What is decomposed granite landscaping?
View all landscaping pictures. Decomposed granite, or DG, is made up of granite aggregates a 1/4" or smaller. Sometimes DG is so fine that it resembles sand. Decomposed granite is the least expensive way to pave a patio, walkway, or driveway. DG provides a natural, rustic look and is available in subtle hues of gray, tan and brown.
Can decomposed granite be mixed with resin before being laid down?
As far as I know, any resins or stabilizers which are in decomposed granite are added prior to it being laid down. It is ordered that way or sometimes a contractor can mix it himself prior to installation. I am not familiar with any way to add these materials once the DG is down already.
What does decomposed granite look and feel like?
Decomposed granite looks and feels similar to gravel but has a finer texture. It is formed from natural weathering (where nature’s elements breaks down larger rocks and minerals to smaller particles) and erosion of solid granite. These processes turn it from something large, hard and tough into smaller pieces of weaker rocks.
What are the cons of decomposed granite?
CONSLoose DG will easily erode and become muddy when wet.DG with resin does not provide good drainage.May need to be refilled from time to time and matching up the exact color may be difficult (it's recommended to keep some of the original on hand)Loose DG can be tracked indoors and damage hardwood flooring.

Does decomposed granite need to be compacted?
Applying decomposed granite in thin layers, then moistening and compacting each layer, is very important. Otherwise, only the very top of your pathway is compacted and the pathway will become a sandbox once the upper crust cracks.
How thick should decomposed granite be?
Once the decomposed granite is level, use a hand roller compactor or hand tamper to finish the job. The compacted layer needs to be at least 4 to 6 inches thick to be structurally sound. Add additional layers until you achieve the right look and feel.

Does decomposed granite absorb water?
Water evaporates slower in surfaces covered with inorganic mulch like DG, which can help in water conservation. Since decomposed granite reduces water runoff, it also helps water to penetrate the soil more efficiently.
Does decomposed granite need to be compacted?
Applying decomposed granite in thin layers, then moistening and compacting each layer, is very important. Otherwise, only the very top of your pathway is compacted and the pathway will become a sandbox once the upper crust cracks.
Where Can You Find Decomposed Granite?
Crushed decomposed granite is produced by more than 100 quarries throughout various regions around the United States. Because of the varying levels of chemical composition around the U.S. and Canada, quarries in different regions will produce DG of different colors. In Kafka Granite’s home turf, for example, vibrant reds, browns, and golds are most prominent. Other regions may be known for their tans or greys.
What Is Decomposed Granite Used For?
In fact, DG is harder than marble, and its unique composition allows it to compact firmly for patios, ballparks, driveways, pathways and trail systems, and landscapes, or for more high-traffic applications such as roads, while maintaining drainage characteristics not found in most other hardscape surfaces.
How Is the Quality of Decomposed Granite Products Maintained?
A sieve analysis is used to guarantee that every shipment of product contains the right proportions of stone sizes . For instance, the specifications for one pathway mix might require that 80 percent of the stones in a mix be smaller than 3/16 inch, 65 percent be smaller than ⅛ inch, and so on.
How Can Decomposed Granite Contribute to Sustainable Efforts?
There are several ways in which decomposed granite can contribute to your LEED certification efforts. By earning points to be Leadership in Energy & Environmental Design certified, your project can reach varying levels of sustainability. Striving to build a green, eco-friendly project will benefit the environment for years to come.

Is stabilized decomposed granite more expensive than loose granite?
Stabilized Decomposed Granite - Stabilized DG has a stabilizer mixed in with the granite aggregates. Compared to loose DG, stabilized DG is more expensive, but it's still less money than pavers, decorative concrete and natural stone. Once spread and compacted, DG with a stabilizer will look similar to loose DG, with the top layer appearing loose and organic. However, stabilized decomposed granite will be less susceptible to erosion. As a result, it has a longer life span and requires less maintenance than loose DG. Many landscaping companies will deliver DG with a stabilizer already mixed in.
