The term “landscape drain rock” typically refers to a type of gravel or crushed stone that is used in landscaping and drainage applications. The best landscape drain rock will depend on the specific needs of your project, but common options include crushed granite, crushed limestone, and pea gravel.

  1. Decomposed/Crushed Granite: Crushed granite is a durable and permeable option that allows water to flow through it easily. It’s a popular choice for landscape drain rock due to its stability and resistance to erosion.
  2. Crushed Limestone: Similar to crushed granite, crushed limestone provides good drainage capabilities and is often used in drainage systems and around areas where water runoff needs to be controlled.
  3. Pea Gravel: Pea gravel consists of small, rounded stones that allow water to pass through quickly. It’s an attractive option for landscaping projects, but its smaller size may not be as effective in some drainage applications compared to crushed stone.

How Landscape Drain Rock is Used:

  1. French Drains: Landscape drain rock is commonly used in French drains, which are underground drainage systems designed to redirect excess water away from specific areas, such as near building foundations or low-lying spots in the yard. The drain rock is placed in a trench along with a perforated pipe, allowing water to flow through the rock and into the pipe, which then carries the water away.
  2. Dry Creek Beds: In landscaping, landscape drain rock can be used to create aesthetically pleasing dry creek beds. These are decorative features that mimic the appearance of a natural stream or creek but only carry water during heavy rainfall or when irrigation systems are used. The drain rock allows water to flow through the creek bed, preventing standing water and potential flooding.
  3. Garden Paths: Landscape drain rock can be used to create paths and walkways in gardens and landscapes. The rock allows water to permeate through the surface, reducing runoff and preventing puddles.
  4. Surface Drainage: In areas where surface drainage is needed, such as sloped lawns or garden beds, landscape drain rock can be used as a top layer to facilitate water absorption and prevent erosion.

When choosing the best landscape drain rock for your project, consider factors like the amount of water you need to manage, the soil conditions, and the overall aesthetic you want to achieve. Additionally, always ensure that the chosen drain rock is suitable for your specific drainage needs and meets any local regulations or building codes.

What is Decomposed Granite?

Decomposed granite (often abbreviated as “DG”) is a type of granitic rock that has weathered and broken down into small, fine particles over time. It is the result of the natural erosion and disintegration of solid granite rocks. Decomposed granite is commonly used in landscaping and construction projects due to its versatility and attractive appearance.

Characteristics of Decomposed Granite:

  1. Particle Size: Decomposed granite consists of small, granular particles that range in size from fine sand-like material to small gravel-sized pieces. The particle size can vary depending on the specific source of the decomposed granite.
  2. Colors: Decomposed granite typically comes in various earthy colors, including shades of brown, gray, beige, and gold. The colors can vary depending on the mineral composition of the original granite and the region it comes from.
  3. Permeability: One of the key features of decomposed granite is its permeability. The small, porous particles allow water to pass through easily, making it an excellent material for drainage purposes.

Uses of Decomposed Granite:

  1. Pathways and Walkways: Decomposed granite is often used to create pathways and walkways in gardens, parks, and residential landscapes. When compacted, it forms a stable surface that allows for easy walking while still allowing water to soak into the ground.
  2. Patios and Outdoor Living Areas: Decomposed granite can be used to create patio areas and other outdoor living spaces. Its natural appearance and permeability make it an attractive alternative to concrete or other solid surfaces.
  3. Landscaping Mulch: When spread over the soil, decomposed granite can act as a natural mulch, helping to retain moisture, suppress weed growth, and regulate soil temperature.
  4. Garden Borders: Due to its loose nature, decomposed granite can be used to create defined borders around garden beds and other landscape features.
  5. Erosion Control: Because of its ability to allow water to pass through easily, decomposed granite can be used in erosion control applications, such as stabilizing slopes and preventing soil erosion.
  6. Base Material: Decomposed granite can serve as a base material for various construction projects, such as paving driveways or installing artificial turf.

It’s important to note that while decomposed granite is a popular landscaping material, it is not suitable for all applications. In high-traffic areas, it may become loose and require periodic maintenance to keep it compacted. Additionally, when using decomposed granite in pathways or high-traffic areas, using a stabilizer (a binding agent) can help to improve its durability and prevent excessive erosion.
