Best Gravel for Underneath Deck: Types & Benefits

When it comes to enhancing the aesthetic appeal and functionality of your deck, choosing the right type of gravel to place underneath is a crucial decision. Not only does it impact the overall look of your outdoor space, but it also plays a significant role in drainage, safety, and maintenance. This article will guide you through the various types of gravel, their unique characteristics, and the factors to consider when selecting the perfect fit for your deck.

Before delving into the types of gravel, it's essential to understand the purpose of using gravel under your deck. Primarily, gravel serves as a barrier between the deck and the ground, preventing moisture buildup and wood rot. It also facilitates drainage, making it easier to clean and maintain your deck. Additionally, gravel can enhance the visual appeal of your outdoor space, complementing your deck's design and creating a cohesive look.

Understanding Different Types of Gravel

Gravel comes in various shapes, sizes, and colors, each with its unique advantages and applications. Familiarizing yourself with these types will help you make an informed decision when choosing the best gravel for your deck.

One of the most common types of gravel is pea gravel, characterized by its small, smooth, round pebbles. Typically, pea gravel is available in various colors, including earthy tones like brown and gray, as well as more vibrant hues such as red and green. Its smooth texture makes it comfortable to walk on barefoot, making it an excellent choice for decks surrounding pools or patios.

Pea Gravel: Pros and Cons

Pea gravel offers several benefits when used under decks. Its small size allows it to pack down tightly, creating a stable surface that's easy to walk on. Additionally, pea gravel's smooth texture makes it less likely to stick to shoes or paws, reducing the amount of gravel tracked into your home. However, pea gravel can be more expensive than other types of gravel, and its small size may not provide adequate drainage in areas with heavy rainfall.

Another popular choice for decks is crushed stone, which is typically angular and rougher in texture than pea gravel. Crushed stone is available in various sizes, from small (known as #10) to large (known as #89). Larger sizes of crushed stone, such as #57 and #89, are often used under decks due to their excellent drainage properties and ability to support heavy loads.

Crushed Stone: Pros and Cons

Crushed stone offers superior drainage compared to pea gravel, making it an excellent choice for decks in areas with high rainfall or snowmelt. Its angular shape allows water to flow freely through the gravel, preventing moisture buildup beneath the deck. Additionally, crushed stone is generally less expensive than pea gravel. However, its rough texture can make it uncomfortable to walk on barefoot, and it may be more likely to stick to shoes and paws, increasing the risk of tracking gravel into your home.

In addition to pea gravel and crushed stone, other types of gravel, such as river rock and washed clean stone, can be used under decks. River rock is smooth and rounded, similar to pea gravel, but typically larger in size. Washed clean stone is a type of crushed stone that has been processed to remove any fines or dust, resulting in a cleaner, more uniform appearance.

Factors to Consider When Choosing Gravel for Your Deck

When selecting the perfect gravel for your deck, there are several factors to consider to ensure you make the best choice for your specific needs and preferences.

First and foremost, consider the drainage requirements of your deck. If your deck is located in an area with high rainfall or snowmelt, opting for a gravel with excellent drainage properties, such as larger crushed stone, may be necessary. Conversely, if your deck is in a drier climate or has adequate drainage systems in place, a smaller gravel, like pea gravel, may be sufficient.

Drainage and Size

Gravel size plays a crucial role in drainage. Larger gravel allows water to flow more freely through the material, while smaller gravel may not provide adequate drainage in areas with heavy rainfall. When choosing gravel for your deck, consider the size of the gravel in relation to the drainage needs of your specific location.

Another essential factor to consider is the aesthetic appeal of the gravel. Choose a gravel that complements the color and style of your deck, as well as the overall look of your outdoor space. For example, earthy tones like brown and gray can create a natural, rustic look, while more vibrant hues can add a pop of color to your deck.

Aesthetics and Color

Gravel color can significantly impact the visual appeal of your deck. When selecting gravel, consider the overall color scheme of your outdoor space and choose a gravel that complements or enhances that scheme. Additionally, think about the texture and shape of the gravel, as these factors can also contribute to the overall aesthetic of your deck.

Cost is another crucial factor to consider when choosing gravel for your deck. Gravel prices can vary significantly depending on the type, size, and color. To ensure you stay within your budget, research the cost of various gravel options in your area and compare prices from different suppliers.

Cost and Budget

While it's essential to stay within your budget, it's also important to invest in high-quality gravel that will last and require minimal maintenance. Cheaper gravel options may not be as durable or aesthetically pleasing as more expensive options, and they may require more frequent replacement or maintenance. When comparing prices, consider the long-term value of each gravel option and choose the best balance between cost and quality.

Finally, consider the maintenance requirements of the gravel you choose. Some gravel types may require more frequent cleaning or replacement than others. For example, pea gravel may need to be topped off more frequently than larger crushed stone, as it can shift and settle over time. When selecting gravel for your deck, consider the maintenance requirements and choose a gravel that fits well with your lifestyle and available time.

Maintenance and Longevity

Maintaining your deck's gravel layer is essential for ensuring its longevity and functionality. Regular cleaning and occasional top-offs can help keep your gravel looking its best and performing at its peak. When choosing gravel for your deck, consider the maintenance requirements and select a gravel that is easy to clean and maintain.

In the end, choosing the right type of gravel for your deck involves a careful consideration of factors such as drainage, aesthetics, cost, and maintenance. By taking the time to research and compare various gravel options, you can select the perfect gravel to enhance the beauty and functionality of your deck while meeting your specific needs and preferences.
