Pedestal supports for floor slab installation have become indispensable in modern craftsmanship. They enable fast, precise, and mortar-free installation of terrace slabs, floor coverings, or paving stones — especially on challenging substrates. For tilers and tradespeople, pedestal supports offer real added value by easing work and ensuring a durable, high-quality result.
Installing slabs on uneven or sloping ground often presents a major challenge. Irregularities can lead to unstable surfaces that cause both aesthetic and functional problems. Moreover, laying slabs on gradients or over pipes and cables complicates the work considerably.
This is where pedestal supports come in: they reliably compensate for uneven ground, provide a stable base, and allow exact levelling. This reduces installation errors, avoids rework, and significantly extends the lifespan of the laid coverings.
Especially helpful are self-leveling pedestal supports, which automatically adjust to varying ground slopes. This creates a consistently even surface without manual adjustment at every support point. This saves time, minimises errors, and sustainably improves installation quality.
A pedestal support consists of three main parts: the base, the height-adjustable threaded spindle, and the top part. The top is usually equipped with a non-slip rubber coating and a joint spacer cross, improving slab hold and reducing movement.
The adjustable threaded spindle enables precise ground levelling – easily done with a standard flat-head screwdriver. Unevenness can be compensated quickly and efficiently, significantly reducing installation time.
The base distributes the weight of the slabs evenly onto the substrate and provides a stable, durable foundation.
Pedestal supports are particularly suitable for:
Terrace and balcony flooring
Outdoor floor slabs
Areas with cables or pipes running beneath slabs
Surfaces with gradients where water drainage must be ensured
The major advantage of pedestal technology lies in mortar-free installation: time-consuming screeding or consolidation is unnecessary. Pipes and cables remain accessible for future maintenance or repairs.
Tilers and tradespeople benefit primarily from significant work facilitation and time savings. Precise height adjustment enables fast installation with consistently high quality and stability. The result is a level, durable surface meeting demanding customer expectations.
Additionally, pedestal supports improve planning and execution flexibility, allowing even difficult ground conditions and complex terrains to be managed easily.

What are pedestal supports and how do they work?
Pedestal supports are height-adjustable feet that support floor slabs evenly on uneven substrates. They consist of a base, threaded spindle, and top part with a non-slip surface.
Are self-leveling pedestal supports always the best choice?
They are ideal for uneven and sloping surfaces as they adjust automatically. For very even substrates, fixed models may also be suitable.
Can pedestal supports be used for renovations?
Yes, most pedestal supports are suitable for retrofitting and allow easy, mortar-free installation.
How are pedestal supports adjusted?
The threaded spindle can be quickly and precisely turned to the desired height using a standard flat-head screwdriver.
What advantages do pedestal supports offer compared to traditional installation?
They save time, improve installation quality, allow easy installation of cables, and provide a durable, flexible solution.
