How To Install Composite Wood Decking on Uneven Ground





Creating a stunning and level outdoor space is achievable even on uneven ground by using MexyTech composite wood decking with Mexybase adjustable pedestals. These versatile pedestals can be adjusted to heights ranging from 36 to 607mm, accommodating various terrains. The ability to adjust horizontally up to a maximum tilt of 45 degrees ensures that your deck is not only aesthetically pleasing but also structurally sound on uneven surfaces. Here's a comprehensive guide on how to install composite wood decking on uneven ground:

Materials Needed:

  1. MexyTech WPC Composite wood decking

  2. Adjustable pedestals

  3. Joist and clips

  4. Level

  5. Tape measure

  6. Saw (for cutting)

  7. Composite deck tiles (optional)

Installation Steps:

1. Assess the Terrain:

  • Survey the uneven ground to identify high and low points.

  • Take note of any significant slopes or variations in the landscape.

2. Plan the Layout:

  • Plan the layout of your deck, considering the natural contours of the ground.

  • Determine the number of adjustable pedestals needed based on the slope and dimensions.

3. Install Adjustable Pedestals:

  • Place the adjustable pedestals at strategic locations, ensuring they are evenly spaced.

  • Adjust the height of the pedestals according to the slope, using a level for accuracy.

4. Lay the Composite Decking Tiles (Optional):

  • If using deck tiles, lay them on top of the adjustable pedestals.

  • Ensure a tight and secure fit between tiles.

5. Cut Composite Decking Boards:

  • Use a saw to cut composite decking boards to the required lengths.

  • Precision is key, especially for edges and corners.

6. Attach Composite Boards:

  • Begin attaching the composite decking boards to joist on the adjustable pedestals using screws.

  • Ensure even spacing between boards for drainage and expansion.

7. Check for Level and Adjust:

  • Regularly check for level and adjust the pedestals as needed to maintain a level surface.

  • Use the level to confirm that the entire deck is even.

8. Complete the Installation:

  • Continue attaching the composite boards until the entire deck is covered.

  • Double-check all screws and fastenings for security.

9. Optional Steps for Low Decks:

  • For decks close to the ground, consider adding a layer of gravel or sand underneath for proper drainage.

  • Include a weed barrier to prevent vegetation growth.

10. Maintenance Tips:

  • Composite wood decking is low-maintenance, but periodic cleaning is recommended for longevity.

  • Use a mild detergent and a soft brush to clean the surface.
