  • Manufacture and method of installing, notably construction panels formed in a closed mold
    Patent number: 6871461
    Abstract: The present invention concern the fabrication of panels (11) (12) in which the elements (2) are assembled by gussets (3) (13) during the preparation in the mold. A porous facing (5) constituting an external side that allows degassing (6) that is a result of the expansion of reactive products. The porous surface facing (5) is only impregnated (7) leaving the external surface of the panel rough for the future application of a coating. The present invention allows for a perfect water tight seal (11) (12) between the panel, the ground and the frame with junction profile (16) and a tube for the injection of products (18) with no cavities to be filled-up after set-up.
