Concrete Pedestals for Raised Access Flooring - dry, accessible installation
Concrete pedestals for raised flooring: a floor you can lift back up
When paving is fully bonded down, any fault underneath means breaking it up and redoing half the terrace. These pedestals let you lay the paving dry, resting on concrete pieces, so the floor stays accessible and a future repair just means lifting a few slabs.
✅ Key advantages
Accessible flooring: lift the pieces you need and reach whatever is underneath, with no building work.
Dry installation: no mortar or curing time, it can be walked on right away.
High load capacity: they take heavy loads, mainly limited by the strength of the slab itself.
Five sizes: different heights and cross-sections to handle various levels and thicknesses.
🏗️ Recommended applications
Terraces and roof decks with services beneath the paving.
Accessible and inverted roofs.
Paving over waterproofing membranes.
Surfaces where future repairs are anticipated.

🧰 Installation
Check that the substrate is clean and that any waterproofing is intact.
Mark out the grid to match the slab format: one pedestal at each corner of the piece.
Place the pedestals and check that all of them make full contact.
Adjust the height by combining sizes until the plane is level.
Bed the slabs, checking that none rocks on only three supports.
Finish off the perimeter so the edge pieces can't tip.
📦 Available formats

12 × 5 cm.

Sold by unit or by pallet.
💡 Professional tip: the classic fault with raised flooring is a slab resting on only three pedestals that rocks underfoot: it makes noise, chips at the corner and eventually breaks. Before calling the job finished, step on the edge of every single slab, one by one. Any that rock get shimmed — never left for later.

No; la colocación es en seco y se pisa de inmediato.
¿Qué carga aguantan?
Cargas altas, limitadas principalmente por la resistencia de la propia losa de terrazo.
¿Qué tamaños hay?
Dos de 16x6 cm, uno de 12x5 cm y dos circulares de Ø 12x4 y Ø 12x3 cm.
¿Cuántos soportes necesito por losa?
Uno en cada esquina de pieza, según la retícula del formato elegido.
¿Cuántas unidades trae el palet?
504 en 16x6 cm, 768 en 12x5 cm, 960 en Ø 12x4 cm y 1.152 en Ø 12x3 cm.
¿Se pueden combinar tamaños?
Sí, es lo habitual para ajustar la altura y nivelar el plano.
¿Qué hago si una losa baila?
