Need to calculate how much natural decomposed granite you need for your DFW project? For every 100 square feet at a 2-inch depth, you'll need approximately 1 ton of decomposed granite, while a 3-inch depth requires about 1.5 tons. Our calculator and guide below will help you determine the exact tonnage and understand the factors influencing your project's total cost.
Why Choose Natural Decomposed Granite for Your DFW Project?
Natural decomposed granite (DG) is a versatile and attractive material, making it a popular choice for various landscaping and hardscaping projects across DFW, TX. From pathways and patios to driveways and garden beds, its natural aesthetic, durability, and excellent drainage properties make it an ideal selection. Unlike crushed gravel, DG features finer particles mixed with larger aggregates, which compact beautifully to create a firm, permeable surface that still allows for water penetration, reducing runoff.
This article will guide you through calculating the precise amount of natural decomposed granite needed for your project, explain installation considerations, and detail delivery options available from Kaufman Sand & Gravel. Whether you're a seasoned contractor or tackling a DIY project, accurate material estimation is key to staying on budget and avoiding delays.
Understanding Your Decomposed Granite Project: Common Uses
Natural decomposed granite offers a unique blend of functionality and aesthetics. Here are some of its most common applications in DFW:
- Pathways and Walkways: Create inviting, natural-looking paths that blend seamlessly with your landscape. DG offers a stable, yet permeable surface.
- Patios and Outdoor Living Areas: A decomposed granite patio provides a rustic, charming feel that's cooler underfoot than traditional concrete or pavers.
- Driveways (Light Traffic): For residential driveways or areas with lighter vehicle traffic, DG can be a cost-effective and attractive alternative to asphalt or concrete.
- Bocce Ball Courts or Pet Runs: Its compactable nature makes it ideal for recreational surfaces that require a firm, level base.
- Garden Bed Mulch: While less common than wood mulches, coarser DG can be used as an inorganic mulch layer to suppress weeds and retain soil moisture in arid garden designs.
Decomposed Granite Installation Sequence: Path & Patio
Proper installation is crucial for the longevity and performance of your decomposed granite surface. Here's a typical sequence for a path or patio:
- Site Preparation: Clear the area of any vegetation, rocks, and debris. Dig down to the desired depth, accounting for your edging, base layer, and DG layer. Ensure proper drainage by creating a slight slope away from structures (typically 1/4 inch per foot).
- Edging Installation: Install a sturdy border or edging material (e.g., steel, concrete, wood, or stone). This is critical to contain the natural decomposed granite and prevent it from spreading over time. Ensure the top of the edging is flush with or slightly above your planned finished DG surface.
- Base Layer (Optional but Recommended): For high-traffic areas, or areas prone to moisture, a compacted aggregate base (like crushed limestone or gravel) is highly recommended. Spread a 2-4 inch layer of base material, moisten it, and compact it thoroughly with a plate compactor. This provides a stable, well-draining foundation. You can find suitable gravel options on our gravel delivery page.
- Decomposed Granite Layer: Spread your natural decomposed granite evenly over the base. For pathways and patios, a finished compacted depth of 2-3 inches is common.
- Moisten and Compact: Lightly mist the DG layer with water. This helps the finer particles settle. Then, compact the entire surface thoroughly with a plate compactor. Repeat this process – misting and compacting – until the surface is firm and level. You may need to add more DG if it compacts significantly below your desired height.
- Final Touches: Sweep off any loose material. For an even firmer surface, some contractors apply a polymeric stabilizer, but natural compaction often suffices.
How Much Natural Decomposed Granite Do You Need? Tonnage Calculator
Accurately calculating your material needs is crucial for a smooth project. Use this guide to determine how much natural decomposed granite to order.
Step 1: Measure Your Project Area Measure the length and width of your project area in feet.
- Square Footage (sq ft) = Length (ft) x Width (ft)
Step 2: Determine Your Desired Depth Most decomposed granite paths and patios are installed at a compacted depth of 2-4 inches.
- For light traffic paths, 2 inches compacted is often sufficient.
- For patios or moderate traffic areas, 3 inches compacted is recommended.
- For driveways or heavy-use areas, 4 inches compacted may be necessary, often over a substantial base layer.
Step 3: Calculate Cubic Feet Convert your desired depth from inches to feet by dividing by 12.
- Depth (ft) = Depth (inches) / 12
- Cubic Feet (cu ft) = Square Footage (sq ft) x Depth (ft)
Step 4: Convert Cubic Feet to Tons Decomposed granite typically weighs about 2,700-3,000 pounds per cubic yard, or roughly 1.35-1.5 tons per cubic yard. For easier calculation, we'll use a common conversion: 1 ton covers approximately 80-100 square feet at 2 inches deep.
A more precise calculation:
- 1 Cubic Yard ≈ 27 Cubic Feet
- 1 Ton ≈ 20 Cubic Feet (average for DG)
Therefore:
- Tons Needed = Cubic Feet (cu ft) / 20
Example Calculation: Let's say you're building a patio that is 15 feet long by 10 feet wide, and you want a compacted depth of 3 inches.
- Square Footage: 15 ft x 10 ft = 150 sq ft
- Depth in Feet: 3 inches / 12 = 0.25 ft
- Cubic Feet: 150 sq ft x 0.25 ft = 37.5 cu ft
- Tons Needed: 37.5 cu ft / 20 = 1.875 tons
Recommendation: Always round up to the nearest whole or half ton to account for compaction, waste, and minor variations. In this example, you'd likely order 2 tons of natural decomposed granite.
Decomposed Granite Tonnage & Coverage Chart
This table provides quick estimates for common depths. Remember that actual coverage can vary slightly based on the specific material, compaction effort, and subgrade.
| Desired Compacted Depth | Coverage per Ton | Tons per 100 sq ft |
|---|---|---|
| 1 inch | 200 sq ft | 0.5 tons |
| 2 inches | 100 sq ft | 1 ton |
| 3 inches | 67 sq ft | 1.5 tons |
| 4 inches | 50 sq ft | 2 tons |
Pro Tip: It's always better to over-order slightly than to run short, as additional small deliveries can incur extra costs. Consider adding an extra 5-10% to your calculation.

Frequently Asked Questions (FAQ)
Q: What is the difference between decomposed granite and gravel? A: Decomposed granite (DG) is made of fine particles mixed with larger aggregates, giving it a natural, organic look. It compacts very firmly, almost like concrete, but remains permeable. Gravel typically consists of larger, more uniformly sized crushed stones that do not compact as tightly and tend to shift more.
Q: Does decomposed granite drain well? A: Yes, natural decomposed granite has excellent drainage properties. When properly installed and compacted, it creates a firm surface that allows water to percolate through, reducing runoff and puddling. This makes it a great choice for areas where water management is a concern.
Q: How much clearance do I need for a bulk material delivery? A: Our delivery trucks require adequate space to maneuver and dump materials safely. Typically, we need at least 10-12 feet of width and 15-20 feet of overhead clearance (free of power lines, tree branches, etc.) at the drop-off location. Please discuss any access concerns when placing your order.
