How Much Decomposed Granite Do I Need? Calculator

FAQs

How do you calculate how much decomposed granite you need?

To calculate the amount of decomposed granite needed, follow these steps:

1. Measure the length and width of the area you want to cover in feet.
2. Multiply the length by the width to get the square footage.
3. Determine the desired thickness of the decomposed granite in inches.
4. Convert the thickness to feet by dividing by 12 (since there are 12 inches in a foot).
5. Multiply the square footage by the thickness in feet to get the cubic feet needed.
6. To estimate the tons required, divide the cubic feet by 27 (since there are 27 cubic feet in a cubic yard).

How much does 1 ton of granite cover?

1 ton of decomposed granite typically covers approximately 100 square feet at a depth of 2-3 inches.

How much area will 1 yard of decomposed granite cover?

One cubic yard of decomposed granite can cover about 100 square feet at a depth of 2-3 inches.

Does decomposed granite need to be compacted?

Yes, decomposed granite should be compacted to create a stable surface. This helps prevent erosion, improves durability, and ensures proper drainage.

Can you put decomposed granite over dirt?

Yes, you can put decomposed granite over bare soil or dirt. However, it’s important to prepare the area properly by removing any weeds, debris, and uneven surfaces before laying the decomposed granite. Compacting the decomposed granite is also essential.

Does water go through decomposed granite?

The recommended thickness for decomposed granite ranges from 2 to 4 inches when used as a ground cover or pathway material. However, the exact thickness may vary based on your specific project and intended use.

What are the disadvantages of decomposed granite?

Disadvantages of decomposed granite include its tendency to erode over time, its relatively rough surface texture, and its limited load-bearing capacity compared to solid surfaces like concrete.

How do you stabilize decomposed granite?

You can stabilize decomposed granite by adding a stabilizing agent, such as a liquid stabilizer or crushed fines, and then compacting the material thoroughly. This helps bind the particles together and reduces erosion.

Do you need drainage under decomposed granite?

Proper drainage is essential when using decomposed granite. If the area doesn’t naturally drain well, consider adding a base layer of crushed gravel or installing a drainage system to prevent water from pooling.

What is the difference between decomposed and crushed granite?

Decomposed granite is natural granite rock that has weathered and broken down into smaller particles. Crushed granite, on the other hand, is mechanically crushed granite rock. Decomposed granite tends to have a more irregular shape, while crushed granite is often more uniform in size and shape.

How long does it take for granite to decompose?

The process of granite decomposition is geological and occurs over millions of years due to weathering, erosion, and other natural forces.

How do you keep weeds from growing in decomposed granite?

To prevent weeds from growing in decomposed granite, you can use weed barrier fabric or apply a pre-emergent weed control product. Regularly maintaining the area by removing any weeds that do sprout is also important.

Is decomposed granite good for dogs?

Decomposed granite can be suitable for dogs as a ground cover in their outdoor play areas. It provides good drainage and is relatively easy to clean. However, some dogs may find the texture uncomfortable to walk on, so it’s essential to monitor your dog’s comfort and paw health.

Is breeze the same as decomposed granite?

“Breeze” is another term used for decomposed granite in some regions. They are often interchangeable names for the same material.

Does decomposed granite erode?

Yes, over time, decomposed granite can erode, especially in areas with heavy rainfall or foot traffic. Proper installation, compaction, and maintenance can help mitigate erosion.

Does decomposed granite have clay in it?

Decomposed granite can contain traces of clay, but its composition primarily consists of weathered granite rock particles.

What color is decomposed granite?

The color of decomposed granite can vary, but it is typically earthy in tone, ranging from gray and beige to reddish-brown, depending on the specific source of the granite.
