Product Information

Full details

The Ecoscape Composite Decking Adjustable Pedestal is designed for professional contractors and DIY enthusiasts who require a stable, level substructure for composite decking installations. By offering a precise height range of 30mm to 41mm, these pedestals effectively compensate for uneven ground or minor elevation needs, ensuring a flat finished surface. While these supports are highly durable, users must ensure the underlying ground surface is sufficiently compacted to prevent settling over time.

FAQs

Can I use these on soft soil?

No, these pedestals require a firm, stable surface like concrete or paving slabs. They should not be placed directly onto grass or loose dirt.

How many pedestals do I need?

The number of pedestals depends on your joist spacing and the load-bearing requirements of your deck design. Consult your joist manufacturer's guidelines for span specifications.

What is the maximum height?

These specific pedestals are adjustable between 30mm and 41mm.

Are these pedestals suitable for ground-level decks?

Yes, they are excellent for ground-level decks, as they provide necessary ventilation and separation between the joists and the ground.

Do I need to fix the pedestals to the ground?

For most floating deck applications, the weight of the completed frame is sufficient, but follow local building codes regarding anchoring if necessary.

Troubleshooting

Pedestal feels wobbly after adjustment

Ensure the base is resting flat on a solid surface and check that the locking mechanism is fully engaged.

Difficulty rotating the adjustment head

Clear any dirt or debris from the threads and ensure the weight of the joist is not resting entirely on the pedestal while adjusting.

Pros and Cons

Pros

  • Reduces installation time by simplifying the leveling process
  • Prevents direct contact between joists and the ground, reducing rot risks
  • Compact height profile ideal for low-clearance deck builds
  • Provides a uniform load distribution across the deck surface

Cons

  • Requires a solid, non-compressible surface underneath for maximum stability
  • Adjustment range is limited to 30mm-41mm
  • Not intended for use on soft, uncompacted soil or loose gravel without additional base preparation

Setup, Compatibility & Care

  1. Surface Preparation: Ensure the base surface is level, stable, and clear of debris.
  2. Layout: Position the pedestals along your joist run based on your framing plan.
  3. Adjustment: Place the joist on the pedestal and rotate the threaded head to reach the desired height.
  4. Verification: Use a spirit level across the joists to ensure the entire frame is flat.
  5. Maintenance: Periodically check for movement or settling after the first season of use, especially in areas with significant temperature fluctuations. Keep the area around the pedestals free from excessive leaf litter or moisture-trapping debris to maintain longevity.
