Wall E+ - High-performance construction system optimizing the lifecycle of buildings and opening up to an infinite use of their materials for new constructions

WallE+ is a performant, simple, and circular reversible material. it's an industrialized element that can be used as the only structural and insulating material of constructions, from the foundation to the roof. Easily assembled and unassembled without alterations, it extends the lifetime of a building with its great modularities options and can infinitely be reused in other constructions. This is a new material opening a field of resilient, neutral, and circular buildings.

Key features

  • 45kg / m2 on a structural wall (10 times lighter than all alternatives)
  • Top performance insulation element ( RU=6,4 ) insuring the complete function of framework and building envelope ( floor, walls, roof) .
  • 100% Tridimensional stability in all conditions ( heat, humidity, etc ...)
  • 0% demolition = 0% waste = 100 % disassembled and reused
  • Reduce around 30% the carbon cost of the building construction even on the first use
  • Need 15 to 20 times less sand than for a concrete building


  • No need for concretes foundation = a gain of 20 days minimum on delivery & savings up to 9%
  • A unique value chain for building owners and a total detention cost lower than other comparatives alternatives by a minimum of 20%
  • -50% labor cost on the global construction cost and solve the 30 % of non-quality hidden costs usually noted in the construction sector
