LERM’s expertise is based on the fundamental knowledge of hydraulic binders. This knowledge progressively extended to concrete and its pathologies in the sector of building and civil engineering infrastructures. Then, it developed to stone and its special features related to ageing in the field of historic monuments. Our knowledge of binders and concrete naturally led us to develop a new point: recycling waste or industrial by-products in the sector of building materials.

Member of the setec group

The LERM is part of the French independent engineering group setec.100% of the shares owns to the managers and majors engineers of the group setec.
The group is totally independent regarding to others companies, banks and industrial groups.

Our services like our experience leans on a bubbling synergy of group, born from the major public infrastructure conception, in order to guarantee
the quality of our operations in every sequence of the building process. To know more about the setec group. http://www.setec.fr
