Product Information

Full details

The Ecoscape Composite Decking Adjustable Pedestal is designed for professional contractors and DIY enthusiasts who need a reliable, leveling foundation for elevated composite decking. Its primary benefit is providing a highly stable, load-bearing support system that accounts for uneven terrain or height requirements, though users should note that precise calculation of joist spacing is required to ensure long-term structural integrity.

FAQs

Can I use these pedestals on grass?

It is not recommended to place pedestals directly on grass or loose soil. You should create a solid, level, and compacted foundation, such as patio slabs or a crushed stone base, before installing the pedestals.

Are these pedestals resistant to rot?

Yes, they are manufactured from durable, synthetic materials designed to withstand moisture and outdoor elements without rotting or rusting.

How many pedestals do I need?

The number of pedestals depends on your deck size, the joist spacing, and the span capabilities of your chosen composite decking boards. Always follow the structural guidelines provided by your decking manufacturer.

Can I adjust the height after the joists are attached?

It is best practice to set your heights before fastening the joists. Adjusting them under a fully loaded and fixed deck frame is difficult and may compromise the stability of the structure.

What is the weight capacity of each pedestal?

Each pedestal is designed to handle significant load-bearing weights, but specific capacity limits should be verified against your project's total load requirements, including furniture and foot traffic.

Troubleshooting

Deck surface feels bouncy or unstable

Check that the joist spacing is within manufacturer specifications and ensure that every pedestal is locked securely at the desired height.

Difficulty rotating the adjustment collar

Clear any dirt or grit from the threads of the pedestal and ensure the load is temporarily removed from the unit while making adjustments.

Pros and Cons

Pros

  • Significantly reduces time spent leveling a deck frame
  • High adjustability range for complex site elevations
  • Provides essential airflow underneath decking to prevent moisture buildup
  • Reduces the need for permanent concrete footings in many applications

Cons

  • Requires careful calculation of weight distribution per pedestal
  • Adjusting height on large decks requires meticulous measurement
  • Not intended for use on soft, loose soil without a compacted base

Setup, Compatibility & Care

To set up, first clear the installation area and ensure the surface is firm. Begin by positioning your pedestals in rows aligned with your joist layout. Rotate the adjustment collar to fine-tune the height of each pedestal until the joists sit perfectly level using a long spirit level. Once aligned, fasten the joists to the pedestal heads using appropriate screws. Compatibility is broad, as these are designed for standard composite decking joists. For care, perform an annual inspection to ensure no pedestals have settled into the ground or loosened due to vibration or expansion; keep the area under the deck clear of debris to maintain proper drainage.
