Product Information

Full details

The Ecoscape Composite Decking Fixed Pedestal (ECO4126QD) is designed for professional landscapers and DIY deck builders looking to create a stable, long-lasting foundation for composite joist systems. By elevating the substructure, these pedestals prevent direct contact with the ground, significantly reducing moisture buildup and improving drainage; however, users must ensure the surface below is level and structurally sound to avoid uneven decking surfaces.

FAQs

Can I use these pedestals on grass?

No, these are intended for solid, non-compressible surfaces like concrete, paved areas, or properly compacted substrates.

What is the maximum height these pedestals reach?

The pedestal is adjustable between 70mm and 126mm.

Are these suitable for residential decking?

Yes, they are highly suitable for both residential and light commercial composite decking substructures.

Do I need to fix the pedestals to the ground?

Usually, the weight of the deck and joist system provides enough downward pressure to keep them in place, but you may anchor them depending on local building codes.

What happens if my deck needs to be higher than 126mm?

You would need to use a different size pedestal or a stackable riser system if available; these specific pedestals are limited to the 70mm-126mm range.

Does the material rot?

The pedestals are designed to be weather and rot-resistant, making them ideal for long-term outdoor use.

Troubleshooting

The decking feels 'bouncy' or unstable.

Check that the pedestals are properly spaced according to the joist load requirements and ensure the base is not sinking into the ground.

Difficulty achieving a perfectly level deck surface.

Verify that all pedestals are set to the correct height and that the underlying surface is not causing uneven shifting.

Pros and Cons

Pros

  • Significantly extends the lifespan of decking joists by keeping them off the ground
  • Provides a stable and level surface on uneven ground or concrete slabs
  • Highly durable construction suitable for long-term outdoor exposure
  • Promotes healthy air circulation and water drainage under the deck

Cons

  • Requires careful initial measuring to ensure the total deck height is consistent
  • Not intended for use on soft, loose soil without a compacted base or concrete pads
  • Specific height range of 70mm-126mm may not suit every project elevation

Setup, Compatibility & Care

  1. Surface Prep: Ensure the area where pedestals will sit is firm and level. If using on soil, install a solid concrete slab or stable pad first.
  2. Spacing: Follow the manufacturer's load-bearing guidelines for joist span spacing to determine how many pedestals are required per linear meter.
  3. Adjustment: Rotate the threaded head to reach the desired height between 70mm and 126mm.
  4. Placement: Lay out the pedestals, position the joists on top, and verify the level of the entire structure using a spirit level before securing the decking boards.
  5. Maintenance: Periodically check that no debris is blocking the underside drainage channels around the pedestal base to maintain clear airflow.
