Treatments and finishes for hydraulically pressed tiles and terrazzo
Every piece leaves the factory ready for use: anti-slip surface, mineral finish or waterproofing applied during production. Safety and protection without compromising on the design we've handcrafted since 1975.
Torra's treatments and finishes are factory-applied processes that prepare each hydraulic or terrazzo tile for its final use: TorraStone® adds an anti-slip surface for outdoor and wet areas, Concrete Diamond incorporates aggregate and natural stone with a mineral look, and factory waterproofing protects the material against stains and moisture from day one.
TorraStone®: the hydraulic, non-slip tile
A mechanical treatment applied at the factory that gives surfaces the grip required for terraces, pool areas, showers and hospitality., without altering the drawing or the colour of the tile. It's not a resin or a coating: it's a finish of the piece itself, and it requires no specific subsequent maintenance.
Available in all our Hydraulic tile collections. We were the first company to develop a certified anti-slip hydraulic tile.

Concrete Diamond: Mineral finish with natural stone
We lay the decorative layer of the tile with arid, selected natural stone and mother of pearl; The final polish reveals a mineral-like finish, with the depth of granite and the lively speckle of classic terrazzo, which is never the same between two pieces.
Same cement base, same 18 mm thickness, customisable on a pallet of Over 100 colours.
Discover the Concrete Diamond finishWaterproofing of hydraulic tiles at the factory
Hydraulic tiles are a porous material that are traditionally sealed on-site, after installation: an extra step, with drying times and room for error. Our factory waterproofing applies that protection during production, under controlled conditionsThe material arrives on site already protected against stains, moisture, and external agents.
Protection from day one
Also during the work itself, which is the phase with the highest risk of stains for a freshly laid floor.
Less work in installation
The material arrives ready: with no pre-sealing or drying times added to the construction schedule.
Uniform application
Piece by piece and in factory-new condition, not applied with a brush onto flooring that has already been laid.
What treatment does your project need?
Each use requires a different preparation. This is our starting recommendation; we'll fine-tune it with you, project by project.
| Usage | Recommended treatment | Why |
|---|---|---|
| Bathroom and shower | TorraStone® Waterproofing | Non-slip surface in wet areas and protection against water and soaps. |
| Kitchen | Factory waterproofing | The priority is stain resistance: oil, wine, household acids. |
| Exterior: terrace, patio, swimming pool | TorraStone® | Safety when walking on wet surfaces and weather resistance. |
| Hospitality and contract | TorraStone® Waterproofing | High traffic, frequent cleaning, and regulatory demands. |
| Heritage and restoration | Technical query | Every original soil requires its own diagnosis before treatment. |
| Author's project · terrazzo effect | Diamond Concrete | Mineral finish with natural aggregate and stone, customisable in over 100 colours. |
How we work: from project to processed piece
Could you tell us about the project?
Use, stay, interior or exterior, intended use. That's enough to get started.
We recommend treatment and finishing.
And if you want, we'll send you Free samples to decide with the piece in hand.
We apply it at the factory
Each piece is treated during production in Sant Quintí de Mediona, under controlled conditions.
We deliver ready to install
The material arrives on-site ready for use, with no outstanding steps.
Post-installation maintenance
A factory-treated floor requires little maintenance: cleaning with pH-neutral soap and, depending on use, reapplying protection over time.
