For a firmer decomposed granite pathway and easier installation, buy DG that has a stabilizer pre-mixed in. The instructions below are based on this type of DG. If stabilized DG isn’t available, you can purchase a soil stabilizer like Marloc-SS and follow the instructions on how to apply it to your pathway.
Does decomposed granite get hard?
Once compacted, a patio or walkway covered with lose DG will be fairly hard. However, loose DG is easily affected by erosion and will need to be filled in often.
How long does it take for decomposed granite to harden?
Allow 3 to 4 days for the Decomposed Granite to completely dry out. Maintenance and Repairs. 1. Loose aggregate will appear on the surface as time passes.
Can you add cement to decomposed granite?
Lastly, stabilized DG can be accomplished by simply mixing in Portland cement, mortar or another type of concrete material. While this is not advised for commercial application, the average homeowner with a few bags of concrete laying around may be able to stabilize their DG without much added cost.
What is the stabilizer in decomposed granite?
Stabilized DG is comprised of a stabilizer combined with the granite aggregates. This provides the decomposed granite with varying levels of permanence, depending on the stabilizer used. Unfortunately, not all stabilizers are permeable and some may allow environmentally-harmful materials to leach into the groundwater.
What is the difference between crushed and decomposed granite?
Crushed stone is closely related to decomposed granite (DG), but these rocks are not crushed as finely as DG. Both are popular for contemporary landscapes, but crushed stone offers a crisper look than DG. Pros: Crushed stone can be poured and compacted in any shape, providing design flexibility.
How do you maintain DG?
Apply DG in 1.5-inch layers, water down (don’t flood it) and tamp or use a heavy roller to compress the DG. Wait eight hours between layers to let the DG settle. Repeat the above steps for each subsequent layer. When properly installed, the DG surface will be rock hard, stable, dust-free and will allow water to drain.
How thick should DG be?
Some soils require a thicker layer of DG to hold up long term. With any soil, we recommend having at least 4” of compacted DG for your patio. But especially sandy soils, for instance, may require a thicker layer, or even a sub-base to stand the test of time.
What is the difference between fines and stabilized decomposed granite?
Decomposed Granite or DG is a natural byproduct of the weathering and erosion of solid granite rocks. DG is a combination of small granite pieces (⅜ inch or smaller) and fine granite, which can resemble sand. It is like gravel, but finer and more stable.
Does decomposed granite absorb water?
Water evaporates slower in surfaces covered with inorganic mulch like DG, which can help in water conservation. Since decomposed granite reduces water runoff, it also helps water to penetrate the soil more efficiently.
How do you install decomposed granite with stabilizer?
How to Install Decomposed Granite (DG) Step by Step.
How permeable is decomposed granite?
Compacted decomposed granite is a permeable material. Permeable surfaces lend themselves to aiding the soil and returning water to the water table. Permeable surfaces are also beneficial in that they won’t collect water and develop standing pools, which could lead to pests or other detrimental side effects.
How do you repair cracked decomposed granite?
The onsite aggregate/decomposed granite should be sieved to 1/8” minus material for better application and in-fill of cracks. Materials should be mixed as per ratio described above. Broom or fill the crack, moisten, compact (with rubber mallet or hand compaction plate) and “feather” material into the final finish.
How do you pack crushed granite?
A handheld tamper consists of a flat, heavy metal plate with a long rod or handle. Holding the end of the rod, bash the metal plate straight down against the granite repeatedly. You’ll add more granite as it compacts to keep the excavated area full. When the granite feels hard and firm, the job is done.
How long does DG stabilizer take to dry?
30 to 60 minutes but you should always stay off the surface for 24 hours after you apply.
Can dogs dig through decomposed granite?
Keeping pets and humans happy
In areas of high dog traffic, replace the grass with a more durable surface, like pea gravel or decomposed granite. These materials are safe for your dog to run on but won’t wear out.
Can DG be used on a slope?
With decomposed granite pathways, slope and crowning are the most beneficial methods of diverting water.
How do you make gravel hard?
brushing CHEAP concrete onto a gravel driveway (adding strength …
Is decomposed granite the same as 1/4 minus?
This is a similar material to ¼” minus, but is formed from weathered granite. It has a similar structure of small stones and finer particles, making it a good pathway gravel.
Can plants grow in decomposed granite?
Decomposed granite is natural, which means none of your plants are harmed when you use it. That’s what makes it the perfect material for garden beds. Plus, it provides better drainage than other bed substances, which means your plants will thrive.
How do you keep DG from washing away?
Decomposed granite and wood chips might wash away. The solution: Place barrier material such as rolled straw wattle, sandbags or cement edgers to redirect the flow to an established drainage path or into an open bed. Use a broom to brush off as much ponding water as possible.
How do you remove moss from decomposed granite?
How to Kill Moss on Decomposed Granite
- Cover nearby perennials, grass or shrubs with newspaper.
- Combine 1 pint of 62-percent zinc chloride with 3 gallons of water.
- Apply the zinc chloride to the affected area.
- Reapply as needed at seven- to 10-day intervals.
Is decomposed granite good for wet areas?
Decomposed granite can also be used to replace the lawn. The best part about it is that it’s still permeable, so rainwater will be able to get through into the soil beneath without running off and collecting near your home.
How much is a ton of DG?
The cost for a ton of decomposed granite is between $10 and $16, assuming the gravel has an average size of ½ inch. A cubic yard of ½-inch decomposed granite weighs about three tons, although this weight will decrease as the size of the gravel increases.
How many yards of DG do I need?
How much decomposed granite do you need? Multiply the length of the area to be covered, in feet, by the width, in feet, which gives you the area’s square feet. Then multiply the square feet by 0.25 feet (representing a minimum depth of 3 inches, converted to feet), which gives you cubic feet.
How do you clean decomposed granite?

Does DG absorb water?
DG is also an environmental way to go: it helps absorb rain water and irrigation, filters pollutants and solids from water, and is high in trace minerals.
