Product Information

Full details

The Ecoscape Composite Decking Fixed Pedestal is designed for DIY enthusiasts and professional contractors seeking a stable, level substructure for outdoor flooring projects. By providing a secure foundation for joists, these pedestals ensure proper drainage and airflow beneath your deck, significantly increasing its lifespan. While they offer exceptional structural support, they are specifically intended for a narrow height range of 21mm to 30mm, meaning they are not suitable for projects requiring significant elevation changes or major slope correction.

FAQs

Can these pedestals be used on soft soil?

No, they must be installed on a solid, stable surface such as concrete, paving slabs, or a compacted aggregate base.

How many pedestals do I need?

The number of pedestals depends on your joist spacing and the span requirements of your specific decking material. Refer to the decking manufacturer's instructions for span guidelines.

Are these adjustable while the joist is in place?

Yes, the design allows for fine-tuning the height even after initial placement, provided the weight of the joists is relieved slightly.

Can I use these for timber joists?

Yes, these pedestals are compatible with timber joists as well as composite joists, provided they are sized correctly for the pedestal head.

What is the primary benefit of using pedestals?

The primary benefit is protection against moisture damage for your joists and the ability to achieve a perfectly level deck surface over slightly uneven ground.

Troubleshooting

Joists feel unstable or wobbly

Ensure the pedestal is fully tightened and the base is resting flat on a firm, level sub-surface.

Difficulty achieving the exact desired height

Verify that the total stack height, including the joist thickness, falls within the 21mm-30mm range; adjust the pedestal rotation slowly.

Pros and Cons

Pros

  • Ensures a perfectly level deck surface
  • Increases the lifespan of joists by preventing water contact
  • Easy to install for professional or DIY results
  • Sturdy construction for long-term reliability

Cons

  • Limited to a specific height range of 21mm-30mm
  • Not suitable for extremely uneven surfaces needing high adjustment
  • Requires careful spacing calculations before installation

Setup, Compatibility & Care

To install, ensure your sub-base is clean and clear of debris. Lay out your joists first to determine the required spacing, then place the pedestals underneath. Use a spirit level frequently during placement to verify that the joist tops are perfectly flat. Regarding compatibility, these pedestals work effectively with standard composite decking joists. Maintenance is minimal; ensure that the area beneath the pedestals remains clear of organic debris, such as leaves or dirt, to maintain proper water flow. Periodically inspect the deck surface for any signs of movement or sagging, and adjust the pedestal height if necessary.
