Product Information

Full details

The Ecoscape Composite Decking Adjustable Pedestal (152mm-209mm) is designed for professional landscapers and DIY homeowners seeking a robust, level foundation for decking joists. Its primary benefit is the ability to easily compensate for uneven terrain or slopes, ensuring a perfectly flat deck surface without complex manual shimming; however, users should note that these pedestals require a solid, stable base such as concrete or paved ground to function effectively.

FAQs

Can I use these on grass?

No, these pedestals require a firm, level, and stable surface such as concrete, paving slabs, or a solid deck.

What is the weight capacity of each pedestal?

While capacity can vary based on distribution, these are designed to handle standard residential decking loads when used at the recommended intervals.

Do I need special tools to adjust them?

No, they are designed for manual adjustment by hand, though a spirit level is required for accuracy.

How many pedestals do I need?

The number depends on the joist span and the weight load of your chosen decking material. Follow your joist layout plan strictly.

Are they UV stable?

Yes, they are manufactured from materials designed to withstand outdoor environmental conditions.

Troubleshooting

The pedestal is wobbling or unstable.

Ensure the base is perfectly flat and clear of small rocks or debris. If the ground is uneven, consider using a thin rubber pad beneath the pedestal base.

Difficulty rotating the adjustment collar.

Check the thread for grit or construction dust. Clean the threads and apply a small amount of silicone spray to facilitate smooth movement.

Deck feels 'bouncy' after installation.

This is usually caused by excessive spacing between pedestals. Refer to your decking joist manufacturer's technical guide to decrease the support interval.

Pros and Cons

Pros

  • Significantly simplifies the process of leveling joists on uneven surfaces
  • Sturdy construction ensures long-term structural integrity
  • Wide height adjustment range suitable for various project designs
  • Easy to install compared to traditional timber sub-frames

Cons

  • Not suitable for use on soft, shifting, or uncompacted ground
  • Requires careful planning to ensure correct spacing of pedestals
  • Adjustment mechanism requires access before final joist installation

Setup, Compatibility & Care

Before installation, ensure your base is clean, solid, and capable of supporting the combined weight of the pedestals, joists, and decking. Position the pedestals according to your joist manufacturer's recommended span specifications. To adjust the height, twist the internal thread until you reach your target elevation. Once the joists are locked into the pedestal cradles, verify the level of the entire structure again. While the pedestals are weather-resistant, it is recommended to periodically inspect under the deck every few years to ensure no debris has accumulated and that no individual pedestal has shifted due to ground movement.
