What is Decomposed Granite?
Decomposed Granite is a natural material formed from the gradual weathering and breakdown of solid granite rock. Over time, exposure to wind, water, and temperature changes causes granite to crumble into smaller particles. What you’re left with is a mixture of tiny stone, silt, and clay that is both functional and attractive.
There are three main types of Decomposed Granite:
1. Natural Decomposed Granite
This is the raw form of DG, with no added binders. It’s often used in low-traffic areas like garden paths or ground cover. Natural DG is appreciated for its affordability and rustic look.
2. Stabilized Decomposed Granite
This version has a stabilizing agent (like organic or polymer binders) mixed in. It creates a more solid, compacted surface, making it ideal for walkways, driveways, and patios. It holds up better in rainy climates compared to loose DG.
3. Resin-Bound Decomposed Granite
This premium type is combined with a resin to form a smooth, durable, and nearly impermeable surface. It’s often used for public parks or high-end landscaping where stability and appearance matter most.
What makes Decomposed Granite unique is its versatility. It’s available in different colors, textures, and grades, allowing for customized landscaping. Plus, it’s environmentally friendly, naturally draining, and blends seamlessly into natural surroundings.
Whether you’re planning a path through your backyard or creating a large public space, understanding the different forms of Decomposed Granite is key to selecting the right type for your needs.

Choosing the right type of Decomposed Granite ensures you get the look, function, and lifespan that fit your outdoor project.
Decomposed Granite vs. Gravel vs. Crushed Stone
When it comes to landscaping, people often confuse Decomposed Granite, gravel, and crushed stone. While they may appear similar, each has distinct characteristics, making them better suited for different applications.
Decomposed Granite
Decomposed Granite is granite that has weathered over time into fine particles, ranging from sand-like texture to small pebbles. It compacts well, provides excellent drainage, and is aesthetically pleasing. DG is available in multiple colors and can be used as loose, stabilized, or resin-bound depending on the project.
Gravel
Gravel consists of larger, irregular rock fragments typically rounded from natural weathering or mechanical processing. It doesn’t compact as tightly as DG and is often used for driveways, drainage, and base material. Gravel can be uncomfortable for walking and requires edging to stay in place.
Crushed Stone
Crushed stone is produced by mechanically breaking down rock, usually limestone or granite, into angular pieces. It offers a strong base for construction projects but is less visually appealing than DG. It is commonly used for road bases, concrete mixes, and foundations.
Key Differences
| Feature | Decomposed Granite | Gravel | Crushed Stone |
|---|---|---|---|
| Texture | Fine and sand-like | Coarse and rounded | Angular and sharp |
| Appearance | Natural and decorative | Rugged and casual | Industrial |
| Compaction | High | Low | Medium |
| Comfort for walking | High | Low | Medium |
DecomposedGranite is your best choice for decorative landscaping and paths, while gravel and crushed stone serve better for structural and drainage needs.
How to Install Decomposed Granite Properly
Proper installation of Decomposed Granite ensures a stable, long-lasting surface. Whether you’re building a path, patio, or driveway, following a structured process is crucial for best results.
Step 1: Site Preparation
Begin by marking the area and removing any grass, roots, or debris. Dig down to a depth of 4–6 inches depending on the traffic level. Create a slight slope for water drainage, especially for patios and walkways.
Step 2: Laying the Base
Add 2–3 inches of crushed stone or gravel as the base layer. This improves drainage and provides stability. Compact this layer using a plate compactor to avoid settling over time.
Step 3: Weed Barrier (Optional)
Installing a weed barrier fabric can help prevent unwanted growth, though some prefer skipping it for better drainage. This step is optional but helpful in long-term maintenance.
Step 4: Add Decomposed Granite
Spread 1.5–2 inches of Decomposed Granite over the base. If using stabilized DG, make sure it’s pre-mixed with the stabilizer or use a spray-on binder afterward. Rake it evenly across the surface.
Step 5: Compaction
Use a plate compactor to compact the DG thoroughly. Apply water with a fine spray to help particles bond together. Repeat layering and compacting if needed until you reach the desired height.
Final Touches
Edge the area with metal, stone, or wood borders to keep the DG in place. Let the surface cure for 24–48 hours before heavy use.
Installing Decomposed-Granite correctly ensures durability, minimizes erosion, and keeps your surface beautiful for years.
