Duna Viana · Rosado Sandstone Slab: 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 into rock in the mountains of Burgos. That history can be read in its veining, and it is why no two Duna Viana sandstone slabs are alike.
Its pink tone recalls the soft rose of winter dawns over the walls of stone villages. Its pinkish beige background, with brownish veins almost like those of wood, brings a warmth that is hard to find in any other stone. It is the least porous of the Duna family and the one that best holds façade anchors (800 N).
Sandstone is one of the stones used to build churches, bridges and houses that have stood for centuries. That is why, when you bring it into 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 Duna Viana sandstone is so loved
Unrepeatable beauty: each piece has its own vein and its own nuance. No space made with Duna sandstone looks like another.
Warm and alive: it changes with the light throughout the day and brings a cozy feel that artificial materials can't match.
Ages elegantly: 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 also resistant: tested to 56 freeze-thaw cycles (UNE-EN 12371) and to thermal shock, suitable for outdoor use in cold areas. When wet it gives 74 SRV, well above class 3 of the Código Técnico (Spanish 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, including ventilated façades with anchoring.
Terraces, patios, porches and garden paths.
Pool coping and surrounds.
Restoration of rural houses and stone buildings.
Rustic interiors: living rooms, entrances and wine cellars.

Material: natural quarry sandstone (arkose), Pinares area (Burgos).
Finish: saw-cut.
Sizes: 60x40x2, 60x30x2, 60x40x3, 60x30x3, 80x40x3 and 100x50x3 cm.
Approximate weight: about 44 kg/m² at 2 cm and 66 kg/m² at 3 cm.
The slabs in the store are supplied saw-cut, but Duna sandstone is also available in other finishes: bush-hammered, honed, pick-faced, scabbled and brushed (depending on the tone).
And if your project needs something special, we make it to measure: other sizes and thicknesses, steps, coping stones, window sills, kerbs, lintels, ashlar or rubble masonry. Write to us with the dimensions, finish and quantity, and we will prepare a no-obligation quote.
📦 Sales formats
Pack of 10 pieces: perfect for small areas, repairs, or to see the stone at home before placing a large order. 60x40: 2.4 m² · 60x30: 1.8 m² · 80x40: 3.2 m² · 100x50: 5 m².
Full pallet: the most convenient option for building sites, palletized and strapped. Approx. 24 m² at 2 cm and 15 m² at 3 cm (the exact number of pieces is shown in each option).
💡 Pro tip: for outdoor floors with foot traffic choose 3 cm; the 2 cm works better on façades and walls. Allow 5–10 % extra surface 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 base 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.

Frequently Asked Questions
Does it withstand frost?
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 74 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 ventilated façades?
Yes. Viana has the highest breaking load at anchor points in the range (800 N, UNE-EN 13364) and the lowest water absorption, so it is the best choice for façades and anchored cladding.
Which thickness should I choose, 2 or 3 cm?
The 2 cm is ideal for cladding façades and walls. For outdoor floors with foot traffic we recommend 3 cm.
Are other finishes or special sizes available?
Yes. Besides the sawn cut there are bush-hammered, honed, picked, split-faced and brushed finishes, and we make other formats, steps, copings, kerbs or ashlar to measure. Write to us with dimensions, finish and quantity and we will send you a no-obligation quote.
How many m² come in each pack or pallet?
The 10-piece pack covers 60x40: 2.4 m², 60x30: 1.8 m², 80x40: 3.2 m², 100x50: 5 m². Full pallet: approx. 24 m² in 2 cm and 15 m² in 3 cm; the exact number of pieces is shown in each option.

How many slabs do I need?
Measure the area in m², add 5–10% for cuts and trimming and choose the packs or pallets that cover that total.
Do all the slabs have the same colour?
Not exactly: it is natural stone and every piece has its own veining and tone. Mix pieces from different packs or pallets when laying for an even result.
Does it need maintenance?
Very little. Just clean it with water and neutral soap. Optionally you can apply a breathable water repellent to make cleaning easier.
