Product Information

Full details

The Ecoscape Adjustable Pedestal is designed for professional landscapers and DIY deck builders who require a precise, level substructure for composite or timber decking. These pedestals excel at transforming uneven ground, balconies, or flat roofs into stable foundations, though they require a firm, load-bearing surface to ensure long-term stability and to prevent structural settling.

FAQs

Can I use these pedestals on soil or grass?

It is not recommended. These are designed for hard, stable surfaces like concrete, stone, or pavers. If used on soft ground, they will likely sink over time.

How much weight can each pedestal support?

While capacity varies based on height, they are designed to support standard residential deck loads. Refer to your specific joist span requirements for safety.

Are these pedestals resistant to frost?

Yes, the materials used are chosen for their durability in fluctuating outdoor temperatures and resistance to moisture-related degradation.

Can these be fixed down to the floor?

Most installations rely on the weight of the frame to keep them in place, but you should check local building regulations if the deck is subject to high wind uplift.

Do I need any special tools to adjust them?

No, they are designed to be adjusted by hand, though a spirit level is essential for ensuring accuracy during the setup process.

Troubleshooting

The deck feels bouncy or unstable

Check that all pedestals are touching the ground surface firmly. You may need to add more pedestals to reduce the span between support points.

Pedestal height is difficult to adjust

Clear away any grit or debris from the threads of the adjustment collar, then apply a small amount of silicone lubricant if necessary.

Pros and Cons

Pros

  • High degree of height customization within the specified range
  • Promotes healthy airflow beneath the deck boards
  • Simplifies installation on uneven sub-surfaces like balconies or rooftops
  • Heavy-duty construction ensures long-term stability

Cons

  • Requires a solid, non-compressible surface for installation
  • Limited to a specific height adjustment window
  • May require additional structural bracing if height is extended to the maximum limit

Setup, Compatibility & Care

  1. Preparation: Ensure the surface area is clean, stable, and capable of supporting the dead load of the deck structure and the live load of people.
  2. Layout: Determine the spacing between pedestals based on the thickness of your joists to prevent sagging.
  3. Adjustment: Rotate the pedestal collar to reach the desired height. Verify the level using a spirit level across multiple joists.
  4. Compatibility: These are designed for standard timber or composite joist profiles. Ensure the width of your joist fits within the pedestal head.
  5. Maintenance: Periodically check that no pedestals have shifted due to ground movement or thermal expansion. Keep the area underneath clear of debris to maintain proper drainage.
