NTIB process, innovative solution :

The NTIB process is an innovative solution, the result of several years of R&D, aimed at reducing the carbon footprint of buildings.
Patented in France and internationally, validated and approved by CSTB and DEKRA inspection, it is a new floor process that reduces the volume of concrete by up to 50% and the quantity of steel by about 20% in the structural works of a building, by using metal profiles with connectors, associated with a compression slab of only 8cm thick, without any use of props.
In addition to the new mixed floor process, the company has developed its own reference system HEI (Habitat Ecologique Intégré), grouping together several ecological solutions in the building sector.

The NTIB process has several advantages over conventional floors, allowing for simplicity and speed of execution.


  • No use of props resting on the ground, even for spans up to 12m
  • Non-lost and reusable formwork or without formwork using the precast variant (off-site)


  • Better resistance to seismic stress
  • Higher operating loads


  • Immediate intervention of the teams of the secondary lots
  • Moins de besoin en transport des matériaux (BPE, Acier, coffrage…)
  • Better ergonomics of the site
  • No disturbance of the current practices of the building site

Impacts of reducing concrete volumes with NTIB


  • Current spans up to 12m
  • Overhangs of up to 6m allowing for the creation of hanging gardens that are true carbon sinks


  • Lower cost (less concrete, less steel, less transportation)
  • Gain on the execution time
  • Additional gain on the execution time with the use of precast slabs
  • Productivity gain (labor, props assembly…)
  • Carbon tax avoided


  • Significant reduction of global GHG emissions
  • Reduction of the overexploitation of non-renewable natural resources
  • Reduced the carbon footprint of the building, thus amply meeting the requirements of the RE2020

NTIB, A solution with high GHG reduction potential

On the whole life cycle, the NTIB process allows an unprecedented and immediate reduction of the carbon footprint of the building, approved by comparative LCAs carried out by two firms specialized in LCAs in France, from :

  • The reduction to half of the consumption of non-renewable natural resources (Water, Sands, Aggregates, ...),
  • The reduction of 33% of the carbon footprint of the structural works, thanks to the reduction of concrete volumes, and even more for high-rise buildings,
  • Significant reduction of steel quantities of about 20%, or even more for high-rise buildings,
  • The reduction to half of the use of limestone (the basis of cement production).

Positive impact of NTIB on key stages of the building life cycle
