Choosing the best material is a crucial part of creating beautiful and functional paths and walkways. It can make or break your outdoor space’s overall design and utility, so finding durable and aesthetic options is essential. Decomposed granite (DG) has become an increasingly popular choice because of its versatility and visual appeal. The natural material brings together functionality and style! Let’s explore what makes DG pathways and walkways a fantastic idea.

What Is Decomposed Granite?

Decomposed granite, or DG, forms naturally when granite rock weathers and breaks down into dust-like particles. Since granite is rich in minerals like quartz, mica, and feldspar, DG comes in a variety of natural colors, such as brown, red, gold, gray, green, and tan. Unlike other granite types that are available in large blocks or slabs, DG is ultra-fine and provides a softer, more textured surface.

Take crushed granite, for example. It’s mechanically crushed and can’t match the distinct textures and compositions of naturally weathered DG. This adaptability makes DG a fantastic choice for creating walkways, driveways, garden trails, roads, patios, and more.

Benefits of Using Decomposed Granite for Pathways and Walkways

Decomposed granite pathways are known for their appeal and strength. Choosing a DG walkway over a crushed stone path or other types offers unique benefits.

Durability and Longevity

DG is made from natural granite that has broken down into tiny particles over time. This material is tough and can easily withstand heavy foot traffic and weather conditions, from hot summers to rainy winters. When you install a DG path properly, it can last for many years without significant wear and tear. Think of it as a durable, low-maintenance path that stands the test of time.

Low Maintenance Requirements

One of the best things about DG is that it’s very low maintenance. You don’t need to spend a lot of time or money to keep it looking good. If you notice any small issues, like minor erosion or a few weeds, they’re easy to fix. This means you can enjoy a neat and attractive pathway without much effort.

Cost-Effectiveness

DG is often more affordable upfront compared to materials like concrete or pavers. But the savings don’t stop there. Because it’s so durable and requires little maintenance, you won’t need to spend much on repairs or upkeep over the years. This makes DG a budget-friendly option both now and in the future.

Environmental Benefits and Permeability

DG is a permeable material, meaning water can pass through it instead of running off the surface. This helps prevent erosion, reduces the risk of flooding, and allows rainwater to soak back into the ground, replenishing groundwater supplies. By choosing DG, you’re making an environmentally friendly choice that supports sustainable landscaping practices.

With these benefits, decomposed granite is an excellent option for creating attractive, durable, and eco-friendly walkways and paths. It’s a practical choice that beginners can easily manage and enjoy.

Types of Decomposed Granite for Pathways

There are several types of decomposed granite, each with its unique properties.

  • Natural DG: This type of DG is ideal for gardening projects and tree landscaping, and you can use it similarly to mulch. Natural DG outlasts traditional wood mulch and deters unwanted animals.
  • Stabilized DG: This type of DG is best for driveways, pathways, and walkways. You bind this material with a stabilizer agent, and it will look and feel like an asphalt surface.
  • Resin-Coated DG: The strongest type of DG is resin-coated DG. You combine this with resin additives to form durable, permeable surfaces.

When choosing the appropriate type of DG, consider the specific use of the area and assess factors like foot traffic, drainage needs, and visual appeal.

Planning Your Decomposed Granite Pathway With a Landscape Designer

Plan your compressed granite walkway like any granite pathway. Think about where the path will go, its purpose, and how it will integrate with the rest of your landscape. Decide whether you want a curved or straight path to match your garden’s aesthetics. 

With the help of your landscape designer, measure the area and mark it with stakes and string to help you visualize the final result and ensure accuracy during installation.

How Landscape Contractor Installs a Decomposed Granite Pathway

Once you have decided that DG is the material you want and need and have completed the planning phase, the next thing to learn is how to install DG pathway or walkway. Here’s a guide to the process:

Step 1: Excavation and Base Preparation

The contractor begins by excavating the pathway area to a depth of about four to six inches, removing any grass, roots, or debris. They then compact the soil to create a stable base, ensuring a solid foundation for the pathway.

Step 2: Installing Edging to Contain the DG

Next, the contractor installs edging along the sides of the pathway to keep the decomposed granite in place. This edging can be made of metal, plastic, or wood, and is crucial for maintaining the pathway’s shape and preventing the DG from spreading.

Step 3: Laying and Compacting the Base Layer

A layer of crushed rocks or gravel is then laid down in the excavated area. This base layer is essential for drainage and stability. The contractor compacts the base layer to make sure it’s firm and level, providing a solid bed for the decomposed granite.

Step 4: Adding and Compacting the Decomposed Granite

The contractor spreads the DG evenly over the base layer to a depth of about two to three inches. They then compact the DG and lightly water the surface to help it settle. After allowing it to settle, they compact it again to ensure a smooth and firm pathway.

Professional landscape contractors use specialized tools such as rakes, shovels, wheelbarrows, and plate compactors to create smooth and even DG walkways. They also select high-quality edging and base layer materials and apply techniques perfected through years of experience to ensure a durable and attractive pathway.

Maintenance Tips for Decomposed Granite Walkways

Routine maintenance for a walkway decomposed granite includes keeping weeds and other debris from accumulating on the surface, looking out for pooling water, and occasionally refilling and compacting with fresh DG. Be mindful of freeze-thaw cycles in colder climates and consider more occasional watering in warmer climates.

If you notice significant erosion, settling, or other issues that you can’t address yourself, call your contractor for professional services.

Common Questions About Decomposed Granite Pathways

What Is the Difference Between a Crushed Granite Path and a Decomposed Granite Pathway?

The primary difference between crushed and decomposed granite is their composition and texture.

Crushed granite consists of larger pieces of granite that are mechanically crushed. As such, crushed granite pathways have a coarser texture, which can be harder on the feet. In contrast, decomposed granite is a finer material that results from the natural weathering of granite rock. DG pathways have a finer, smoother texture that is generally more foot-friendly.

The better choice between a crushed granite pathway and a DG pathway depends on personal preference and purpose.

Can Decomposed Granite Be Used for High-Traffic Areas?

Yes, you can use DG in high-traffic areas, especially when stabilized or resin-coated. These types of DG are stable, though they may require periodic redressing and recompacting.

How Do You Keep Decomposed Granite in Place?

Use a combination of proper installation techniques and ongoing maintenance to keep DG in place.

First, solid edging can help contain the DG and prevent it from spreading into adjacent areas. This edging can use materials like steel, wood, or bricks. Additionally, a stabilizing agent or resin can enhance the durability of the DG, reduce dust, and keep it compacted.

Regular maintenance is also crucial; rake the surface to fill in any low spots, keep the pathway clear of debris, and address drainage issues. Lastly, avoid using heavy machinery on the path to prevent displacement and erosion.

How Long Does a Decomposed Granite Walkway Last?

As landscaping material, DG can last up to 10 years with proper installation. However, factors such as climate, traffic, and maintenance can impact the longevity of walkways. For example, DG walkways may need more frequent redressing and recompacting in areas with heavy rain and snow. In high-traffic areas, regular maintenance and touch-ups may also be necessary to keep the pathway looking its best.
