Decomposed granite (DG) is a great choice for decorating patios and creating pathways, seating areas, and the like.
It is a rock that has been weather-beaten and can easily fragment into smaller fragments of weak rocks. It is often 3/8 inch or smaller in size.
This granite has a wide variety of applications that makes it popular in places like the Southwestern regions of the United States.
Even though it is a popularly adopted hardscaping material, it has a number of disadvantages, which is what this article is about. Read on to find out the most common disadvantages of decomposed granite.
Types of Decomposed Granite
The three major types of DG are outlined below.

Natural Loose DG
This is a naturally occurring DG that is not mixed with any additive. It is usually installed and compacted using a Vibraplate.
This enables the particles to fuse together and stay in place. They’re often used for seating areas, parks, and pathways with less traffic.
This is the least expensive type that’s often used by most people with a low budget. It gives a garden path a nice look and attractive appearance.
Stabilized DG is mixed with stabilizing agents that help to bind the particles together and keep them in place.
The particles become packed together and have a tough and hard appearance. This helps to reduce erosion and some other problems associated with the use of DG.
Even with the use of stabilizers, keep in mind that the major problems of erosion and damage caused by debris are not completely eliminated; they’re only reduced.
DG with Resin
This is the most expensive type and the most preferred for high-traffic areas. It involves mixing DG with resin to bind the particles together turning them into an asphalt-like material.
The surface becomes hard and the texture is altered. And the sandy appearance is eliminated.
Advantages (Pros) of Decomposed Granite
I know this article is supposed to focus on the disadvantages of DG. But I believe it doesn’t hurt to have a quick look at some of its advantages.
- It is easy to install
- It is available in a variety of colors
- DG is a good choice for xeriscaping
- It gives a natural appearance
- Loose DG is inexpensive
Disadvantages (Cons) of Decomposed Granite
The following are the major disadvantages of decomposed granite.
1. It gets muddy
Decomposed granite tends to get muddy during the winter when there is high rainfall.
DG is composed of granite fines and small pieces of granite; this combination has a high tendency of fusing together with the presence of water. This results in DG changing its form from loose to muddy.
This process doesn’t occur with gravels. It’s a problem that is specific to DG. It can, however, be reduced by the introduction of resins.
But this is quite expensive and can be a tough step when you need DG in large quantities for a large hardscaping project.
2. It has a tendency to grow weeds
Not only can it grow weeds, but it can also grow moss. Weeds and moss are a great challenge that you have to face with DG.
This will require you to frequently rake it to remove the unwanted visitors. When you use DG on your patio, you need to have in mind that it is not maintenance-free like having concrete on your walkway.
The presence of weeds and moss will alter the appearance of your environment and will keep the installed DG from looking as beautiful as you expect. You have to frequently rake it to avoid this.
This could be tiring if you have to do it alone.
3. It has a tendency to erode
Except when used with additives, DG has a very high tendency to erode.
And it tends to erode over time even when additives are used. It is made of rocks that have weathered and can easily fracture into smaller pieces.
This makes it susceptible to erosion, especially during the winter when the rainfall is high.
Erosion causes a reduction in quantity and changes the appearance of your walkway, patio, or environment in general.
This can happen in a short while or over time, depending on the type of DG in question. Natural DG without additives erodes quickly while DG with additives takes more time to erode.
4. It is more suitable in certain environments
DG is preferable and more suitable for use in areas with less rainfall. This is obviously due to its nature.
The particles have a tendency to become muddy and erode over time as a result of frequent rainfall.
Although DG is permeable and allows water to percolate and seep through to the ground, it retains water, which also has an effect on its features.
The retained water makes it muddy and messy. As a result, the environment may become uncomfortable and inconvenient for easy movement on foot.
5. It requires frequent refilling
You may need to refill your patio or walkway from time to time when you use DG. This is a result of possible erosions that may occur over time.
The problem of erosion is even more challenging when you have to refill with the same color of DG.
Getting the exact match is sometimes very difficult. It could be out of stock and may not be available for a long time due to several reasons.
One way of overcoming this is to prepare beforehand. Get some of the original available and have them around as a backup.

6. Debris may damage floors
This is a common occurrence, especially when you place DG near the entrance of your home.
The granite can be tracked in by anyone or even your pet. This can cause damage if you have hardwood flooring.
You may have to install a floor mat to avoid this damage. In this case, the debris will be trapped in the mat and you’ll have to sweep it off regularly.
This means more work in terms of maintenance in order to keep the environment clean.
7. DG with resin is expensive
Most of the disadvantages of DG can be minimized by mixing it with natural resin. But this is another problem on its own; it’s expensive.
Another problem associated with mixing DG with resin is that it becomes asphalt-like material.
The end result is more asphalt-like than DG-like, and this may become less desirable for the original purpose it’s needed for.
Where to Use DG
DG is a versatile material that has several uses. It can be used in areas with low traffic and is suitable for use in areas with high traffic. Some of the major places it can be used include:

