Best Stone for Under Deck: Top Choices for Durability & Appearance

When it comes to building a deck, one crucial decision often overlooked is the type of stone to place underneath. This layer, known as a deck footing, plays a vital role in supporting your deck's structure and ensuring its longevity. But with numerous options available, choosing the best stone can be overwhelming. Let's delve into the world of deck footings and explore the best stones to use, their benefits, and how to choose the right one for your project.

Before we dive into the types of stones, it's essential to understand why using stone under your deck is crucial. Stone footings provide a stable base, preventing your deck from settling or shifting over time. They also promote proper drainage, preventing water from pooling and causing damage to your deck's structure. Now, let's explore the best stones to use for your deck footing.

Best Stones for Deck Footings

The ideal stone for a deck footing is durable, drains well, and is readily available in your area. Here are three popular options that check all these boxes:

Crushed Stone

Crushed stone, also known as gravel, is a popular choice for deck footings due to its durability and drainage properties. It's typically made from limestone, granite, or trap rock, which are all strong and long-lasting materials. Crushed stone comes in various sizes, with #57 and #67 being the most common choices for deck footings. These sizes provide a good balance between drainage and stability.

When using crushed stone, it's essential to ensure proper compaction to create a solid base for your deck. This involves laying down a layer of stone, compacting it with a plate compactor, and then adding another layer. Repeat this process until you reach the desired height for your footing.

Concrete Blocks

Concrete blocks, or cinder blocks, are another popular option for deck footings. They provide excellent stability and can be easily stacked to create a solid base for your deck. Concrete blocks are typically used in conjunction with a layer of gravel to promote drainage and prevent water from accumulating around your deck's posts.

When using concrete blocks, it's crucial to ensure they are level and stable. You may need to use shims or fill voids with gravel to achieve a solid, even base. Additionally, consider using a gravel base underneath the blocks to further enhance drainage.

Pavers

Pavers are a more aesthetically pleasing option for deck footings, as they can be used to create a finished look underneath your deck. Interlocking concrete pavers are a popular choice, as they can be easily installed and provide excellent stability. Pavers also allow for proper drainage, as water can flow through the spaces between them.

When using pavers, it's essential to ensure they are level and stable. You may need to use a sand base to achieve a solid, even surface. Additionally, consider using a gravel base underneath the pavers to further enhance drainage and prevent the pavers from shifting over time.

Choosing the Right Stone for Your Deck Footing

Now that you're familiar with the best stones for deck footings, you may be wondering how to choose the right one for your project. Here are some factors to consider when making your decision:

Durability

The stone you choose should be durable enough to withstand the weight of your deck and any additional loads, such as snow or heavy furniture. Crushed stone, concrete blocks, and pavers are all strong and long-lasting materials that can handle the demands of a deck footing.

Drainage

Proper drainage is crucial for preventing water damage to your deck's structure. Choose a stone that allows water to flow through it easily, such as crushed stone or pavers. Concrete blocks can also be used with a layer of gravel underneath to promote drainage.

Availability and Cost

Consider the availability and cost of the stone in your area. Some stones may be more expensive or difficult to find, depending on your location. Be sure to research the cost and availability of each stone option before making a decision.

When it comes to building a deck, choosing the right stone for your footing is crucial for ensuring its longevity and stability. By understanding the best stones for deck footings and considering factors such as durability, drainage, and cost, you can make an informed decision that will serve your deck well for years to come. So, don't overlook this essential aspect of deck building – choose the best stone for your footing and enjoy your new outdoor space with confidence.
