Product Information

Full details

The Ecoscape Adjustable Pedestal (ECO171139KD) is engineered for professional deck installers and serious DIY enthusiasts who require a stable, level substructure for their composite decking projects. By providing precise height support between 1199mm and 1309mm, these pedestals eliminate the need for laborious timber shimming or site leveling; however, they require a solid, stable substrate like concrete or compacted gravel to perform as intended.

FAQs

What is the minimum height these pedestals provide?

The minimum height for this specific model is 1199mm.

Can I use these on grass?

No, pedestals must be installed on a stable, solid substrate like concrete or a paving slab to prevent sinking or shifting.

How many pedestals do I need?

The number of pedestals depends on your specific joist span requirements and the total area of your deck; consult your deck design plan for spacing guidelines.

Are these pedestals resistant to moisture?

Yes, they are designed for outdoor use and are constructed to resist decay and moisture-related damage common in subframe environments.

Can I adjust them after the deck is built?

While minor adjustments may be possible, it is significantly more difficult to adjust once the deck boards are installed; aim for perfect leveling during the frame stage.

Troubleshooting

Pedestal feels unstable

Ensure the base is on a solid, level surface and that the joist is properly seated within the pedestal head.

Unable to turn the adjustment collar

Clean any grit or debris from the threads and ensure the weight of the joist is not resting entirely on the threads while attempting to adjust.

Joist is wobbling

Check that the joist is correctly sized for the pedestal head and use mechanical fasteners if the pedestal manufacturer specifies them.

Pros and Cons

Pros

  • Significant time savings compared to traditional shimming methods
  • Highly adjustable range for complex ground gradients
  • Robust weight-bearing capacity for composite materials
  • Promotes proper drainage by keeping joists off the ground

Cons

  • Requires a firm, non-shifting base for optimal performance
  • Large height range may require additional bracing if extended to maximum length
  • Not suitable for direct placement on soft soil or grass

Setup, Compatibility & Care

Before installation, ensure your ground is compacted and stable. Place each pedestal on a flat surface, such as a concrete pad or a paver, to distribute the load effectively. Position your joists into the pedestal heads and check for levelness using a spirit level. Adjust the height as necessary by turning the pedestal nut until the bubble is centered. For long-term maintenance, occasionally inspect the joist connection points to ensure they remain secure. Ensure that no debris or mud buildup prevents the adjustment collar from turning if future maintenance or leveling is required.
