Our key strenghts
of French wood by volume
The wood aggregates used in the cement matrix are sourced from French “wood for pulp” — a co-product of sustainable forest management. This local sourcing qualifies them for the “Bois de France” certification.
Carbon footprint
The carbon storage generated by the wood aggregates is so significant — and lasts throughout the entire lifespan of the material — that some of our construction solutions achieve a negative carbon balance (as demonstrated by five verified EPDs available on the INIES database). Whether the balance is highly negative or slightly positive, the key takeaway is that it enables compliance with the 2031 thresholds of the RE2020 regulation.
Off site construction
All our solutions — TimberROC® and ParkROC® — are based on off-site construction. Prefabricated elements significantly reduce installation time on site, minimise the risk of workplace accidents, and ensure cleaner, more efficient worksites with much lower water consumption.
New construction / Walls and floor slabs
Load-bearing walls up to four storeys, infill façades up to ten storeys, and off-site manufactured floor slabs enable the construction of all types of low-carbon, bio-based buildings while ensuring comfort and safety for occupants.
Thermal mass and time lag
17-hour thermal time lag and 98% damping for a 30 cm load-bearing wall.
Guaranteed summer comfort
Maintains indoor temperatures below 26 °C even after several consecutive heatwave days. Client feedback and performance reports available.
Acoustic absorption
An αw coefficient of 0.70 drastically reduces sound reverberation.
High fire resistance
REI 60 to 120 min – Class A2-s1-d0 for walls, and REI 240 min for floor slabs.
Outdoor spaces / Car parks and pedestrian walkways
ParkROC® is a wood-based concrete permeable slab that halves the carbon footprint of a conventional surface, absorbs up to 120 L/min/m², and helps reduce urban heat islands. Ideal for pedestrian pathways, light vehicle car parks, and sustainable landscape developments.
Frost-resistant / Freeze–thaw cycles
No chipping or cracking after 30 cycles + de-icing salts
Stormwater management
> Effective stormwater management, with drainage rates exceeding 120 L/min/m² and a retention capacity of 40 L/m².
A shared expertise
A network of prefabrication partners close to every project
We transform wood into aggregates.
We transform wood into aggregates.
Thanks to them, TimberROC® technology is deployed across France, as close as possible to each construction site — reducing transport distances and ensuring high-quality implementation. They support project teams from the design stage, through an integrated design office dedicated to wood-based concrete, right up to the delivery of prefabricated elements on site. Training for installation teams can also be provided.
They have already delivered projects built with wood-based concrete!
The first multi-family building in France made of wood-based concrete was completed in 2022 in Bonson (Loire, 42).
