M10+ Mortar & Materrup Blocks: The Solution to Reduce Carbon in Your Renovations

Renovating instead of demolishing, transforming existing structures in the heart of La Défense #Paris is never trivial.

With the #NIRVANA project, the teams from Bouygues Immobilier and Bouygues Bâtiment Ile-de-France – Private Renovation take on a major challenge: restructuring and expanding the former BEING office building while actively reducing the project’s carbon footprint..

Across nearly 20,500 m², the site combines heavy renovation, urban infill expansion, and high environmental ambitions (BBCA, 2028 threshold, reuse). A demanding environment where every technical decision carries weight.

When the goal is clear — to reduce real carbon impact — the solution is not to overcomplicate things, but to do things differently..

👉he project teams made a strong choice: replace traditional cement with our MCC1® cold-activated clay cement, integrated into a turnkey solution: our hollow blocks and Materrup mortar :

🧪 Materrup Mortar, formulated with MCC1® cement:

➡️ Carbon footprint 4 times lower than conventional mortar

➡️ Packaged in 25 kg bags: practical, simple, and immediately usable

➡️ Easy to source, store, and apply

➡️ No change to on-site working methods

➡️ A competitive product, designed for the realities of renovation projects

🧱 Materrup Low-Carbon Hollow Blocks :

➡️ 6.44 kg CO₂ eq / m² for a rectified B40 block

➡️ Even lower impact when paired with our mortar

➡️ Circular blocks, made from reused waste

➡️ CE-marked, durable, fully substitutable for traditional solutions

➡️ EPDs verified by independent experts

At MATERRUP Low Carbon & Circular Cements, we believe in simplicity.

Because to accelerate the sector’s transition, every player in the value chain must be able to act without constraints, without complexity, without changing their practices..

The NIRVANA project proves it:

👉 Renovate intelligently,

👉 Change the cement,

👉Make low-carbon solutions operational, here and now..

You too can do better — follow their lead!
