Decomposed granite or DG is a popular construction material made of finer and more stable gravel. These types of gravel materials resulted from the erosion and weathering of tough and igneous solid granite. The particle is at most ⅜ inch in size with a grain of sand bigger than most of these particles. This is also the reason why it’s also known as crushed granite.
DG comes in a variety of colors, giving you more options to consider for your patio. From different shades of gray and brown to green and red, you can choose the color that will match the idea you envision for the backyard design. This also makes decomposed granite an incredible material.

• Garden trails/paths
• Ground cover
• Garden-to-wilderness transition

The decomposed granite also needs to be distanced (not too close) to your home’s entryway, especially since it can stick to the shoes and scratch your floors.
Types Of Decomposed Granite To Consider
If you’ve set your mind on a decomposed granite patio, you also need to take into account the type you will be choosing. More than just a variety of particle sizes and colors, there are also three major forms that decomposed granite comes in.
Natural (or loose) decomposed granite is when it is pure granite in its natural form and free from other additives.
Some of the characteristics of natural & loose DG you can take note of are the following:
• Least expensive decomposed granite option
• Ideal for garden beds (Used as a mulch material to be spread on the garden beds)
• Holds up better than other mulch materials and lasts longer
• Does not attract pests
• Keeps plants warm in winter
• Provides better drainage
The major downside with natural/loose DG is the fact that since it doesn’t have any stabilizer, it can get messy and muddy on rainy days. Installing them in high-traffic areas is not recommended.
Stabilized DG is decomposed granite embedded with stabilizers to make it a better quality material. The blend showcases the following features:
• Ideal for outdoor patios, driveways, and walkable pathways
• Less susceptible to weathering and erosion
• Low-level requirements
• Long lifespan
• Natural look compared to concrete and asphalt
Resin-coated DG refers to the decomposed granite that is blended with resin. Here are some of the characteristics that this blend offers:
• Most expensive type of DG
• Features a similar surface to that of asphalt
• Strongest and most durable DG option
• Less permeability
• Ideal for high-traffic areas like driveways and other similar outdoor areas

How To Build A Crushed Granite Backyard Patio
If you’re set on building your own decomposed granite patio, here are simple steps you can follow as your guide.
Step 1 – Planning and Designing: The first step before digging in your front yard is planning your design. Decide what type of patio you want to have, whether you’ll be using pavers, flagstones, or other materials, and how big you want your patio size to be. Draw the design and include the dimensions of the patio.
After you have created the layout for your backyard patio using the help of a landscape design software you are ready to buy materials and get started.architect or
Regarding the DG layout, you can install these materials next to walls, borders, and fences if you use them with a retaining or edging material that will keep the granite together.
Step 2 – Marking the Site: Go to your yard with strings, stakes, and spray paint, and mark the area where you will build your patio. Consider all the factors within that area, from elevations to weeds.
Step 3 – Digging the Area: Get your shovel or whatever digging tool you have and start excavating in the marked area. In general, dig 8 to 12 inches in the area where you want to build your patio.
The depth you will dig will depend on three factors: the soil type in the area, the kind of edging you will use, and if you want the top of your patio to be level with the soil around it. For most soils, you need a thick layer of decomposed granite if you’re going for a long-term DG path, driveway, or sitting area. In general, prepare at least 4 inches for your compacted DG.
For the edging, you will need to dig deeper if you use pavers compared to when using a redwood bender board. And finally, make sure to take into account 3 to 4 inches for mulch if you want to level the patio with the surrounding soil.
Step 4 – Install the Edging: One of the most common edgings used is redwood bender board, but you can also use boulders, pavers, and even steel edging, depending on your preference. The installation of your edging will depend on what it is, so make sure to explore it once you’ve made your choice.
Step 5 – Install the Decomposed Granite: Installing the DG is the easiest part of the process since you only need to dump it on the dug area and spread it over layer by layer. You can use tools to make sure that the DG is compact, like lifts and plate compactors.
You can put 1.5 to 2 inches of DG at a time in the lifts to be successful in having a full thickness. And make sure that the layers are even and smooth when you spread them out one layer at a time. Lastly, once you’re sure that your DG is compact, leveled, and smooth, lightly sweep a brown or leaf right on top of it for a natural and loose look.
Granite Pebbles Cost
Building a decomposed granite patio will set you back $40 to $60 per cubic yard for its raw product materials alone. If you choose a resin-coated DG material though, this cost will be higher since the material has a surface like asphalt.
Hiring a professional to install it for you will be an additional cost that can go around $4 to $6 per square foot. So, if you want to save money, building your DG patio yourself (and with the help of your friends) will be a better idea.

Pulverized Granite Problems
There are two notable problems you will come across when dealing with decomposed granite types of patios. First, if you happen to choose natural or loose DG, your surfaces will tend to erode and get muddy when wet.
The DG will stick to your shoes and scratch your floors when you enter your home with it. The solution is to give it a bit of a distance from your home and have a doormat ready just to be sure.
Second, if you choose a resin-coated DG patio, it is not permeable and tends to have drainage issues. This can affect nearby landscaping and soil health.
How Do You Keep DG In Place?

1. Make sure you dig deep enough to accommodate your DG
