Irish Knights Green Decomposed Granite

1. What is decomposed granite and how is it different from regular gravel?

Decomposed granite (DG) is a natural material formed from the weathering of granite rock. It breaks down into fine particles that resemble sand but are slightly coarser. Unlike regular gravel, DG creates a smoother, more compact surface that’s ideal for pathways, patios, and garden areas.

2. How much does decomposed granite cost per ton or per yard?

The price of decomposed granite typically ranges from $50 to $75 per ton or $35 to $55 per cubic yard, depending on the color, quality, and delivery distance. Stabilized or resin-bound DG costs more due to the added binding agents.

3. What are the pros and cons of using decomposed granite for landscaping?

Pros: Natural appearance, good drainage, low maintenance, and eco-friendly.

Cons: Can be dusty in dry climates, may shift over time if not compacted, and needs occasional top-up.

4. How do you install decomposed granite for driveways or pathways?

To install DG, remove the topsoil, level the surface, and add a 2–3 inch base layer of crushed stone for stability. Then spread decomposed granite evenly, wet it, and compact it firmly using a plate compactor. For driveways or high-traffic areas, stabilized DG is recommended.

5. Does decomposed granite need to be compacted or sealed?

Yes. Compaction helps DG bind together and prevents erosion or shifting. Sealing is optional but recommended for areas exposed to rain or heavy use — it helps harden the surface and reduce dust.

6. What is stabilized decomposed granite, and when should I use it?

Stabilized DG is decomposed granite mixed with a binder that helps it stay firm and resistant to erosion. It’s ideal for driveways, patios, and high-traffic walkways where durability and minimal maintenance are important.

7. How long does decomposed granite last before it needs maintenance?

When properly installed and compacted, decomposed granite can last 7–10 years or longer. Light maintenance such as re-compacting and adding a thin top layer every few years helps maintain its appearance and firmness.

8. Can decomposed granite be used for bocce ball courts or patios?

Yes, decomposed granite is one of the most popular materials for bocce ball courts because it provides a smooth, firm, and permeable surface. It’s also excellent for patios due to its natural look and good drainage.

9. Is decomposed granite environmentally friendly and permeable?

Absolutely. DG is a natural and permeable material, allowing water to pass through easily and reducing runoff. It’s an eco-friendly alternative to concrete and asphalt, making it great for sustainable landscaping.

10. What color options are available for decomposed granite?

Decomposed granite comes in a variety of colors, including gold, tan, brown, gray, black, red, and rose. The color depends on the original granite source and adds a beautiful, natural tone to any landscape design.
