Our innovative solutions validated by construction experts
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.

The CSTB has validated an ATEx Case A for MATERRUP walls
The scope of application of the MCC1® Walls process covers the construction of all types of reinforced or non-reinforced concrete walls for new or existing buildings (as defined in NF DTU 21 and DTU 23.1): :
• Single-family houses
• Terraced houses
• Multi-family residential buildings
• Public buildings (ERP)
• Partition walls for workshops, factories, retaining walls, etc.
The CSTB has validated an ATEX type A for MATERRUP foundations
The scope of application of the MCC1® process - Foundations is intended for the construction of all types of shallow foundations or reinforced concrete slabs for new or existing buildings, with or without infrastructure levels.
• Residential building for 1st, 2nd, 3rd, and 4th ;
• Public establishment, from 1st to 5th category ;
• Buildings subject to the Labor Code;
• Foundation for wind turbine, solar panels, etc.
The CSTB has approved an ATEX type A for Materrup floor slabs
Any industrial premises such as factories, workshops, warehouses, storage, etc., regardless of their operating loads.
• Commercial premises or similar, such as a store, shop, hall, storage, cold room;
• Individual houses, attached garages, and basements;
• Residential building for 1st, 2nd, 3rd, and 4th family, collective housing, or accommodation purposes.
• Public establishment, from 1st to 5th category, administrative or office, healthcare, hospital, clinic or dispensary, educational or university, sports, entertainment, exhibition, or place of worship;
• Garage or parking facilities for light vehicles;
• Agricole ;
• Outdoor areas (staging area, storage, etc.) with a use other than roadway.
A technical equivalence validated by the CSTB
In May 2025, the French Scientific and Technical Center for Building (CSTB) granted a new Evaluation Technique de Produits et Matériaux (ETPM – Technical Evaluation of Products and Materials) certification for our cold-activated clay cement.
This ETPM serves as the identity card of Materrup’s clay cement MCC1® and confirms its full technical equivalence with conventional CEM-type cements under the NF EN 197-1 standard, based on fundamental criteria..
It enables us to deploy the Cold-activated Clay Cement® technology with our ready-mix concrete partners, precast manufacturers, 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.
