Duna Tudela Sandstone Slab · Ocre: natural stone with centuries of history
Before reaching your terrace or your façade, this stone was sand. Sand from ancient rivers and deserts that, layer by layer and over millions of years, the earth pressed together in the mountains of Burgos until it became rock. That history can be read in its veining, and it is what makes no two Duna Tudela sandstone slabs alike.
Its ochre tone recalls dry earth and landscapes sculpted by the wind. Its orange veining comes from iron oxides that water left behind over millennia: each piece is a small landscape, different from the one next to it. It is the stone with the most character in the Duna family, designed above all for façades, walls and decorative panels, in 60x40x3 and 60x30x3 cm.
Sandstone is one of the stones used to build churches, bridges and houses that have stood for centuries. That's why, when you put it in your home, you are not just buying another floor or cladding: you are choosing a material that has already proven it knows how to age well.
✨ Why people fall in love with Duna Tudela sandstone
Unrepeatable beauty: each piece has its own vein and its own nuance. No space built with Duna sandstone looks like another.
Warm and alive: it changes with the light throughout the day and brings a welcoming feel that artificial materials can't achieve.
Ages with elegance: over the years it gains patina and character, like the stone of old villages, without paints or treatments.
Cool underfoot: sandstone doesn't build up as much heat as other materials, so you can walk barefoot in summer.
Beautiful and tough too: tested to 56 freeze-thaw cycles (UNE-EN 12371) and thermal shock, suitable for outdoor use in cold areas. When wet it gives 68 SRV, well above class 3 of the Spanish Technical Building Code (over 45), so it grips well around pool edges and on terraces.
Truly natural: Spanish quarry stone, saw-cut and CE marked. No resins, no imitations.
🏡 Where to use it
Cladding for façades and walls.
Fireplaces, plinths and decorative panels.

Material: natural quarry sandstone (arkose), Pinares region (Burgos).
The slabs in the shop are supplied saw-cut, but Duna sandstone is also available in other finishes: bush-hammered, honed, pick-dressed, scabbled and brushed (depending on tone).
And if your project needs something special, we make it to measure: other sizes and thicknesses, steps, wall copings, window sills, kerbs, lintels, ashlar or rubble masonry. Contact us with the dimensions, finish and quantity, and we'll prepare a no-obligation quote.
📦 Sales formats
Pack of 10 pieces: perfect for small areas, repairs or to see the stone at home before a large order. 60x40: 2.4 m² · 60x30: 1.8 m².
Full pallet: the most convenient option for building sites, palletised and strapped. Approx. 15 m² (the exact number of pieces is shown in each option).
💡 Pro tip: for floors, lay on a screed or mortar in a full bed, with no voids under the piece. Allow 5–10 % extra surface area for cuts and finishing, and mix pieces from several packs or pallets when laying to spread out the natural variations in tone. Outdoors, lay on a screed with a 1–2 % slope and use a breathable water repellent if you want to make cleaning easier.
🪨 Natural stone: each batch may vary slightly in tone and veining from the photos. It is the signature of an authentic material, not a defect.

Yes. It has been tested through 56 freeze-thaw cycles (UNE-EN 12371) and keeps its flexural strength intact. It is suitable for outdoor use in cold and mountain areas.
Is it slippery when wet?
No. When wet it scores 68 SRV in the pendulum test, well above the 45 that building codes require for class 3, the highest. It is suitable for terraces and pool edges.
Is it suitable for floors?
Tudela is intended above all for façades, walls and decorative panels, where its ochre veining shines. It also works on floors with light pedestrian traffic; for high-traffic areas we recommend the Olite tone.
