What is Decomposed Granite?
Decomposed granite is a type of granite rock that has weathered to the point of breaking into smaller pieces. These pieces are often smaller than a quarter of an inch and resemble sand. It’s available in a range of colors from gold to brown, red to green, making it a versatile choice for many landscapes.
Why Choose Decomposed Granite for Your Driveway?
- Natural Aesthetic: Its earthy tones blend seamlessly into a natural landscape.
- Cost-Effective: At $0.30 to $0.70 per square foot, it’s cheaper than asphalt, concrete, and pavers.
- Environmentally Friendly: Requires minimal processing and allows rainwater to percolate back into the ground.
Pros of Decomposed Granite Driveways
-
Great Drainage
- Decomposed granite is highly permeable, making it an excellent choice for areas prone to heavy rainfall. This feature helps prevent flooding and allows water to drain efficiently.
- Example: A homeowner in a flood-prone area found that their decomposed granite driveway significantly reduced water pooling after storms.
-
Affordability
- One of the most budget-friendly options available, it leaves more room in the budget for landscaping or other home improvements.
- Example: Compared to gravel driveways, which can cost $1.25 to $1.80 per square foot, decomposed granite is a steal.
-
Aesthetic Appeal
- Offers a natural appearance that blends well with gardens and other landscaping features.
- Available in various hues, it can complement any home’s exterior.
-
Environmentally Friendly
- Minimal processing and chemical use make it an eco-friendly choice.
- Its permeability supports groundwater recharge, reducing runoff and erosion.
Cons of Decomposed Granite Driveways
-
Requires Proper Stabilization
- Without proper stabilization, the material can become loose, leading to issues such as dust and erosion.
- Tip: Consider using a stabilizer or binding agent to solidify the surface.
-
Loose Material
- Can migrate over time, requiring maintenance to keep the driveway intact.
- Suggestion: Regular raking can help maintain a smooth surface.
-
Not Ideal for All Climates
- In regions with heavy snowfall, decomposed granite may not be the best choice as it can be difficult to plow without displacing the material.
-
Shorter Lifespan
- Typically lasts 7 to 10 years before needing a refresh. However, it’s easy to replenish by adding more material.
