12x20 Floating Deck Material List: Top Choices for Durability & Beauty

Whether you're building a new deck or replacing an old one, selecting the right materials is crucial for both aesthetics and longevity. When it comes to a 12x20 floating deck, the choice of materials can significantly impact its durability, functionality, and visual appeal. Let's delve into the key components and popular materials for a floating deck of this size.

Before we dive into specific materials, let's briefly explain a floating deck. Unlike ground-level decks, floating decks do not require footings or anchors. Their weight is supported by a frame that rests on pads or piers, making them easier to install and more adaptable to varied landscapes. Now, let's explore the essential elements and their respective materials.

Decking Material Options

Decking boards are the most visible part of your floating deck, setting its tone and aesthetic appeal. There are three primary materials to choose from, each with its unique characteristics:

1. Pressure-treated lumber - Affordable and widely available, pressure-treated lumber offers good longevity with proper maintenance. It's suitable for budgets and can be stained or painted to match your desired look.

Benefits of Pressure-treated Lumber

Pros: Cost-effective, readily accessible, and can be stained or painted.

Cons: Requires regular maintenance, may warp or crack over time, and has a less refined look compared to other materials.

Alternatives to Pressure-treated Lumber

If you're looking for high-end or low-maintenance options, consider these alternatives:

• Composite materials - Made from recycled plastics and waste wood, composites offer excellent durability, low maintenance, and a wide range of colors and styles.
• Cedar and redwood - Naturally resistant to rot and insects, these woods provide a high-end look without the need for pressure treatment or painting. They've higher upfront costs but may outlast pressure-treated lumber.

Framing and Support Materials

Floating decks require a robust frame to support the decking boards and maintain stability. The primary materials for deck framing are:

1. Pressure-treated lumber - Commonly used for its affordability and availability, pressure-treated lumber is adequate for supporting decking boards and providing structure.

Pressure-treated Lumber for Framing

Pros: Cost-effective, widely available, and provides sufficient structural support.

Cons: Requires regular maintenance, may warp or crack over time, and has lower aesthetic appeal compared to other materials.

Other Framing Materials

If you're looking for improved durability or a more refined look, consider these alternatives:

• Cedar and redwood - With their natural rot resistance, these woods can provide longevity while maintaining a high-end appearance.
• Metal framing - Galvanized or stainless steel offers exceptional durability, low maintenance, and improved longevity compared to wood. It's more expensive but may be worth the investment for larger decks or harsh climates.

Pier Blocks and Pads

Pier blocks or pads elevate your floating deck and prevent direct contact with the ground, reducing moisture and decay. They also provide stability and leveling support. Popular materials for pier blocks and pads include:

1. Concrete blocks - Inexpensive and readily available, concrete blocks offer sturdy support but have a less refined appearance.

Benefits of Concrete Blocks

Pros: Cost-effective, widely accessible, and provide sufficient stability for small to mid-sized decks.

Cons: Less aesthetically pleasing, may crack or crumble over time, and can't be adjusted easily for leveling.

Alternative Pier Block Materials

For improved aesthetics or adjustability, consider these options:

• Plastic pier blocks - Lightweight, easy to adjust, and resistant to rot, mildew, and insects. They also provide good stability and blend in with various decking materials.
• Hollow concrete pier blocks - More durable than solid blocks, hollow concrete pier blocks can be filled with gravel for increased weight and stability. They also have a more refined appearance.

When selecting materials for your 12x20 floating deck, weigh the pros and cons of each option, considering factors such as cost, aesthetics, maintenance, and durability. A well-planned material choice will ensure you enjoy your outdoor living space for years to come. Happy building!
