What is econic clay for
Wall Coverings and Floors?

Natural raw materials such as natural soil, quartz, fine ore, cinerite, and fly ash are used as raw materials. They are classified into four groups by different colours. By grinding the four groups of materials respectively and combining the materials of same color with an active agent, the materials are tranformed to a powder with a high activity: econic clay.

econic clay is superior

Nature and design are the two most important terms in the cardamia vocabulary. econic clay combines ecological and economic advantages with iconic design. Its material properties will make it the number one sustainable building material in interior design.


cardamia is flexible, bendable, and can be rolled up to a 60-degree angle, with a maximum depth of 6 mm for each slab. Also, you can easily handle it to create astonishing and organic interiors without destroying the material.

Large Size

cardamia panels can be produced in various sizes from 500×500 mm or 600×300 mm up to 2700×1200 mm depending on your needs. This gives you ultimate design freedom.


cardamia is extremely light. A squaremeter is about 4-5 kg. Therefore, transportation and handling are extremely easy.


Depth can be chosen freely up to the maximum depth of 6 mm. At high depth, patterns can be integrated in the material to model inspiring 3D structures.

But wait, there is more…

Additional to these four main properties, cardamia – econic clay offers a lot more benefits in its application and maintenance:

  • excellent plasticity

    The material is versatile and highly functional. cardamia products can be installed almost anywhere.

  • fireproof – and more

    cardamia – econic clay products are durable, fireproof, impact resistant, and crackproof. They are also freeze-thaw resistant, breathable, and flexible. And: There is no long-time color fading.

  • health-beneficial

    cardamia – econic clay is completely made of natural (and recyclable) raw materials. Therefore, it is nontoxic and, due to its water-absorption quality, it creates a good indoor climate and is overall health-beneficial.

  • expandable material qualities

    Combined with a polymer, econic clay is developed into various kinds of hybrids with additional material properties, like an excellent weather adaptation ability with a guaranteed lifespan of at least 30 years.

Made for
your project

cardamia – econic clay combines ecological and economic advantages with iconic design. It is a natural material that opens new perspectives for urban living through properties unique among interior design materials.

Made for iconic design
  • is natural and looks natural
  • its design and form can be easily individualized and customized with specific patterns
  • its depth allows the creation of designs that cannot be produced with ordinary panels
Made for sustainability
  • is completely recyclable due to it consisting completely of natural raw materials
  • low energy requirements and no pollution in production also contribute to the eco-friendly properties
  • consists of clay: clay mining does not destroy nature
  • is produced under fair working conditions
  • generates a healthy and pleasant indoor climate, for example it absorbs and dispenses humidity
  • is certified with certifications like Greenguard Gold, the Singapore Green Label, and many more (for complete list, see footer)
Made for economic building
  • is easy and fast to process with natural glue
  • is bendable and extremely light, so handling is easy during delivery, storage, processing, and maintenance
  • is non-breakable due to its flexibility

How to use cardamia

  • receive cardamia, which arrives either rolled up or in form of plates, at your convenience

  • tailor it for its specific purpose on site

  • apply adhesive on the back

  • attach the tiles according to your plans

  • if necessary, join the tiles with sealant

  • scrape off overflow sealant or adhesive, do not wet wipe

  • dust with a dry sponge – and enjoy your result

How we create

100% sustainable and 100% smart production: In modified clay technology, a mix of natural raw materials such as soil, sand, stone powder, and ash undergo a spray-mixing process converting them into modified inorganic materials encapsulated with active surface coating. The resulting modified material is cardamia – econic clay. It can be formed in the same way as plastic into any shape and profile, such as thin sheets, boards, or blocks, through manipulation of heating curves and photochemical isomerism technique.

cardamia – econic clay allows for interior design with a carbon footprint which is reduced by 80%, compared to traditional decorative materials. It can be recycled and reused infinitely. It opens a whole new world of application possibilities: substituting concrete to build roads; replacing plastic, resin, cement, and wood to produce flatted board, customized shapes, rolls or even art display. Phomi, as the inventor of cardamia, welcomes talents from all sectors to provide application and design ideas for econic clay – for mutual benefits and to save the environment.

We cleared our minds and combined an ancient material, the knowledge of craftmanship with cutting edge technology to create cardamia, the new freedom in sustainable building.”
