FAQs

Can these pedestals be used on soil?

They should only be used on a firm, consolidated surface. If using on soil, you must install a concrete pad or paving slab beneath each pedestal to prevent sinking.

How much weight can one pedestal support?

These pedestals are engineered for standard residential decking loads; always refer to your joist span plan to ensure the load is distributed across multiple units.

Do I need to fix the pedestal to the ground?

In most deck applications, the weight of the deck structure is sufficient to hold the pedestals in place, but local building codes may vary.

Are these pedestals compatible with all joists?

They are designed to accommodate standard composite or timber joists, but ensure your joist width fits the cradle dimensions before installation.

What is the primary material?

They are made from high-density, weather-resistant plastic designed for outdoor structural support.

Troubleshooting

Deck feels bouncy or uneven after installation

Check that all pedestals are locked at the correct height and that the joists are securely resting in the cradles.

Difficulty turning the adjustment collar

Ensure no grit or debris is stuck in the threads and verify that the weight of the joist is not resting heavily on the collar during adjustment.

Pros and Cons

Pros

  • High degree of vertical precision for leveling
  • Reduces the need for complex timber frame work
  • Elevates joists to prevent direct contact with moisture
  • Suitable for a wide range of outdoor decking applications

Cons

  • Requires a solid, non-yielding base for maximum stability
  • Not intended for use on soft soil or grass without proper foundation prep
  • Specific height range requires verifying site levels before purchase

Setup, Compatibility & Care

To install, ensure your surface is clean and level. Place the pedestals according to your joist span recommendations, typically spaced 400mm to 500mm apart. Once placed, lay your joists into the pedestal cradles. Adjust the height by twisting the collar until your spirit level indicates a flat plane. For care, ensure the area beneath the deck remains free from debris that could trap moisture. Periodically inspect the pedestal stability after the first few seasons, particularly if the ground beneath has settled due to heavy rainfall or extreme temperature changes.
