<p>There is described a preparation of impermeabilizing membranes (in particular with an impermeabilizing matrix of a bituminous type) provided with a glass filament reinforcement, following the hereunder indicated procedures: (a) preparation of a glass filament mat achieved by the deposition from above, on a surface in horizontal movement, and with a greater speed than the traverse speed of said surface, of sized glass filaments endowed with a spirallike dropping motion; (b) deposition of impermeabilizing material in a liquid form on the mat, substantially impregnating the mat; (c) solidification of the impermeabilizing material. m</p> |
