps:
Laying the Base
If you’re installing decomposed granite over an existing surface, skip to the next step. If you’re starting from scratch, you’ll need to create a base layer using crushed rock or gravel. This will help with drainage and prevent the decomposed granite from sinking into the soil.
Spread the crushed rock or gravel evenly over the area, using a rake to smooth it out. Use a tamper or plate compactor to compact the base layer, ensuring it’s level and stable.
Spreading the Decomposed Granite
Now it’s time to spread the decomposed granite over the base layer. Use a shovel or wheelbarrow to transport the material to the installation site. Spread it evenly with a rake, ensuring a depth of 2-3 inches.
If you’re using a stabilizer, now is the time to apply it. This will help to bind the decomposed granite together and prevent it from shifting over time.
Compact the Surface
Use a tamper or plate compactor to compact the decomposed granite, starting at the edges and working your way inward. This will help to create a stable and level surface.
Congratulations, you’ve successfully installed decomposed granite! In the next section, we’ll discuss how to maintain your new surface.

Laying the Base (Continued)
If you’re installing decomposed granite on a slope, you’ll need to create terraces to prevent the material from sliding down. To do this, use a shovel to create a small retaining wall at the bottom of the slope, and then spread the base layer over the top.
Spreading the Decomposed Granite (Continued)
If you’re installing decomposed granite on a slope, start at the bottom and work your way up. Spread the material in thin layers, using a rake to even it out as you go. This will help to prevent the material from sliding down the slope.
Compact the Surface (Continued)
Once you’ve finished spreading the decomposed granite, use a tamper or plate compactor to compact the surface. Be sure to work in small sections, starting at the edges and working your way inward. This will help to create a stable and level surface.
Maintenance
Now that you’ve installed your decomposed granite, it’s important to take proper care of it to ensure it lasts for years to come. Here are some tips for maintaining your new surface:
Regular Cleaning
To keep your decomposed granite looking its best, you’ll need to regularly sweep or rake it to remove any debris or leaves. You can also use a leaf blower to make the job easier. This will help to prevent the material from becoming compacted and ensure proper drainage.
Repairing Damages
If your decomposed granite becomes damaged, such as by erosion or heavy foot traffic, it’s important to repair it as soon as possible. Start by removing any loose material, and then add more decomposed granite as needed. Use a tamper or plate compactor to compact the surface and ensure it’s level.
Resealing the Surface
If you’ve used a stabilizer to install your decomposed granite, you’ll need to reapply it every year or two to maintain its effectiveness. Follow the manufacturer’s instructions for best results. If you haven’t used a stabilizer, you can apply a sealer to help prevent the material from staining or fading over time.
By following these maintenance tips, you can ensure your decomposed granite looks great for years to come. Congratulations on your new outdoor surface!
Tips and Warnings
While installing decomposed granite is a relatively straightforward process, there are a few tips and warnings to keep in mind:
Proper Use of Tools and Equipment
Be sure to use the proper tools and equipment when installing decomposed granite. This includes a shovel, rake, tamper, and plate compactor. Using the wrong tools can result in an uneven surface or damage to your equipment.
Safety Precautions
Always wear appropriate safety gear, such as gloves and eye protection, when working with decomposed granite. Use caution when operating heavy equipment, such as a plate compactor, and be sure to follow all manufacturer instructions.
Environmental Considerations
When choosing decomposed granite, consider its impact on the environment. Some types of decomposed granite may contain harmful chemicals or heavy metals, so be sure to research the material before making a purchase. Additionally, be mindful of how water runoff from the decomposed granite may affect nearby plants or water sources.
Conclusion
In conclusion, installing decomposed granite is a cost-effective and attractive way to enhance your outdoor space. By following the steps outlined in this guide, you can create a stable and level surface that will last for years to come.
Some benefits of installing decomposed granite include its affordability, low maintenance requirements, and versatility. It can be used for a wide range of outdoor projects, from pathways and driveways to garden beds and patios.
If you’re considering installing decomposed granite, we recommend doing your research and choosing a reputable supplier. With the right tools, materials, and techniques, you can create a beautiful and functional outdoor space that you’ll enjoy for years to come.
