Cement tile finishes

Concret Diamond

Name: Concret Diamond
Brand: Mosaics Torra

Terrazzo is born from the cement tile. Concret Diamond inlays natural aggregate and snail shell into the surface of our encaustic cement tile, achieving the grain, depth and feel of classic terrazzo —handmade, piece by piece, as we have since 1975.

The finish

What the Concret Diamond finish is

Concret Diamond is not an imitation or a printed vinyl: it is a real cement tile, with the same cement base and the same 18 mm thickness which characterise Mosaics Torra, to which we add a noble layer sown with mineral aggregates and fragments of snail mother-of-pearl.

The result is a piece that retains the soul of the hydraulic mosaic – its density, its resistance, its Mediterranean character – but with the visual interpretation of terrazzo: a lively speckled pattern that changes with the light and never repeats itself exactly the same between two tiles. It is, quite literally, two traditions of artisanal paving fused into a single piece.

The process

How it's made: aggregate and snail shell

Each Concret Diamond tile is built up in layers, following the traditional cement-tile method:

Aggregate selection
We select hand-calibrated mineral grains and snail shell fragments. The size and proportion of the aggregate determine the size of the speckling: from fine and homogeneous to a more generous and expressive sowing.
The noble layer
First, the coloured and aggregate layer – which will be the visible part – is placed in the mould, by mixing pigmented cement with natural aggregates.
Hydraulic press
The tile is pressed at high pressure, without firing. It is the pressure – not the kiln – that gives encaustic tiles their legendary density and durability.
Cured and polished
After setting, the surface is polished to expose the embedded aggregate and snail shell, revealing the terrazzo effect. This final polish is what brings out each inlay.

The whole process is handcrafted, piece by piece. No two Concret Diamond tiles are alike: it is the signature of the handmade.

Two traditions, one piece

From hydraulic mosaic to terrazzo, in a single piece

For decades, terrazzo and the cement tile have been two separate paths of artisan flooring. Concret Diamond brings them together: part of our cement tile of 20x20x1.8 cm and gives it the terrazzo surface, without sacrificing the colour customisation or the agile delivery that characterise our stock.

For architects and interior designers, this opens up an unusual possibility: specifying the contemporary look of terrazzo with the traceability, thickness, and backing of a hydraulic manufacturer with verifiable references – from Casa Batlló to international hotel projects.

Where does it work

Applications and environments

Concret Diamond is designed for those who want terrazzo without giving up the cement-tile craft:

Residential interior designKitchens, bathrooms and living rooms that call for a textured surface with its own light.
Hospitality and retailHigh-traffic floors that require both character and durability in equal measure.
Author's projectsWhen the floor has to be the star and tell a story.

To your project

Colours and personalisation

The Concret Diamond speckle can be tuned to your project: background colour, size and density of the aggregate, and the shade of the snail shell. We work from our palette of over 100 colours and produce bespoke combinations for specific requirements.

Are you looking for a concrete grey with a subtle pearlescent sheen, or a warm base with plenty of aggregate? We’ll work it out with you at Design your cement tile.
