Royal Deck Expert Deck Builder > New Decks > 5 Types of Deck Foundations: Which One is Right for Your Home?

Building a deck for your Atlanta home is an exciting prospect that can enhance your outdoor living space and increase your property value. However, before you select materials or decide on the location, it’s important to understand the foundation of any great deck: the deck footings. The right choice in deck footings not only helps your deck’s stability and safety but also its compliance with local building codes.

In this article, we will explore five types of deck footings suited to various needs and landscapes. Each type of footing offers different advantages, whether your deck is a grand structure attached to your home or a charming standalone addition to your garden. From understanding the load-bearing capacity required for your deck’s dimensions to navigating Atlanta’s specific building regulations, choosing the right type of footing is a complex decision that can have lasting impacts on the safety and durability of your deck.

What Are Deck Footings?

Deck footings are a critical component of deck construction—they form the foundation that supports the entire structure. Essentially, footings are installed deep into the ground, providing a stable base that distributes the deck’s weight evenly and prevents it from shifting or collapsing. There are various types of footings, each designed to address specific soil conditions, weight requirements, and environmental factors. Here are some reasons why deck footings are important:

Stability and Safety

The primary role of deck footings is to provide stability. By anchoring the deck securely to the ground, footings ensure that the structure can withstand the forces of nature, from strong winds to heavy snow loads. This stability is crucial not only for the longevity of the deck but also for the safety of everyone who uses it. A well-footed deck minimizes the risk of structural shifts and collapses, which are vital considerations in areas prone to extreme weather or seismic activity.

Weight Distribution

Decks must withstand the weight of people, furniture, grills, and sometimes even hot tubs. Footings distribute this load across a broader area, preventing the deck from sinking or tilting into the soil. Properly installed footings take into account the bearing capacity of the soil, ensuring that the deck remains level and intact over time.

Compliance with Building Codes

Most local building codes require footings for any deck attached to a home or any freestanding deck that rises above a certain height. These regulations ensure that all decks are constructed to meet safety standards that can withstand local environmental conditions. Deck compliance with these codes is not only a legal requirement but also a guarantee of quality and safety.

Prevention of Frost Heave

In colder climates, the freeze-thaw cycle can cause the ground to heave, potentially uplifting improperly anchored structures. Deck footings that extend below the frost line can help prevent this movement by keeping the deck’s base stable throughout the year, regardless of temperature fluctuations.

Enhances Longevity and Aesthetics

A well-built deck foundation extends the life of your deck by preventing premature wear and damage. Additionally, a stable deck maintains its aesthetic appeal, free from uneven planks or unsightly leans that can occur from settling or poor support.

5 Types of Deck Footings: A Foundation of a Safe Deck

1. Precast Cement Blocks

Precast cement blocks are a straightforward and economical option for deck footings, especially favored for less complex or lower-to-the-ground decks. These blocks are factory-made, ensuring consistency and reliability.

Concrete block foundations are designed to be placed directly on stable, level ground, making installation quick and hassle-free. While they are cost-effective and easy to use, they may not be suitable for taller structures or decks requiring a deep, frost-proof foundation due to their relatively lighter weight and lower stability compared to other footing types.

2. Poured Concrete Footings

Poured concrete footings are the go-to for a durable and strong deck foundation. This method involves excavating holes to the appropriate depth—often below the frost line—and then filling them with concrete. This process creates a permanent and robust base for any deck, particularly beneficial for larger, heavier, or multi-level decks that demand greater support.

Although pouring concrete offers a highly stable foundation, it requires more preparation, time, and potentially higher costs due to the labor and materials involved. The customization ability of poured footings allows them to be adapted for various deck shapes and sizes, providing a tailored solution to unique deck designs.

3. Precast Stackable Cement Footings

For those seeking a balance between stability and ease of installation, precast stackable cement footings provide an effective solution. These footings are modular, allowing for height adjustments to ensure your deck is perfectly level. This feature is particularly useful in uneven terrains where minor height modifications are necessary.

Stackable footings are also quick to set up since they don’t require curing time like traditional poured concrete, making them a time-saver on the construction site. They offer a solid foundation with the added benefit of adjustability and faster installation, making them suitable for a wide range of deck projects.

4. Buried Post Footings

Buried post footings are ideal for establishing a secure and enduring base for your deck. This type involves embedding posts deep into the soil, extending below the frost line to anchor the deck securely and prevent movement due to frost heave.

These footings are particularly effective in windy areas or uneven soil conditions where additional stability is crucial. Although the installation of buried post footings is more labor-intensive and requires precise execution, the payoff is a supremely stable and long-lasting deck structure.

5. Screw Piles

Screw piles represent a modern and highly efficient footing choice that provides exceptional stability with minimal disruption to the landscape. These footings are screwed into the ground using specialized equipment, which allows for quick and clean installation.

Screw piles are especially useful in areas with problematic soil conditions or when a quick installation is desired. They can be loaded immediately, reducing project time significantly. The strength and speed of installation make screw piles an increasingly popular choice for both residential and commercial deck projects.
