Decking & Paving Supports from 10mm to 975mm<\/span><\/span><\/h5>\n<\/div><\/div><\/div><\/div><\/div>

F.<\/span>H.Brundle’s<\/span> adjustable pedestals and supports<\/a> <\/b>give contractors, <\/span>architects<\/span> and landscapers a fast, flexible foundation for any raised deck, paving or flooring. Covering heights from 10mm (cradle) to 975mm using just four core components, our pedestal system \u2014 also known as decking risers<\/i> or decking feet<\/i> \u2014 suit porcelain tiles, timber <\/span>joists, <\/span>aluminium framing and even industrial flooring. Self-levelling heads correct slopes up to \u00b15\u00b0, anti-unscrewing safety blocks prevent movement, and a rubber-coated head reduces noise trans<\/span>mission. Whatever the substrate, this system delivers a level, professional result every time.<\/span><\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

\u2022 They allow precise height adjustment to achieve a level deck surface.<\/span>\u00a0<\/span><\/p>\n

\u2022 Improved water drainage and airflow extend the lifespan of your deck.<\/span>\u00a0<\/span><\/p>\n

\u2022 Installation is faster compared to traditional subframes.<\/span>\u00a0<\/span><\/p>\n

\u2022 They are suitable for use on roof terraces, balconies, and patios.<\/span>\u00a0<\/span><\/p>\n

\u2022 They are compatible with a range of joist materials.<\/span>\u00a0<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Cradle Head Pedestal Design<\/h4>\n

Cradle pedestal heads secure decking joists and distribute weight evenly across the base. This ensures long-term stability and durability of the deck frame.<\/span>\u00a0<\/span><\/p>\n

Decking pedestals<\/a> <\/b>are used to raise and level decking substructures, allowing decks to be installed on uneven surfaces such as terraces, balconies and roof spaces.<\/span><\/span><\/p>\n

Adjustable pedestals can support timber, aluminium and composite joist systems.<\/span><\/span><\/p>\n

Spacing depends on the decking system used, but pedestals are typically installed every 400\u2013600mm along the joists.<\/span><\/span><\/p>\n

Pedestal systems are commonly used for roof terraces because they protect roof membranes while creating a stable decking surface.<\/span><\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

Adjustable Pedestal System Installation Guide<\/h2>\n

Easy Setup, Secure Locking & Flexible Height Adjustment<\/h4>\n

Our adjustable pedestal system is designed for precision, durability, and ease of installation. Whether you’re working on decking, paving, or raised flooring, follow this step-by-step guide to achieve a secure and professional finish.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

<\/i><\/div><\/div>

Pedestal Adjustment Mechanism<\/h4>\n
    \n
  • The pedestal base features a clockwise thread for unwinding.<\/li>\n
  • All other sections operate with an anti-clockwise rotation.<\/li>\n
  • Locking sections function in the opposite direction, meaning you wind down to securely lock each component in place.<\/li>\n<\/ul>\n

    This dual-direction system ensures maximum stability and prevents accidental loosening.<\/p>\n<\/div><\/div><\/div>

    <\/div><\/div><\/div><\/div>
    <\/i><\/div><\/div>

    How to Separate the Base and Winder<\/h4>\n

    Follow these steps to safely undo and split the pedestal base:<\/p>\n

      \n
    1. Release the blue locking collar.<\/li>\n
    2. Unscrew the inner section until it is fully extended and locked.<\/li>\n
    3. Locate the internal access hole:<\/li>\n<\/ol>\n

      \u2022 Insert a pin, screwdriver, or similar tool
      \n\u2022 <\/span>Gently press to release the locking lug
      \n\u2022 <\/span>Unwind and remove the section<\/p>\n

      Tip:<\/strong> Blue adjusters may initially feel tight. Use a lever for extra torque, then continue adjusting by hand.<\/p>\n<\/div><\/div><\/div>

      <\/div><\/div><\/div><\/div>
      <\/i><\/div><\/div>

      Installing Pedestal Extenders<\/h4>\n
        \n
      • Rotate the extender into position using the black grip lugs for easier handling.<\/li>\n
      • Once the desired height is reached, tighten the blue locking collar to secure it firmly.<\/li>\n<\/ul>\n

        This allows for precise height control across uneven surfaces.<\/p>\n<\/div><\/div><\/div>

        <\/div><\/div><\/div><\/div>
        <\/i><\/div><\/div>

        Using Adjustable Support Rods<\/h4>\n

        For added stability between pedestals:<\/p>\n

          \n
        • Fit the collar to the pedestal at the midpoint of the total height.<\/li>\n
        • The collar remains free-moving and does not require locking, as rods provide support.<\/li>\n
        • Adjust rods to the required length and connect between pedestals.<\/li>\n
        • Make final adjustments and tighten securely.<\/li>\n<\/ul>\n

          This system improves load distribution and structural integrity.<\/p>\n<\/div><\/div><\/div>

          <\/div><\/div><\/div><\/div>
          <\/i><\/div><\/div>

          Installation Near Walls, Corners & Edges<\/h4>\n

          When installing pedestals against walls or edges:<\/p>\n

            \n
          • The underside of the base includes a marked square cutting guide.<\/li>\n
          • Trim the base as needed to fit tight spaces.<\/li>\n
          • Ensure reinforcement fins are cut evenly and aligned for continued strength.<\/li>\n<\/ul>\n

            Ideal for perimeter installations and fascia board applications.<\/p>\n<\/div><\/div><\/div>
