How to Build a Floating Deck on Uneven Ground

Building a floating deck is a great way to enhance your outdoor space, especially if you have uneven terrain. Unlike traditional decks that are anchored to structures, floating decks rest independently and can adapt to the natural contours of your yard. This tutorial provides detailed steps to help you create a visually appealing and functional floating deck.
Materials Required
- Decking boards (select between composite or wood)
- Post anchors or concrete blocks for the foundation
- Leveling shims to adjust height
- Deck screws for secure fastening
- Landscape fabric to prevent weeds
- Gravel or a similar base material
Essential Tools
- Measuring tape for precise dimensions
- Level to ensure even surfaces
- Circular saw or handsaw for cutting boards
- Screwdriver for fastening screws
- Drill to create pilot holes
- Shovel for site preparation
Steps to Construct a Floating Deck
Step 1: Plan Your Deck
Choose the deck’s size and ideal location, considering visual appeal, functionality, and accessibility. Create a rough sketch to visualize your design.
Step 2: Prepare the Site
Clear the construction area by removing grass, weeds, and debris. On significantly uneven ground, use a shovel to level some areas to create a stable foundation.
Step 3: Lay the Foundation
Choose between post anchors or concrete blocks for your foundation. If using concrete blocks, arrange them in a grid, spaced about four feet apart, and ensure all blocks are flat with a level.
Step 4: Install the Deck Frame
Construct the frame using treated lumber for increased durability. Secure the outer frame pieces to the foundation with screws. For larger decks, add extra support beams in the center as necessary.
Step 5: Install the Decking
Cut the decking boards to size and lay them perpendicular to the frame. Ensure a small gap between the boards for drainage and expansion. Firmly attach the boards to the frame using deck screws.

Step 6: Add Final Touches
After all boards are installed, check for a level and even surface. Consider adding railings or other features to enhance safety and aesthetics.
Step 7: Maintenance Tips
Regularly inspect your floating deck for wear and tear, particularly if exposed to the elements. Remove debris, tighten any loose screws, and maintain a safe surface for use.
Conclusion
Building a floating deck on uneven ground can be manageable with the right materials, tools, and step-by-step instructions. Enjoy your new outdoor space!
