Yes, you generally floating deck do you use beams. Especially if you want to ensure stability, support, and durability over time. However, whether beams are essential or optional depends on the size, weight load, and purpose of the deck. Constructing a floating deck is a popular project for DIY enthusiasts, but understanding when to use beams is key to creating a safe and long-lasting structure. This comprehensive guide explores the role of beams, how they impact construction, and what alternatives you might consider.

Understanding Floating deck do you use beams
A floating deck is a standalone structure that “floats” slightly above the ground, not anchored to a house or any other building. Unlike raised or attached decks, floating decks are usually installed using deck blocks or concrete pads, offering flexibility in placement and ease of installation. This design makes them ideal for spaces where you want a low-profile outdoor platform, and it’s why they’re a favorite for DIY builders.
Pros and Cons of Floating Decks
Pros | Cons |
Easier and quicker to install | May require more support for stability |
Generally cheaper than raised decks | Can shift over time without proper anchoring |
No need for building permits in most areas | Less elevation means reduced airflow underneath |
Great for uneven terrain | Potential water drainage issues |

The Importance of Beams in Deck Construction
Beams are horizontal support components that run across a deck, providing essential structural integrity and helping distribute weight evenly across the surface. Their role is particularly critical in larger decks, where the weight and size require additional reinforcement.
Deciding whether or not to use beams hinges on factors like deck size, terrain, and the weight it’s expected to hold. For smaller decks or those that won’t bear heavy loads, beams may not be strictly necessary. However, for anything over 10 feet wide or long—or if the deck will support heavy furniture, planters, or a grill—beams are highly recommended.
Myths About Building Floating Decks Without Beams
There’s a common belief that “floating decks without beams” are feasible if the structure is small enough, but this is a misconception. Even smaller decks benefit from the stability and longevity that beams provide, reducing the likelihood of sagging or shifting over time.
Choosing the Right Beams for Your Project
Selecting appropriate beams is crucial to the success of your deck. The size of the beam should correspond to the deck’s dimensions and the load it’s expected to handle. Below is a guide to help choose the correct beam size for various deck sizes:
Deck Size | Recommended Beam Size | Span (Distance Between Supports) |
Up to 10×10 ft | 2×6 | 10 feet |
10×10 to 12×12 ft | 2×8 | 12 feet |
12×12 to 14×14 ft | 2×10 | 15 feet |
Material Considerations for Beams
- Pressure-Treated Lumber is the go-to choice for most outdoor projects due to its durability, affordability, and resistance to insects and rot.
- Cedar offers natural resistance to decay and a beautiful finish but is pricier and requires more maintenance.
- Composite Materials are known for their longevity and minimal upkeep, though they come with a higher upfront cost.
Guide to Installing Beams
The first step in constructing a stable deck is preparation. Before starting, gather tools like a level, measuring tape, saw, and deck screws. Having the right materials, including appropriate beams, will make the process smoother.
Laying Out the Structure: Begin by marking out the deck’s perimeter using stakes and string. Ensuring accurate measurements at this stage is crucial for a successful build.
Setting Up and Leveling the Beams: Place the beams on deck blocks or concrete pads, adjusting as needed to keep them level. This will provide a strong foundation for your joists and decking boards.
Adding Joists for Extra Support: Once the beams are in place, joists are installed perpendicular to the beams. They should be spaced 12 to 16 inches apart to adequately support the decking material.
Making Final Adjustments: After installation, double-check the beam alignment, ensuring everything is level and secure. Reinforce any areas where the beams meet the deck’s edge to prevent movement.
Exploring Alternatives to Beams
Not all floating decks require traditional beams. Some homeowners opt for alternatives like deck blocks, especially for smaller or ground-level decks. These are pre-cast concrete blocks that support joists directly, offering a simpler and more cost-effective solution for light-duty decks.
Ground-level platforms, for instance, can forego beams if the terrain is already flat and stable. Joists can be placed directly on deck blocks, but this approach may limit the deck’s lifespan compared to using traditional beams.
Cost and Investment Considerations
The cost of beams can vary widely depending on material and size. Here’s a breakdown of potential expenses:
- Pressure-Treated Wood: $2 – $3 per linear foot.
- Cedar: $6 – $8 per linear foot.
- Composite Beams: $12 – $15 per linear foot.
While using beams may increase the initial investment, it often pays off by extending the deck’s lifespan. Labor costs also tend to rise slightly when beams are involved due to the added complexity, but the benefits of increased stability are substantial.
Expert Insights and Avoiding Common Pitfalls
Professionals emphasize the importance of selecting beams based on your deck’s specific needs. Here are a few insights to consider:
- Ensure you’re using the correct size and spacing for beams. Undersized beams can lead to sagging.
- Leveling is crucial; uneven beams can cause decking boards to warp or create a tripping hazard.
- Proper anchoring using galvanized bolts is necessary for long-term stability, particularly in areas prone to wind or shifting soil.
Avoid common mistakes like skimping on materials or ignoring weight load calculations. Both errors can lead to structural failure over time, turning a DIY project into a costly repair.
Conclusion
When constructing a floating deck, using beams is often the best approach for durability, stability, and overall quality. While it’s possible to build a smaller deck without beams, most projects benefit significantly from the added support. Choosing the right materials and spacing is essential for ensuring your deck stands the test of time. For a successful DIY deck project, investing in quality beams is a wise decision that will pay off in safety and longevity.
Frequently Asked Questions
What Size Beams Should I Use for a Floating Deck?
For most decks, a 2×6 beam will suffice for spans under 10 feet, while 2×8 and 2×10 beams are recommended for larger projects.
How Far Apart Should Beams Be on a Floating Deck?
Spacing generally falls between 4 to 6 feet apart, depending on the deck’s width and the load requirements.
Can I Build a Floating Deck Without Beams?
For small decks or those not expected to bear heavy loads, beams might be optional. However, they’re usually recommended for enhanced support.
What’s the Difference Between Beams and Joists?
Beams are primary horizontal supports running the length of the deck, while joists are smaller, secondary supports that attach perpendicular to the beams.
How Do I Anchor Beams for a Floating Deck Properly?
Anchoring requires using high-quality bolts or fasteners that resist rust and corrosion, ensuring a firm and stable connection between the beams and other structural components.
