Buzon PB-0-S12 Adjustable Pedestal (12-18mm) is a specialized support system for achieving precise levels in ultra-low clearance zones on rooftop terraces and balconies. Engineered from weather-proof copolymer polypropylene (CPP), this pedestal provides an industrial-strength 27.30 kN breaking load that eliminates floor bounce and supports heavy stone pavers or timber joists without risking membrane puncture.
The non-penetrative wide-base design allows Rooftop Decking & Paving Specialists to maintain structural integrity and essential sub-surface drainage in extreme environments ranging from -30°C to +80°C.
For projects involving sloped substrates up to 5%, integrate the U-PH5 slope corrector to ensure a perfectly level finish while preventing perimeter failure by adhering to the specific 420kg to 967kg breaking load limits for quarter and half-head sections.
Frequently asked questions
What is the load capacity of the PB-0-S12 pedestal?
The PB-0-S12 has a breaking load of 27.30 kN (approximately 2,730 kg) when the load is distributed across the full head at its maximum height. This provides stable support for pedestrian traffic and heavy pavers.
Can this pedestal be used on sloped surfaces?
Yes, the PB-0-S12 can accommodate slopes when used with the Buzon U-PH5 slope corrector. This accessory allows for compensation of slopes from 0% to 5% to achieve a level finished surface.
What material is the pedestal made from?
It is manufactured from copolymer polypropylene (CPP), containing approximately 80% recycled content. This material resists weathering, sea salt, algae, and various chemicals, suiting harsh Australian conditions.

Applying Buzon PB-0-S12: Professional Protocols
-
Step 1: Substrate Preparation
Verify the installation surface (e.g., concrete slab, membrane) is structurally sound, stable, and clean. Remove all dust, debris, and potential contaminants to ensure a solid footing for each pedestal.
Pro Tip: A clean site is a safe and efficient site. A quick sweep or blow-down of the area before you start saves time on adjustments later. -
Step 2: Pedestal Layout & Placement
Mark out the grid for pedestal placement according to the specifications from the paver or joist manufacturer. This is critical for ensuring proper load distribution. Place the first pedestal in a corner and work outwards.
Pro Tip: Use chalk lines to snap a grid on the substrate. This ensures your layout is perfectly square and significantly speeds up the placement process. -
Step 3: Precision Height Adjustment
Rotate the upper part of the pedestal to achieve the exact height required, from 12mm to 18mm. Use the built-in markings as a guide and confirm final levels with a laser level or string line for absolute precision across the entire area.
-
Step 4: Paver / Joist Installation
For pavers, fit the appropriate spacer tabs onto the pedestal head to ensure consistent joint spacing and alignment. Carefully lay the paver or secure the deck joist onto the pedestal heads, checking for level as you go.
Pro Tip: For minor final height tweaks after a paver is laid, use a dedicated adjustment key to rotate the pedestal base without having to lift the heavy paver off.
Product limitations
- Not for: Vehicle or machinery traffic. These pedestals are designed and tested for pedestrian traffic only.
- Not for: Unstable or non-load-bearing substrates. Install only on solid, stable, load-bearing surfaces such as concrete slabs, cured screeds, or properly constructed roofs.
Safety and handling
Personal protective equipment
Wear standard personal protective equipment (PPE) such as safety glasses and protective gloves during installation.
Load limit adherence
Always comply with specified load capacities. Ensure the planned load does not exceed the breaking load, especially at edges or corners where only partial head support occurs.
Installation guidelines
Follow installation instructions from Buzon and the surface material manufacturer to ensure a safe and durable installation.
Substrate guide
Proper substrate preparation is critical for the stability and longevity of any raised flooring system.
Concrete slabs and cement screeds
Surface prep: Ensure the surface is structurally sound, fully cured, and free of loose debris, dust, or contaminants. The wide base of the pedestal is designed for direct placement.
Primer: Not required. The weight of the finished decking or paving system typically secures the pedestals under normal pedestrian use without mechanical fixing.
Waterproof membranes
Surface prep: The membrane must be fully cured, clean, and free from sharp objects or contaminants. The PB-0-S12's smooth, wide base is designed to prevent point-loading and membrane damage.
Primer: Not required. Do not mechanically fix or glue the pedestal to the membrane, as this can cause punctures and void warranties. A protective fleece or slip sheet may be used if specified by the membrane manufacturer.
