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:
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.

Pedestal supports are innovative systems for terrace and floor construction. They consist of a base, a height-adjustable thread, and a slip-resistant head. They allow tiles, ceramic slabs, or concrete pavers to be laid cleanly and level without using mortar – even on uneven ground. By adjusting the height precisely, pedestal supports ensure stability, perfect alignment, and a long-lasting, visually appealing terrace surface.
Self-leveling pedestal supports are especially suitable for sloped or uneven areas as they automatically compensate for unevenness. This creates a stable surface and prevents tension or breakage in the tiles. However, on flat and even surfaces, fixed pedestal supports are often a cost-effective and practical alternative. The best choice depends on the condition of the substrate and the desired installation comfort.
Pedestal supports are ideal for renovation and refurbishment projects. Old balconies or terraces can be upgraded without extensive preparatory work. Thanks to the dry, mortar-free installation, tiles or slabs can be lifted, replaced, or re-leveled at any time. The system also provides space for cables, drainage, or pipe installations – making it perfect for modern and flexible outdoor upgrades.
Adjusting pedestal supports is quick and straightforward. Using a standard flathead screwdriver or pedestal adjustment tool, the thread is rotated to the desired height. This allows millimeter-accurate leveling of slabs, even on surfaces with significant height variations. This precision is one of the biggest advantages of modern pedestal systems.
Compared to traditional mortar installation, pedestal supports offer many benefits: faster installation, a clean working process, and a raised substructure that allows for cable routing, drainage, and ventilation. They provide long-term height stability, frost resistance, and easy access for maintenance or tile replacement. Pedestal support systems are a modern, sustainable, and flexible solution for terrace construction.
