How Much Does Decomposed Granite Cost Per Yard?
Decomposed granite (DG) is a popular landscaping and hardscape material used for pathways, patios, driveways, garden areas, and outdoor living spaces. It provides a natural stone appearance while offering a more affordable alternative to concrete, pavers, and other hardscape materials.
One of the most common questions homeowners and contractors ask is: how much does decomposed granite cost per yard?
The average cost of decomposed granite is typically around $30 to $70 per cubic yard for the material alone, depending on the type, location, color, supplier, and whether the DG is stabilized. With delivery and installation included, the total project cost can increase significantly.
The final price depends on more than just the cost of the material. Factors such as site preparation, delivery distance, compaction requirements, and the type of decomposed granite selected all influence the overall investment.
What Is Decomposed Granite?
Decomposed granite, often called DG, is a natural material created when granite rock gradually breaks down into smaller particles over time.
Unlike large landscape rocks, decomposed granite consists of a mixture of:
- Small granite fragments
- Fine mineral particles
- Natural stone dust
This combination gives DG a unique texture that can be compacted into a firm surface while maintaining the appearance of natural stone.
It is commonly used for:
- Garden pathways
- Walking trails
- Patios
- Courtyards
- Driveways
- Landscape areas
- Decorative ground cover
Products such as decomposed granite are available in different grades depending on whether the project requires drainage, stability, or a more decorative finish.
Average Cost of Decomposed Granite Per Yard
The price of decomposed granite varies by region and product quality.
A general material cost range is:
Standard decomposed granite: $30–$50 per cubic yard
Stabilized decomposed granite: $40–$70+ per cubic yard
These prices are estimates and may vary based on local availability, transportation costs, and supplier pricing.
Standard DG contains natural fines that allow it to compact, making it suitable for many landscaping applications.
Stabilized DG includes a binding agent that helps the material stay in place, making it a better option for areas with higher foot traffic, slopes, or locations where erosion is a concern.
- Water flow speed
- Channel slope
- Drainage area
- Soil conditions
- Expected rainfall intensity
Factors That Affect Decomposed Granite Cost
Several factors determine the final price you pay for decomposed granite.
Type of Decomposed Granite
Not all DG products are the same.
Standard DG is typically the most affordable option and works well for:
- Low-traffic pathways
- Garden areas
- Decorative landscaping
Stabilized DG costs more because it includes additional material that improves strength and durability.
For areas such as patios or frequently used walkways, stabilized options may provide better long-term performance.
Color and Appearance
Decomposed granite is available in different natural colors depending on the source rock.
Common colors include:
- Gray
- Tan
- Gold
- Brown
- Red tones
Some decorative DG products cost more because they provide a specific appearance desired for landscape design projects.
Delivery Distance
Because decomposed granite is a bulk material, transportation can significantly affect the final cost.
A cubic yard of DG weighs approximately 2,000 to 3,000 pounds depending on moisture content and density, so delivery requires specialized equipment.
The farther the supplier must travel, the higher the delivery charge may be.
For bulk projects, choosing a local supplier can often reduce transportation costs.
Project Size
Larger projects usually have a lower cost per cubic yard because bulk orders are more efficient to deliver.
A small pathway project may require only a few yards, while a driveway or large landscape installation may require dozens of cubic yards.
Accurate measurement helps prevent ordering too much or too little material.
How Much Decomposed Granite Do You Need?
Decomposed granite is sold by volume, usually by the cubic yard.
To calculate how much DG you need, use:
Length × Width × Depth = Cubic Volume
For example:
A pathway that is 50 feet long, 4 feet wide, and 3 inches deep requires approximately 1.85 cubic yards of decomposed granite.
Most DG installations are placed at a depth of:
- 2–3 inches for decorative ground cover
- 3–4 inches for pathways
- 4–6 inches for heavier-use areas or driveways
The required depth depends on the intended use and the condition of the existing soil.
Is Stabilized Decomposed Granite Worth the Extra Cost?
For many projects, stabilized decomposed granite is worth considering.
Regular DG can shift over time, especially in areas exposed to:
- Heavy foot traffic
- Rainfall
- Sloped terrain
- Vehicle use
Stabilized DG contains a binding material that helps the particles lock together after installation.
It creates a firmer surface while maintaining the natural appearance of granite.
For patios, walkways, and frequently used outdoor spaces, stabilized DG often provides better value because it may require less maintenance over time.
Decomposed Granite Cost Compared With Other Landscaping Materials
Decomposed granite is often chosen because it provides a balance between cost, appearance, and performance.
Compared with concrete:
- DG is generally less expensive
- Installation is usually simpler
- It provides a more natural appearance
Compared with gravel:
- DG creates a smoother walking surface
- It compacts more firmly
- It produces less loose material movement
Compared with pavers:
- DG has a much lower material and installation cost
- However, pavers may provide a more permanent finished surface
The best choice depends on the project’s purpose, design preferences, and maintenance expectations.
Does Decomposed Granite Require Maintenance?
Yes, although maintenance requirements are usually low.
Over time, decomposed granite surfaces may develop:
- Low spots
- Minor erosion
- Loose areas
Maintenance may include:
- Adding additional DG material
- Minor erosion
- Loose areas
Proper installation plays a major role in reducing future maintenance.
A properly prepared base, correct depth, and adequate compaction help DG remain stable.
Is Decomposed Granite Good for Driveways?
Decomposed granite can be used for driveways, but the application requires careful preparation.
Standard DG may not perform well under frequent vehicle traffic because it can shift and create ruts.
For driveways, many contractors recommend:
- A properly compacted base layer
- Adequate DG depth
- Stabilized decomposed granite when appropriate
Materials such as stabilized decomposed granite are specifically designed to improve durability and reduce movement.
For heavy-use driveways, other materials such as crushed rock or road base may provide stronger structural support.
Common Mistakes When Buying Decomposed Granite
One common mistake is buying DG based only on the lowest price per yard.
Cheaper material may not always be suitable for the intended application.
Another mistake is failing to calculate the correct quantity. Ordering too little can delay a project, while ordering too much increases waste.
Some homeowners also skip proper base preparation, which can lead to premature settling.
The quality of the installation is just as important as the quality of the material.
Final Thoughts
So, how much does decomposed granite cost per yard?
The average cost is typically $30 to $70 per cubic yard, depending on the type of DG, location, color, supplier, and whether it is stabilized.
Decomposed granite remains one of the most versatile landscaping materials because it offers a natural stone appearance, good compaction, and a relatively affordable price compared with many hardscape alternatives.
For the best results, choose the right type of DG for your project, calculate the correct amount needed, and ensure proper installation with adequate preparation and compaction.
