Building your dream deck might seem like a daunting task but understanding and executing the crucial construction elements correctly is key. One of these essential elements includes the installation of deck footings. Deck footings provide the solid foundation that holds your deck in place, making it sturdy and reliable. So, figuring out how to create your deck’s foundational groundwork is an absolute must. That’s why in this blog, we will explore everything you need to know about deck footings including types, installation tips, and the importance of correct installation. Let’s jump in!

An Overview of Deck Footings

Deck footings are crucial elements in deck construction. They serve as the base that supports the deck's underlying structure ensuring its stability and safety. Basically, deck footings are designed to bear the load of the deck and distribute this weight evenly to the ground. It is important to size and position them correctly to prevent undue stress points or sagging in the deck’s structure. Installation of deck footings involves digging holes in the ground, pouring concrete, and then placing a post bracket on top once the concrete has solidified.

Types of Deck Footings

There are various types of deck footings available, each designed to suit different types of terrain, deck designs, and soil conditions.

  • Concrete Piers: These are the most common type of deck footings. Concrete is poured directly into a hole in the ground and an anchor is embedded within the concrete to hold the deck post.

  • Concrete Blocks: Seldom used nowadays, concrete blocks or deck blocks rest on top of the ground and can be a quicker, easier solution, especially for smaller, lighter decks.

  • Screw Piles: A popular choice for their strength and ease of installation, screw piles are twisted into the ground using machinery, providing a strong, secure footing. They are ideal for dealing with soft ground and high water tables.

Importance of Correct Deck Footing Installation

If you're wondering why putting emphasis on correctly installing deck footings is so important, here's why:

  • Safety: Deck footings are critical for the stability of the deck and hence everyone who uses it. Poorly installed footings could collapse causing injury.

  • Longevity: A well-installed deck footing helps increase the life span of your deck by providing a solid, stable base.

  • Legal requirements: Most areas have strict building codes and regulations for deck construction. Incorrectly installed footings may result in violation of these codes.

Installation Tips for Deck Footings

Correct installation of deck footings is a cornerstone for a sturdy and safe deck. Follow these tips:

  • Plan Ahead: You need to consider the location, size, and type of your deck, plus the type of soil in your yard. Each of these factors influences the type and size of the footings you'll need.

  • Follow Building Code: Ensure you adhere to local building codes. These can dictate depth, diameter, and other specifications for footings.

  • Hire a Professional: If you're a novice DIYer, it's suggested to hire a professional to avoid costly or dangerous mistakes.

Deck Footing Depth and Diameter

The depth and diameter of your deck footings are determined by a few factors, including the deck size, load it will bear, type of soil, and the local frost line. Generally, the depth of the footing must extend beyond the frost line to prevent shifting during freeze and thaw cycles.

Deck Footing Spacing

The empty space between footings is determined by the size of your deck and the weight it will carry. This spacing is crucial to the stability of the entire deck.

Understanding the functionality, types, importance, and correct installation of deck footings will ensure your deck remains secure and lasts for years. While you can often install deck footings yourself, consider hiring skilled contractors to ensure your deck is safe, sturdy, and abides by all local building codes. Happy Deck Building!

Frequently Asked Questions about Deck Footings

What is the purpose of deck footings?

Deck footings are an extremely crucial aspect of your deck's construction. They provide support and stability, serving as the foundation of your deck. By transferring the heavy load of your deck to the ground, they prevent the deck from sinking or shifting – issues that could cause damage or misalignment. They also prevent frost heave issues in cooler climates.

What are the different types of deck footings?

Deck footings come in several types, each suitable for different deck configurations and soil conditions. The most common types include concrete footings, which are poured into dug holes; precast piers, which are bought already cast and simply placed and backfilled; and helical piers, which are screwed into the ground for extra stability in certain conditions.

How deep should deck footings be?

The depth of your deck footings depends on the local building codes, frost line depths, and soil conditions. In general, they should be at least as deep as the frost line to prevent heaving, and must typically extend below the topsoil into the more stable subsoil. This often means a depth of at least 36 inches, but specific regulations can vary by location.

Are there any regulation size for deck footings?

Yes, the size and depth of deck footings are governed by local building codes, which are based on factors like soil type and loads. The size of the footing determines the load it can bear, so it must be properly sized to support your deck. Consulting a professional or local building inspector can provide exact specifications for your area and deck design.

Can you use deck blocks as footings?

Deck blocks can be used as footings in some circumstances, but they don't offer the same load-bearing capabilities or stability as traditional concrete footings. They're typically used for smaller, lighter constructions like free-standing decks and sheds. You should check with your local building code to see if deck blocks are permitted for your planned construction.

Can deck footings be adjusted?

Once deck footings are installed, adjusting them can be quite difficult. It's vital to get the placement and depth correct during installation to avoid later adjustments. If adjustments are absolutely necessary, it can involve jacking up the deck, excavating around the footing, moving or adjusting the footing, and then backfilling. Consult a professional if you find yourself in this situation.

How long does it take for deck footings to dry?

Concrete deck footings usually take about 24 to 48 hours to dry enough to be able to support some weight. However, full strength and stability is typically not achieved until about 28 days of curing time. Weather conditions, like humidity and temperature, can affect the drying time, so it may be best to budget extra time for this process to avoid any complications.

How far apart should deck footings be?

The spacing of deck footings is determined by the size and weight of the deck, the size and type of the support beams used, and load requirements from your local building code. On average, deck footings should be spaced between 4 to 8 feet apart, but the specific spacing for your deck should be calculated based on these factors.

Can deck footings be reused?

In some cases, if the footings are in good condition and meet current building codes, existing deck footings can be reused for a deck rebuild. However, their condition and suitability should be thoroughly evaluated by a professional before deciding to reuse them. If there is any doubt about their integrity, it's best to install new footings to ensure the stability and safety of your deck.

How to prevent frost heave for deck footings?

To prevent frost heave, your deck footings should be installed below your area's frost line depth. Similarly, using footings like helical piers, which can be installed deeper into the ground, can also provide additional prevention against frost heave. Ideally, you should consult with a local professional to make sure your deck footings are adequate to withstand frost heave.

Pros and Cons of Deck Footings

A Detailed Look at the Pros of Deck Footings

Durability

One of the primary advantages of deck footings is their durability.
