Definitions

• the present invention relates to a modular shuttering element for a building wall.
• planelles of these modular elements have a sufficiently neat appearance that it is not necessary to coat them, which also leads to cost reductions. That said, it has been observed that the walls constructed with modular shuttering elements from all of the prior techniques systematically exhibited air and water tightness defects due to the bridging effect inevitably produced by the spacers. According to this effect, air and water manage to pass through the wall along the undersides and sides of the spacers.
• the poured concrete shrinks all of the internal faces of the modular elements, and in particular on the undersides and on the sides of the spacers.

• the complementary sockets of the projections 8a, 8a 'and the grooves 8b, 8b' longitudinal on the one hand, and the lateral parts on the other hand make it possible to form mechanical barriers which oppose dynamic water infiltration , that is to say in the infiltration of moving water (in the case of rain knocked down by the wind against the wall, for example).
• the clearances between the projections 8a, 8a 'and the longitudinal grooves 8b, 8b' make it possible to produce separation zones between modular shuttering elements in which the water can hardly progress by capillarity. In this way, physical barriers to water infiltration are formed.
