How Much Does A Yard Of Decomposed Granite Weigh

How Much Does a Yard of Decomposed Granite Weigh?

Decomposed granite (DG), a popular landscaping material, is prized for its versatility, permeability, and attractive appearance. But before you embark on your next landscaping project, understanding its weight is crucial for planning transportation, installation, and overall project cost. So, how much does a cubic yard of decomposed granite weigh?

Understanding the Variables Affecting Weight

Unlike some materials with consistent density, the weight of decomposed granite varies. Several factors influence its overall mass:

1. Particle Size:

The size of the DG particles directly impacts density. Finely graded DG will be denser and heavier than a coarser grade with larger particles and more air pockets. Think of it like packing sand versus pebbles – the sand will weigh more in the same volume.

2. Moisture Content:

Wet DG is significantly heavier than dry DG. Water adds considerable weight, and the extent of this increase depends on the level of saturation. This is a crucial factor to consider, especially if you're buying DG delivered during a rainy season.

3. Mineral Composition:

The specific minerals comprising the decomposed granite can slightly affect the density. While the variation is typically minor compared to particle size and moisture, slight differences can exist between quarries and sources.

Estimating the Weight: A Practical Approach

While a precise weight is impossible to state without knowing the specific variables mentioned above, we can offer a reasonable estimate. A cubic yard of dry, well-compacted decomposed granite typically weighs between 2,400 and 2,800 pounds (1.2 to 1.4 tons).

However, remember this is an average. It's best to contact your supplier for a more accurate weight estimate. They'll have specifics on the DG grade they're providing, and can account for moisture content at the time of delivery.

Why Knowing the Weight Matters

Accurately estimating the weight of DG is vital for several reasons:

1. Transportation Costs:

Trucking companies charge by weight, not volume. An accurate weight estimate is essential for budgeting transportation costs. Underestimating the weight can lead to unexpected expenses.

2. Structural Considerations:

If you're using DG for a retaining wall or other load-bearing application, understanding the weight is crucial for structural integrity. Too much weight on an inadequately designed structure can lead to failure.

3. Equipment Selection:

Using appropriate equipment for handling and spreading the DG is crucial for efficiency and safety. The weight will help you determine whether you need a wheelbarrow, a small dump truck, or a larger piece of heavy equipment.

Conclusion: Planning is Key

Knowing the approximate weight of a cubic yard of decomposed granite is a valuable tool in successful landscaping. While the exact weight will fluctuate, understanding the key variables and obtaining information from your supplier will empower you to plan effectively and avoid unexpected complications. Remember to factor in the potential for added weight from moisture, and always err on the side of caution when making estimations.