Decomposed Granite Driveway Disaster
Decomposed granite can present challenges when used for driveways, especially in areas with heavy rainfall or poor drainage.
These conditions can contribute to the shifting and unevenness of the material, resulting in an unstable and bumpy surface.
Let’s delve deeper into these issues and discuss potential solutions.
Shifting and Unevenness
One of the primary concerns with DG driveways is the tendency of the material to shift.
This can occur due to water runoff, erosion, or the natural settling of the ground.
When decomposed granite moves, it creates an uneven surface that can be challenging to traverse, particularly for vehicles.
Proper installation and preparation are crucial to mitigate shifting and unevenness.
Before laying decomposed granite for a driveway, it’s important to excavate the area and ensure a stable base.
This typically involves removing the topsoil and compacting the subgrade to create a firm foundation.
Adding a layer of geotextile fabric between the subgrade and decomposed granite can further aid in stabilization by preventing the intermixing of materials.
Another factor that can contribute to a decomposed granite driveway disaster is poor drainage.
If the driveway doesn’t have an adequate slope or if the surrounding landscape lacks proper drainage systems, water can accumulate and seep into the surface of the DG.
This can lead to erosion, which washes away the fine particles and causes the driveway to become uneven and prone to potholes.
To address drainage issues, it’s essential to evaluate the slope of the driveway and ensure that water flows away from the surface.
Proper grading and the installation of drainage channels or French drains can help redirect water and prevent it from pooling on the driveway.
Incorporating a border or edging material along the sides of the driveway can also help contain the decomposed granite and prevent it from spreading or eroding.
Crushed Granite Walkway Pros and Cons
Crushed granite walkways can be a visually appealing addition to your landscape, providing a rustic and natural charm.
However, it’s essential to consider both the advantages and disadvantages before opting for this material.
The porous nature of the material allows rainwater to penetrate through the surface, which reduces runoff and promotes better absorption into the soil.
This can help mitigate issues related to water accumulation and drainage, preventing the formation of puddles or erosion on the walkway.
- Low Maintenance
Unlike traditional concrete or paved walkways, they generally don’t require sealing or regular upkeep.
The natural composition of crushed granite allows it to withstand weather conditions, such as freezing and thawing, without significant deterioration.
Routine maintenance typically involves removing debris and occasional leveling to ensure a smooth walking surface.
- Potential Weed Growth
Over time, weed seeds can find their way into the crevices and gaps between the crushed granite particles.
If left unattended, weeds can detract from the overall appearance of the walkway and create additional maintenance tasks.
To address weed growth, it’s essential to take preventative measures during installation.
A layer of geotextile fabric placed beneath the crushed granite can act as a weed barrier while still allowing water to permeate.
Regularly inspecting the walkway and manually removing any emerging weeds can help maintain its aesthetic appeal.
- Uneven Surfaces
The particles can shift and settle over time, resulting in an irregular walking surface. This may be more noticeable in high-traffic areas or where water runoff occurs.
Proper installation and maintenance techniques often help to minimize unevenness.
Excavating the area and creating a compacted base before applying the crushed granite can help ensure a more stable surface.
Periodically raking and leveling the walkway can help redistribute the crushed granite and reduce the occurrence of uneven spot
Crushed Granite Driveway Pros and Cons
A crushed granite driveway can offer several benefits. But it also has some drawbacks.
Crushed granite is typically more affordable compared to other driveway materials such as concrete or pavers.
It allows homeowners to achieve a visually appealing driveway without breaking the bank. If you’re working within a budget, crushed granite can be an attractive option.
It’s a natural material that’s mined and processed with minimal energy consumption.
By using crushed granite, you reduce the need for synthetic or manufactured materials.
Its permeability also allows rainwater to infiltrate the ground, minimizing water runoff and contributing to better water management on your property.
- Durability Issues
While crushed granite can withstand normal vehicle traffic, it may not be as durable as materials like concrete or asphalt.
Heavy vehicles or excessive use can cause the surface to shift or become compacted, resulting in an uneven and potentially less stable driveway.
If you anticipate heavy use or have large vehicles, you may need to consider alternative materials for better longevity.
How to Harden Decomposed Granite
Hardening decomposed granite is an important step to enhance its stability and mitigate issues such as shifting or erosion.
By implementing effective techniques, you can create a firmer and longer-lasting surface. Below are some practical tips for hardening DG.
Stabilizers are additives that can be mixed with decomposed granite to improve its cohesion and stability.
These products often come in liquid or powder form and work by binding the particles together.
Stabilizers help reduce the movement of decomposed granite and enhance its load-bearing capacity.
When using these additives, follow the manufacturer’s instructions regarding the appropriate application rate and mixing process.
It typically involves mixing the stabilizer with the decomposed granite thoroughly, ensuring even distribution.
Afterward, compact the mixture using a plate compactor or roller to achieve maximum density.
Another way to harden decomposed granite is by incorporating binding agents into the material.
Binding agents, such as various types of resins or organic materials, create a stronger bond between the granite particles, reducing movement and enhancing stability.
The selection and application process for binding agents may vary depending on the specific product.
Some binding agents require mixing with water or other additives, while others come pre-mixed and ready to use.
It’s important to follow the manufacturer’s instructions carefully to ensure proper application.
Controlling moisture levels is important when hardening decomposed granite.
Excessive moisture can cause the material to become loose and unstable, while insufficient moisture can hinder the binding process.
Aim for a moisture content that allows for optimal compaction and binding.
Before applying stabilizers or binding agents, ensure that the decomposed granite is slightly damp but not overly saturated.
Lightly moistening the material can help facilitate the binding process and improve compaction results.
However, avoid excessive watering or working with decomposed granite during heavy rainfall, as it may compromise the hardening process.
Proper compaction is essential to achieve a hardened decomposed granite surface. Use a plate compactor or roller to compact the material thoroughly.
This process helps eliminate air gaps, increases density, and enhances stability.
Start compacting from one end of the area and work your way toward the other end in overlapping passes.
Pay attention to any low spots or uneven areas and make additional passes as necessary. Proper compaction ensures a more solid and stable DG surface.
