Ich bin Fliesenlegermeister mit über 25 Jahren Baustellenerfahrung — und habe REVIMAG entwickelt, weil mich eine Sache auf Baustellen immer gestört hat…
REVIMAG – the invisible inspection system for tiles
Developed by the Austrian master tile layer Roland Hilberger.
From practice for practice – precise, robust and invisibly integrated.
My roots – From carpenter to master tile setter
My career as a craftsman began as a carpenter ,
an apprenticeship which I successfully completed with the journeyman's examination .
Even back then, the construction site fascinated me.
There's something special about creating something with your own hands .
Later I switched to the tiling trade – back to the construction site,
where every imperfection counts and every solution must hold.
This passion eventually led to a master craftsman's certificate as a tile layer .
which I have earned through hard work, experience and perseverance.
The problem on every construction site
Over the years, the same topic kept resurfacing:
Many inspection openings were, and still are, simply glued in place with silicone back then.
In practice , this meant that once they had to be opened, removal without damage was hardly possible.
In reality , around 90% of bathtubs on construction sites are installed without an access panel .
The common refrain is: "You'll never have to go there again anyway" – or people rely on the insurance company paying in case of damage .
But if a defect occurs, the customer is faced with a complete construction site – and if the original tiles are no longer available, the damage is twice as great.
I wanted a solution that was invisible , stable , and easy to install –
a solution that meets the demands of a professional.
Above all, it was important to me that I could install and remove tiles up to 120 x 60 cm without damaging them.
The path to the solution
2018–2020: Initial sketches, handcrafted models, practical tests.
2023-2024: Training in 3D design software
Material studies with plastics, e.g., carbon and glass fiber reinforcement ,
Magnetic geometries and screw systems.
Between 2024 and 2025, I had to deal intensively with the topic of 3D printing .
I had no prior experience – so it meant: learn, try things out, fail and start again.
It took weeks and months until a print-ready model was finally created that not only looked good but also worked in practice .
Ultimately, the idea was filed for a patent .
