What is large-format technical stone?

Technical stone is a term that defines an industrial product ideal for construction and architectural uses. It is the result of a finely formulated combination of natural raw materials, including clays with different mineral compositions, and organic compounds, to provide optimal mechanical and rheological properties.

The slabs are fired for several hours in the kiln at temperatures reaching 1,200 degrees to achieve the fusion of the components. This is after being compacted with the latest technology, applying 30,000 tons of pressure without any mould, which will ensure uniform tension in each slab.

The result is a dense, durable and versatile material with the same properties as natural stone, but many additional benefits.


Coverlam was born in response to the growing market need for large-format technical stones without sacrificing high resistance and durability properties.
