Description

The Technical Center for Natural Building Materials (CTMNC) has developed a reputation in Europe for promoting innovative techniques and for improving the quality of building materials for sixty years.

CTMNC has expertise in the characterisation, manufacturing and use of fired clay, unfired clay and natural stone as building materials and in their combination with other building materials.

CTMNC has 60 highly-skilled engineers and technicians spread over 3 geographical sites (Clamart, Limoges and Paris) that can rely on high-performance equipment :

  • a laboratory for testing materials, products and works
  • a laboratory dedicated to research and development on ceramic behaviour (characterisation, processes and surface covering)

Our vocation is to meet the needs of many players in the fields of materials, construction processes, building and roads. We also support professionals wishing to develop technological innovations.

Our interlocutors are industrialists, project managers, project owners, manufacturers or representatives of local authorities.

CTMNC belongs to several french and european networks :
