A floating deck, also sometimes called a suspended deck, is a deck structure that isn't directly attached to the ground or a building's foundation. Instead, it sits on a system of supports, creating the illusion that it's floating above the surface. This creates a visually striking and often surprisingly simple design solution for various applications. This guide delves into the specifics of floating decks, explaining their construction, benefits, and considerations.
How is a Floating Deck Constructed?
The construction of a floating deck relies on a robust support system independent of the ground. This typically involves:
-
Footings: These are the foundational elements, often concrete piers or adjustable metal posts, buried beneath the ground. The depth and type of footing depend heavily on soil conditions and local building codes.
-
Support Beams or Piles: These extend upwards from the footings, providing the main structural support for the deck. They are typically made of pressure-treated lumber, steel, or composite materials, chosen for their durability and resistance to rot and decay.
-
Deck Joists: These horizontal beams run perpendicular to the support beams, creating a grid-like structure to support the decking boards.
-
Decking: The final layer consists of the actual decking material, which can range from pressure-treated wood to composite materials, or even natural stone or tile.
What are the Advantages of a Floating Deck?
Floating decks offer several advantages compared to traditional decks built directly on the ground:
-
Minimal Ground Disturbance: The construction process involves less excavation and landscaping disruption compared to decks built directly on the ground. This minimizes damage to existing vegetation and landscaping.
-
Improved Drainage: The space between the ground and the deck allows for better drainage, reducing the risk of water accumulation and rot.
-
Level Surface: Even on uneven terrain, a floating deck can be easily leveled by adjusting the height of the support posts.
-
Pest Control: The elevated design creates a barrier against pests and insects that might otherwise infest a ground-level deck.
-
Aesthetic Appeal: The suspended appearance adds a unique architectural element to any outdoor space, enhancing its visual appeal.
What are the Disadvantages of a Floating Deck?
While floating decks offer many benefits, there are some potential drawbacks to consider:
-
Higher Cost: The more complex construction process often results in a higher initial investment compared to ground-level decks.
-
Accessibility: Access to the underside of the deck for maintenance or repairs can be more challenging.
-
Potential for Movement: In areas prone to shifting soil or frost heaving, the floating deck might require additional stabilization measures to prevent movement or settling.
What Types of Materials are Used for Floating Decks?
A wide range of materials can be used for a floating deck, each offering unique properties and aesthetic qualities:
-
Pressure-Treated Lumber: A cost-effective and readily available option, but requires regular maintenance to prevent rot and insect damage.
-
Composite Decking: A low-maintenance, durable alternative to wood, often mimicking the look of natural wood.
-
Steel: Provides exceptional strength and durability, suitable for larger or heavier decks.
-
Concrete: Offers superior strength and longevity but is more expensive and requires specialized skills for installation.
How Much Does a Floating Deck Cost?
The cost of a floating deck varies significantly depending on factors such as size, materials, complexity of design, and labor costs. It's advisable to obtain multiple quotes from reputable contractors in your area to get an accurate estimate.
How Do I Maintain a Floating Deck?
Regular maintenance is crucial for prolonging the lifespan of your floating deck. This includes:
-
Cleaning: Regularly sweep or wash the deck to remove dirt and debris.
-
Inspection: Periodically inspect the deck for signs of damage or deterioration.
-
Repair: Address any damage promptly to prevent further issues.
-
Sealing (if applicable): Apply a protective sealant to wooden decking to protect it from the elements.
This comprehensive guide provides a thorough overview of floating decks, covering their construction, advantages, disadvantages, materials, costs, and maintenance. By understanding these aspects, you can make an informed decision about whether a floating deck is the right choice for your outdoor space. Remember to consult with a qualified contractor to ensure the safe and successful construction of your floating deck project.
