Microbial Induced Carbonate Precipitation: Meet the Bacteria behind the Mimmik Tile

The process is called Microbial Induced Carbonate Precipitation: bacteria trigger the formation of calcium carbonate, the same mineral that builds coral reefs, shells, and limestone cliffs.
MICP itself isn’t new. Researchers and engineers have studied and applied it for years – to strengthen soil, repair cracks in concrete, and stabilise foundations. What’s new is bringing that same biological process into a finished architectural material. To create a Mimmik Tile, sand, aggregate, and living bacteria are brought together and fed with nutrients. They begin producing calcium carbonate (the same mineral that makes a coral reef dense and durable), and after roughly 40 hours, a solid crystalline calcium carbonate matrix holds the material together.
As the biological process continues, new mineral bonds develop between particles, and the structure begins to strengthen from within.
As more bonds form, the biocementation grows denser and the structure becomes continuous, encapsulating each grain of sand and aggregate from the inside out.
The result carries an A+ environmental rating, and because it’s grown rather than fired, its carbon footprint sits far below conventional ceramic or natural stone.
Now we have a beautiful tile grown by bacteria, ready to be walked on. And admired, of course! Click here for all specs, technical documentation, price indication, our digital design tool and physical sample request form.
