What are adjustable height pedestal systems — podiums and balconies?
Adjustable height pedestal systems are polypropylene support components used to create a raised, level paved surface over a waterproofing membrane on balconies, terraces, podium slabs, and roof decks. Each pedestal supports the corner or edge of a paver or tile at an adjustable height above the membrane surface — the paver rests on the pedestal head rather than being bedded in adhesive or mortar. The gap between adjacent pavers allows surface water to drain freely through the joints and discharge across the membrane below, which then conveys water to the drainage outlets. The pedestals protect the membrane from direct traffic loads by distributing paver loads through the pedestal base rather than imposing concentrated point loads on the membrane surface.
In Class 2 strata remediation on podium slabs and roof decks, pedestal systems are specified where the existing slab requires a new waterproofing membrane and the finished paver level must be set at a fixed height — typically at the threshold level of doorways or at an agreed finished floor level above the membrane surface. Pedestal systems allow the paver height to be adjusted during installation to achieve a level finished surface regardless of minor variation in the membrane or protection board surface below. They also allow access to the membrane and any services below by simply lifting the pavers off the pedestals — without breaking out adhesive or mortar.
Pedestal height range is the critical specification decision. Heights from as low as 12mm (for thin-set paver applications on essentially flat substrates) to over 1000mm (for deep build-up requirements on podium slabs above services or insulation) are available. The required height is determined by the membrane surface level, the required finished paver level, the thickness of any insulation or protection board below the paver, and the paver thickness itself.

Keksia NM and PR series adjustable pedestal systems — PR series self-levelling head accommodates slopes up to 5% — bi-material anti-noise head reduces sound impact up to 25dB — Star.T series from 10mm minimum height — available through TradieCart and keksia.com.au — 70 years Italian engineering (Eterno Ivica)
System Description
Keksia is the Australian retail brand for Eterno Ivica, an Italian pedestal manufacturer with 70 years of engineering history. The Keksia range covers three primary series: NM series (standard fixed substrate for flat surfaces), PR series (self-levelling head for slopes up to 5%), and Star.T (ultra-low 10mm minimum height for renovation projects with minimal clearance). All Keksia pedestals feature the patented bi-material anti-noise head — claimed to reduce sound impact level by up to 25dB — the head incorporates two materials of different density that absorb foot traffic impact and reduce noise transmission to the structure below. This is a differentiating feature relevant on podium slabs above occupied apartments where paver foot traffic noise is a resident amenity concern.
TradieCart (Melbourne-based, online delivery) stocks the full Keksia range and provides detailed height range guidance for each series. The PR series self-levelling head is particularly suited to podium and roof deck applications where the membrane surface has a drainage fall built in — the pedestal head swivels to maintain a level paver surface over the sloping substrate without adjustment.
Keksia also offers windproof heads with T-clips and L-clips for wind-exposed rooftop and coastal applications, and Wood Deck and Al Joist head options for timber and composite decking applications over pedestals.
Technical Properties
- NM series: flat substrate — multiple height ranges from NM0 (15–25mm) through NM5 (175–270mm) and beyond
- PR series: self-levelling head — accommodates substrate slopes up to 5% — suitable for drainage-graded membranes

WIND UPLIFT RETENTION MUST BE SPECIFIED FOR EXPOSED ROOFTOP AND COASTAL LOCATIONS — STANDARD PEDESTALS RELY ON PAVER DEAD WEIGHT ONLY
Standard adjustable height pedestals support pavers by gravity — the paver rests on the pedestal head by its own weight and is not mechanically fixed. On exposed roof decks, elevated terraces, and coastal balconies where wind pressure beneath the paved surface can exceed the paver dead weight, this is a serious safety risk — pavers can be lifted and displaced by wind, creating a fall and projectile hazard for occupants and adjacent areas. Before specifying standard gravity-retained pedestal paving on any exposed or elevated location, confirm with the building engineer whether wind uplift retention is required. Where required, specify windproof pedestal heads with mechanical clips (Buzon fixing accessories, Elmich Versijack CP, Keksia windproof T-clips and L-clips) or adhesive paver retention systems. Do not assume that paver weight alone is sufficient on high-rise balconies, elevated terraces, or coastal locations.
THERE IS CURRENTLY NO AUSTRALIAN STANDARD FOR PEDESTAL PAVING — APPLY MANUFACTURER GUIDANCE AND ENGINEERING JUDGEMENT
AS/NZS 4452 governs masonry paving units but covers testing methodologies for pavers installed on a traditional solid base only — it does not address load capacity, paver span, pedestal spacing, or structural performance for pedestal-mounted paving systems. There is currently no Australian Standard that specifically governs paving installed on adjustable height pedestals. On commercial podium slabs, roof decks, and strata balconies, the pedestal spacing, paver thickness, load capacity, and structural performance must be determined by applying the pedestal manufacturer's technical guidance and, where loadings are significant or uncertain, by an engineer's assessment. Do not assume that any pedestal system is compliant with an Australian Standard for pedestal paving — no such standard currently exists.
CONFIRM MEMBRANE PROTECTION BEFORE PLACING PEDESTALS ON THE CURED MEMBRANE
Adjustable height pedestals are placed directly on or above the cured waterproofing membrane — either on the membrane surface itself or on a protection board above the membrane. The pedestal base must not damage, puncture, or abrade the membrane surface. On soft liquid-applied PU and hybrid membranes, placing pedestals directly on the membrane without a protection board can cause indentation or stress concentration at each pedestal base, potentially compromising the membrane at those points over time under repeated loading. Confirm with the membrane manufacturer whether a protection board or membrane protection mat is required between the membrane surface and the pedestal bases before placing pedestals. Refer to the Protection Boards page for compatible protection board options.
PEDESTAL PAVING PROVIDES MEMBRANE ACCESS — ADHESIVE-BEDDED TILE DOES NOT
A significant advantage of pedestal paving over adhesive-bedded tile on podium slabs and roof decks is accessibility to the membrane below. Individual pavers can be lifted off the pedestals without tools or breaking out, allowing the membrane to be inspected, flood-tested, or repaired after the paving is complete. This is particularly important on Class 2 strata podium slabs and roof decks where the membrane may need to be inspected for defects or repaired under warranty — and where breaking out and re-bedding adhesive-fixed tiles is prohibitively costly. Confirm with the building owner and strata manager whether membrane accessibility is a priority for the specific project before specifying either pedestal or adhesive-bedded paving.
