Building material = raw material

Clay is a naturally occurring raw material available in almost unlimited quantities. No dedicated extraction pits are required for the clay used by ClayTec: among other sources, it occurs as an overburden layer during sand and gravel extraction and is used by us as a secondary raw material for the production of clay building materials. The origin, composition, and environmental impacts of the raw materials used are documented in our externally verified Environmental Product Declarations (EPDs) in accordance with DIN EN 15804 and DIN EN ISO 14025, available in our Download section.

The building material clay

Easy procurement

A significant proportion of soils worldwide contain clay, making it an abundantly available natural raw material. At ClayTec, no dedicated pits are excavated to source our clay. The excavated clay we use is generated in other extraction activities and, without our use, would otherwise be disposed of.

Short ways

The clay and the majority of the other raw materials used in our products are sourced from the regions surrounding our respective production sites. Transport distances are often only a few kilometers. This supports resilient supply chains while reducing the energy required for transportation.

The building material clay

Simple supply chains

Our raw material can be used directly as a building material. Many of our products consist of only a few components, primarily or entirely clay, sand, and natural additives such as straw. Production is based on straightforward mixing processes and does not require chemical additives. This simplicity also contributes to reliable supply, including during challenging periods such as the COVID-19 pandemic or geopolitical crises.
