OUR certifications

Our innovative solutions validated by construction experts

certification CSTB Materrup

Whether it's the mechanical strength of the produced concrete, their workability, resistance to cold or freezing, or durability, all the benefits offered by our technologies have been thoroughly tested. 

We conduct our tests in close collaboration with our certifying partners, construction partners, and manufacturing partners – the brands that integrate our technologies into their products.

One objective: Ensure that not only MATERRUP cements meet our high-quality standards, but also the concrete products manufactured by these brands.

An official technical evaluation validated by the CSTB (French Technical Center for Building).

In July 2022, the Scientific and Technical Center for Building (CSTB) awarded the Technical Evaluation of Products and Materials (ETPM) certification for our uncalcined clay cement

This ETPM serves as the identity card for Materrup MCC1® clay cement, validating its structural characteristics. It enables us to deploy the Crosslinked Clay Cement® technology with our ready-mix concrete partners, precasters, and builders.

A strategic agreement with CSTB to accelerate Materrup technology

On July 28, 2023, Etienne CREPON, President of CSTB, and Mathieu Neuville, CEO of MATERRUP, sealed a binding strategic partnership agreement for the coming years to accelerate the deployment of the CCC© technology based on uncalcined clay, through an evaluation process tailored by CSTB.

Having worked together for over 4 years, this alliance is part of a shared commitment to the international influence of French scientific and technical expertise.

By incorporating circular economy principles and the preservation of natural resources into its uncalcined clay cement, MATERRUP already provides a mature and certified solution for numerous applications, both structural and non-structural.
