When to Use Decomposed Granite

A Decomposed Granite Drive

When to use decomposed granite

If you’ve chosen decomposed granite for a drive or garden path, you’ve made a really good choice. Not only is the material durable and inexpensive, it drains well and reduces dust. You also add more when it weathers or erodes. It’s also a versatile material. Along with drives and paths, it can be used for other landscaping projects such as xeriscape or as a transitional space between your garden and wilderness.

How much decomposed granite do I need?

If you want to figure out how much decomposed granite you need for your drive or another landscaping project, you’re going to have to figure out square footage. You do that by multiplying the area’s length by the width in feet. Because the granite is often sold by the cubic yard, you can take a couple of additional steps. First, take the square footage and multiply by 0.25 to get the cubic footage. Second, you divide the cubic feet by 27 for the cubic yardage.

Can you drive on decomposed granite?

There are several types of decomposed granite: loose, stabilized, and decomposed with resin. While any of these will work for a drive and can be driven on, typically the decomposed granite with resin is usually the best for drives. Though usually more expensive, it’s also more durable for high traffic areas. It also doesn’t erode and can’t be tracked away. At the same time, it doesn’t drain well and doesn’t look as natural as other types of granite.

How long does decomposed granite last?

The lifespan of decomposed granite will vary depending on the type of granite used. Loose granite will have to be replaced fairly frequently because it erodes quickly. On the other hand, when stabilizers are mixed in with the decomposed granite—or DG in the trade—it creates a harder surface that erodes much more slowly. Stabilized DG lasts about seven to 10 years. The most durable DG is DG with resin, which, as implied, has resin added to it. In some instances, this type of granite is comparable to asphalt and has a much harder surface than the other types of DG. It tends to last anywhere from 10 to 14 years.

Does decomposed granite harden?

The type of DG used will determine hardness. There are no additives in loose DG, so it is less hard than stabilized DG or DG with resin. If loose DG is compacted, however, it hardens. Stabilized DG hardens even more than loose DG and is less susceptible than loose granite to erosion. DG with resin is the hardest type of granite, is comparable to asphalt, and does not erode.

Is decomposed granite permeable?

When decomposed granite, or DG, is compacted, it will become permeable. This means it will allow more water to pass through it, which will aid your soil and return water to the water table. Compacting the DG also makes it less susceptible to erosion. Permeability also benefits your drive and landscaping because water won’t collect or create standing pools. This can eliminate problems with pests or other issues that can damage the drive.

Does decomposed granite need to be compacted?

Compacting loose decomposed granite will make the granite more permeable, which will benefit your soil. It will also make it less susceptible to erosion, which will stabilize the material and make it last longer. Moreover, compacting it will prevent loose stones from being tracked into your home. These loose stones can scrape and scuff hardwood and laminate flooring and damage your vehicle’s floorboards.

Do weeds grow through decomposed granite?

Once you’ve compacted loose decomposed granite, you’ll have little worry about weeds growing through it. Although weeds can grow through the material, they have a tough time of it because they typically have to push through about three to four inches of material. When they do push through, you can usually get rid of them pretty easily with a garden hoe or a herbicide.

What is similar to decomposed granite?

Decomposed granite isn’t the only aggregate available for paving and landscaping. Other types of materials include:

  • Pea gravel: Although it is easy to walk on and controls erosion well, it’s also less stable than other materials and requires edging materials to contain it.
  • River rocks: Though aesthetically pleasing, these smooth rocks are primarily used for garden paths and as edging for gardens.
  • Crushed stone: Similar to DG but not as finely crushed. It’s not good for play areas because of sharp edges. It’s suitable for drives but has to be replenished frequently.
